Getting Started

What is the Google Maps Platform?

The Google Maps Platform is a set of APIs and SDKs that allows developers to embed Google Maps into mobile apps and web pages, or to retrieve data from Google Maps. There are several offerings. Depending on your needs, you may find yourself using one or a combination of these APIs and SDKs:

Maps:

Routes:

Places:

Environment:

How do I get started with Google Maps Platform?

See Get Started with Google Maps Platform.

Which API do I need?

For help in finding the right API based on your functional requirements, take a look at the API picker.

How do I start using the APIs on my site?

See the Overview, Developer, and Get Started guides for the specific API or SDK you are interested in. For example, check out the guides for Maps SDK for Android or Maps JavaScript API.

Which countries does the Google Maps Platform cover?

The Google Maps team is constantly pushing new map data out and increasing our international coverage. Consult the Google Maps coverage data for the latest coverage information. You can filter the data with the filter box at the top of the page. Please note that coverage data can change if licensing agreements with the data providers change.

Can I put Google Maps on my site without using Google Maps Platform products?

Yes. Google Maps now offers the ability to embed the map that you're viewing into your website or blog, without any programming or use of the Google Maps Platform. More information is available here.

How do I deliver Maps applications on mobile devices?

To incorporate maps in an Android application, use the Maps SDK for Android.

To incorporate maps in a native iOS application, use the Maps SDK for iOS.

The Maps JavaScript API has been developed to cater to mobile devices, and is suitable for browser applications targeted at both the desktop and devices that include a web browser with a full JavaScript implementation, such as the Apple iPhone.

For applications targeted at devices not suitable for using the Maps JavaScript API, the Maps Static API delivers map images in GIF, JPG, and PNG formats, including markers and polylines. Note that use of the Maps Static API outside of browser based applications requires that the map image be linked to Google Maps.

Which web browsers do the Maps JavaScript API and Maps Embed API support?

The Maps JavaScript API and Maps Embed API support the following web browsers:

Desktop

The current version of Microsoft Edge (Windows), excluding IE mode.
The two latest major stable versions of Firefox (Windows, macOS, Linux).
The two latest major stable versions of Chrome (Windows, macOS, Linux).
The two latest major stable versions of Safari (macOS).

Android

The current version of Chrome on Android 4.1+.
Chrome WebView on Android 4.4+.

iOS

Mobile Safari on the current and previous major versions of iOS.
UIWebView and WKWebView on the current and previous major versions of iOS.
The current version of Chrome for iOS.

Can I print maps from the Maps JavaScript API?

Printing from the Maps JavaScript API is not supported. This is because printing support is inconsistent across commonly used browsers.

How can I be notified when there are changes to Google Maps Platform products?

You should subscribe to the Google Maps Platform Blog for news updates across the various Google Geo developer offerings.

How do I contact technical support?

See Google Maps Platform Support and Resources for information about available support options.

When is technical support available?

The support team is available 24x5 (weekdays from Monday 9 a.m. Tokyo time to Friday 5 p.m. Pacific time) excluding regional holidays for "service unusable" issues.

How can I recover access to my Google Account?

If you lost access to your Google Account (e.g. [email protected] or [email protected]), you can try restoring the account access by retrieving or resetting your password. Visit the How to recover your Google Account or Gmail article in Google Account Help.

Note: To restore access to a G Suite account, ask your Organization admin to undelete the account.

How can I recover access to a specific project?

If you lost access to the project where you manage your Google Maps Platform implementation, you can try to recover it.

If you have access to your project-associated Google Account:

If you know the Project Owner and have access to your Google Account: Ask the Project Owner to add you as a Project Owner or Project Editor.
- If your project is part of an Organization: Contact your Organization admins and ask them to add you as a Project Owner.
If you do not know any of the current Project Owners: If you don’t know who the Project Owner is, or the Project Owner is unavailable, contact the support team to explore additional options to recover the project.

If you do not have access to your project-associated Google Account:

If you lost access to your Google Account: try to recover your username or password for your account.
If you cannot recover access to your Google Account: Create a new Google Account, then contact an existing project owner and ask them to add your new Google Account to the project.

Can I use the Maps and Places SDK for iOS on Arm-based Macs?

Developing on the new Arm-based Macs is possible, however, it requires building and running on a physical iOS device. This is a temporary limitation while we look into adding more support for developing on simulators.

Understanding the terms of service

What are the terms of service for Google Maps Platform products?

The Google Maps Platform Terms of Service are available at:

https://cloud.google.com/maps-platform/terms

Does my site meet the Google Maps Platform Terms of Service?

You can use the Google Maps Platform within your applications as long as your site meets the Google Maps Platform Terms of Service.

However, there are some uses of the Google Maps Platform that we just don't want to see: maps that identify the places to buy illegal drugs in a city, for instance, or any other illegal activity. We also respect people's privacy, so the Google Maps Platform shouldn't be used to identify private information about individuals.

You should use your own counsel to determine whether your application complies with the Google Maps Platform Terms of Service before you develop and launch it. Google engineers can only offer technical assistance and are not qualified to offer legal advice. Google reserves the right to suspend or terminate your use of the service at any time, so please read the Maps APIs Terms carefully.

Can I directly access map tiles and satellite imagery?

You may not access map tiles or satellite imagery through any mechanism besides the Google Maps Platform (such as the creation of your own mapping API or the use of a bulk tile download script). Your application's access to the tiles will be blocked if it accesses them outside of the Google Maps Platform. See the Google Maps Platform Terms of Service for more details.

Can I use Google Maps Platform products for tracking applications?

There is no restriction on displaying real-time data (tracking) with Google Maps Platform products provided that the application complies with the Google Maps Platform Terms of Service.

Can I use Google Maps in my non-Web application?

Yes, Google Maps Platform products can now be used in non-Web applications, provided that they adhere to the other restrictions of the Google Maps Platform Terms of Service.

The Maps JavaScript API is only supported when run in one of the supported browsers.

Can I use Google Maps Platform products on a site that is password protected?

Yes, Google Maps, Routes, Places, and Environment services can be used with private-access applications. See the Google Maps Platform Terms of Service for more details.

Can I create an application that includes Google Maps Platform data in a document?

If your application generates a document, either in electronic or printed form, no data from Google Maps Platform, including images, may be included in the document. Please see the Google Maps Platform Terms of Service "No Scraping" section for more details.

How can I opt out of including my content in Google search results?

We are no longer collecting this data. The use of the indexing parameter has been deprecated and has no effect. You no longer need to opt out explicitly, but we encourage you to remove this parameter at your earliest convenience.

To remove your page or site from search results, follow the instructions provided in our webmaster help center.

Can I generate a map image using the Maps Static API which I store and serve from my website?

You may not store and serve copies of images generated using the Maps Static API from your website. All web pages that require static images must link the src attribute of an HTML img tag or the CSS background-image attribute of an HTML div tag directly to the Maps Static API so that all map images are displayed within the HTML content of the web page and served directly to end users by Google.

Usage limits and billing

How do I set up billing for my project?

See Get Started with Google Maps Platform.

How do Google Cloud Platform Free Tier customers upgrade to a paid account?

The Google Cloud Platform Free Tier program provides customers a no-charge trial with a $300 credit to use with any Google Cloud service, including the Google Maps Platform (GMP) APIs. When the no-charge trial period ends, you must upgrade to a paid account to continue using these services. To upgrade to a paid account, visit the Cloud Console.

Does the Google Maps Platform have usage limits?

There are no maximum daily limits on the number of requests you can make to Google Maps Platform products, and the only usage limits are related to the maximum number of queries per minute (QPM).

For Distance Matrix, the limit is set in events per minute (EPM) calculated as the sum of client-side and server-side queries.

For Routes:Compute Route Matrix, the limit is in elements per minute (EPM), where the number of elements in a request is equal to: (number of origins times number of destinations).

For the Navigation SDKs, each destination in a request is counted as a separate query.

The following table shows the usage limit for each API.

API	Usage limit
Address Validation	6,000 QPM
Aerial View: Lookup Video	180 QPM and 100,000 QPD
Aerial View: Render Video	100 QPM and 100 QPD
Air Quality	6,000 QPM
Directions	3,000 QPM
Distance Matrix	60,000 EPM
Dynamic Maps	30,000 QPM
Elevation	6,000 QPM
Geocoding	3,000 QPM
Geolocation	6,000 QPM
Map Tiles API: 2D Tiles and Street View Tiles	6,000 QPM and 15,000 QPD
Map Tiles API: Photorealistic 3D Tiles	10000 QPD
Map Tiles API: Photorealistic 3D Tiles: Renderer	12,000 QPM
Navigation: Set destination requests	30,000 QPM
Places	6,000 QPM
Pollen	6,000 QPM
Roads	30,000 QPM
Routes: Compute Routes	3,000 QPM
Routes: Compute Route Matrix	3,000 EPM
Solar	600 QPM
Static Maps	30,000 QPM
Street View Image API	30,000 QPM
Time Zone	30,000 QPM

In order to govern expenditures, you can monitor your API usage, and set daily limits to all requests to any billable API.

Google Maps Platform products must be deployed in compliance with the standard Google Maps Platform Terms of Service.

How is usage cost calculated?

For an overview of pricing for the Google Maps Platform products, please see the Pricing Sheet.

To learn more about how Google Maps Platform APIs are billed, please see Understanding billing for Maps, Routes, Places, and Environment.

How are map loads counted on the Google Maps Platform?

A single map load is charged when any of the following occur:

A web page or application displays a map using the Maps JavaScript API.
An application requests a single map image from the Maps Static API.

Street View panoramas are charged separately from map loads:

A static Street View panorama is charged for each request to the Street View Static API to embed a static (non-interactive) Street View panorama.
A dynamic Street View panorama is charged for each instantiation of a panorama object in a Maps JavaScript API, Maps SDK for Android, or Maps SDK for iOS application.

After a web page or application loads a map, or a static map image, or a Street View panorama, any user interactions with it, such as panning, zooming, or switching map layers, do not generate additional map loads or affect usage limits.

Adding a marker will not generate additional map loads, but may generate charges around how the pin location was determined (such as loading or reloading the `google.maps.Map()` class.)

How do I monitor my usage?

You can monitor the usage of individual APIs in the Google Cloud Console.

Select the project that contains the API you want to review.
From the list of APIs on the Dashboard, click the name of the API.
Near the top of the page, click Metrics or Quotas.

To see a traffic report and billing information for an entire project, follow these steps:

If you haven't already done so, set up billing.
Go to the Cloud Console billing page.
Select a project.
In the left sidebar, click Reports. Use the filters on the right sidebar to view reports on your billing account.

To learn more, see Google Maps Platform Reporting as well as Monitoring your API Usage and Capping API Usage.

What happens if I exceed the request rate (QPM) limits?

If you exceed the QPM limits of a given Google Maps Platform product, the API will return an error message. If you repeatedly exceed the limits, your access to the API may be temporarily blocked.

If you exceed the request QPM limits or otherwise abuse the service, requests will return a specific error message. If you continue to exceed limits, your access to the Google Maps Platform may be blocked.

Note: Four of the web service APIs have an equivalent client-side service available in the Maps JavaScript API: Directions, Distance Matrix, Elevation, and Geocoding.

Usage limits exceeded

If you exceed the usage limits you get an OVER_QUERY_LIMIT status code as a response.

This message means that the web service has stopped providing normal responses and has switched to returning only status code OVER_QUERY_LIMIT until more usage is allowed again. This scenario can happen within a few seconds, if the error was received because your application sent too many requests per minute.

If you regularly exceed your QPM usage limits, consider lowering usage by optimizing applications to use Google Maps Platform products more efficiently, or request to increase your quota. See the Optimization Guide for more information.

My site gets a lot of traffic. Can I use Google Maps Platform products?

Yes. However we recommend that you familiarize yourself with the usage limits for any of the Google Maps Platform that your application relies on.

If my web site or application becomes suddenly popular, will my maps stop working?

Once you have a billing account, if you exceed the no-charge, $200-monthly usage limit and you do not have a valid payment method on your billing account (credit card, bank transfer, ...), the API ceases to function until you add a valid payment method.

How will usage be calculated and billed?

Usage is calculated at the end of each day, and priced as shown in the Pricing Sheet. At the end of every month, the total usage is charged to the payment method associated with your billing account. For more information, see Google Maps Platform Billing.

How much does it cost to use the Google Maps Platform?

See the Pricing Sheet for an overview of cost per API. If your application generates requests or map load volumes up to $200 per month usage, your usage is not charged. Usage that exceeds the $200 monthly credit will be charged to your billing account. For more details, see our guide to understanding Google Maps Platform billing.

Is pricing available in other currencies?

Additional currencies may be available within the console. When you select a different currency, rates will convert from the USD equivalent listed on our Pricing Sheet.

I've set up billing. How do I view my bill?

Google charges you at the beginning of each month for the previous month's activity, using your specified payment method. For details about your bill, see our guide to understanding Google Maps Platform billing.

Additional resources:

Learn how to view your cost and payment history.
Learn how to get an invoice or payment receipt.
Learn how to set and manage billing alerts.

How do I avoid a large bill if my usage unexpectedly increases?

The Google Maps Platform provides ways to set daily request limits and set maximum daily billable limits. You can cap the maximum daily limit on usage to protect against unexpected increases. You can also set budget alerts to receive email notifications when the charges on the billing account reach a threshold you set.

Capping the maximum daily billable limit:

To avoid a large bill, you can set a daily cap on usage to protect against unexpected increases in use. You can change this limit in the Cloud Console by taking the following steps:

Go to the APIs & Services Dashboard.
Select a project if prompted.
Select an API from the list, then click the Quotas tab.
Click the edit icon next to the "requests per day" quota.

Alternatively, you can edit multiple quotas for multiple APIs using the IAM & admin Quotas dashboard.

Setting and managing budget alerts:

Set up budget alerts to send email notifications to billing administrators when the charges on the billing account reach a threshold you set. Billing administrators will be sent email notifications when the estimated charges on the billing account exceed 50%, 90%, and 100% of the threshold.

I got a message saying that my project is linked to the "Google Maps Platform Transition Account", but I don't have access to that account. What do I do?

The "Google Maps Platform Transition Account" was created to help certain customers transition to our new pay-as-you-go pricing plan. This transition account enabled Google to provide these customers with a one-time credit, so that they could continue using Google Maps Platform up to the limit of the $200 no-charge tier. Once this limit is exceeded, the billing account will shut down and you will lose access to the service. To avoid service interruptions, we urge you to set your own billing account, and continue to enjoy the $200 monthly no-charge tier. To change the billing account for your project:

Create a new billing account (if you already have a billing account, you can skip this step).
Associate the billing account with your project.

Why is my quota limit set to 1 request per day? How can I raise this limit?

If you have not created and attached a billing account to your project, your Maps Platform APIs will be limited to 1 request per day. You can get higher quota by creating and attaching a billing account. To do this, see Get Started with Google Maps Platform.

Once you have created and attached a billing account, your daily quota limit will be removed. You can decide to set a limit to prevent unexpected spend, in the Cloud Console.

I received a billing violation notice. How do I resolve this?

You have received this notice because Google has determined that your account has been using multiple billing accounts. This is a violation of Google's terms, as defined in section 3.2.4 of the Google Maps Platform Terms of Service. Under these terms, it is forbidden to create multiple billing accounts. To learn more, see the Billing Account Violation FAQ.

Using the Google Maps Platform

Which keys or credentials should I use for different Maps products?

Each time you use Google Maps Platform products, you must include an API key to validate your request. The Google Maps Platform is available for Android, iOS or Web apps, and via HTTP web services.

API Key:

An API key is a unique identifier that you generate using the Cloud Console.
Example of loading an API with a key: &key=AIzaSyBjsINSH5x39Ks6c0_CoS1yr1Mb3cB3cVo

Digital Signature:

A digital signature is generated using a URL signing secret provided to you by Google. Digital signatures are used with the Maps Static API and Street View Static API.

Restrictions:

API key restrictions are optional, but we strongly recommend you restrict all API keys for greater security. See API security best practices for more details.
You can add an application restriction to the API key. Once restricted, a key will only work on platforms that support that type of restriction. Four types of application restrictions are available. APIs enforcing the same restriction type can use the same restricted key.
- IP addresses (individual servers) - for use with the web service APIs.
- HTTP referrers (web sites) - for use with the web APIs.
- Android app restriction (by package name and fingerprint) - for use with the Maps SDK for Android.
- iOS app restriction (by iOS bundle identifier) - for use with the Maps SDK for iOS.
You can also add an API restriction to the API key. For more information, see Get, add, and restrict an API key.

The table below indicates the key/credential and application restriction for each Google Maps Platform API/SDK.

API/SDK	Credential & Application Restriction
Maps SDK for Android	API key with Android restriction¹
Places SDK for Android	API key with Android restriction¹
Navigation SDK for Android	API key with Android restriction¹
Maps SDK for iOS	API key with iOS restriction¹
Places SDK for iOS	API key with iOS restriction¹
Navigation SDK for iOS	API key with iOS restriction¹
Maps JavaScript API	API key with HTTP referer restriction¹
Map Tiles API	API key with IP address restriction¹
Maps Datasets API	OAuth token
Aerial View API	API key with IP address restriction¹
Maps Static API	API key with HTTP referer restriction¹ + Digital Signature²
Street View Static API	API key with HTTP referer restriction¹ + Digital Signature²
Maps Embed API	API key with HTTP referer restriction¹
Address Validation API	API key with IP address restriction¹
Directions API	API key with IP address restriction¹
Distance Matrix API	API key with IP address restriction¹
Elevation API	API key with IP address restriction¹
Geocoding API	API key with IP address restriction¹
Geolocation API	API key with IP address restriction¹

Routes API	API key with IP address restriction¹
Time Zone API	API key with IP address restriction¹
Air Quality API	API key with IP address restriction¹
Pollen API	API key with IP address restriction¹
Solar API	API key with IP address restriction¹

¹ API key restrictions are optional, but we strongly recommend you restrict all API keys for greater security.

² Depending on usage, a digital signature may be required for the Maps Static API and Street View Static API. Regardless of usage, we strongly recommend that you use both an API key and a digital signature to authenticate your requests.

How do I switch my key restriction type from an HTTP referer to an IP address restriction?

Important: If you are using any of the web service APIs with an API key that has referer restrictions, your requests will fail with the error message: "API keys cannot have referer restrictions when used with this API." You should switch to using an API key with IP address restrictions.

Before you switch the API key restriction type from HTTP referer to IP address, ensure that all the APIs that use the API key support the IP restriction type. APIs of the same restriction type can use the same restricted key. If you need to enforce more than one restriction, add a separate key with the required restriction. See how to add a new API key.

Learn more about API key restrictions associated with Google Maps Platform products.

To switch an API key with HTTP referer restriction to IP address restriction, do the following:

Go to the Credentials page of the Cloud Console.
Select the project that contains the API key you want to edit.
On the Credentials page, from the list of API keys, select the name of the API key to edit the details of the key.
In the Key restriction section of the page, select “IP addresses (web servers, cron jobs, etc.)” and insert the appropriate server IP addresses, then click Save.

How do I get a new API key?

See Get Started with Google Maps Platform.

How can I find the changes introduced in each version of the Google Maps APIs?

Version change information for many of the Maps APIs are available at the following links:

You can also check which version of the Google Maps Platform a particular bug was introduced and fixed in using the Google Maps Platform Issue Tracker at:

https://issuetracker.google.com/bookmark-groups/76561

How can I load the API into a page asynchronously after the page has loaded?

Just specify the callback parameter when loading the API. More information and sample code can be found in the Getting Started chapter of the Maps JavaScript API documentation.

How can I get Google Maps Platform products to display in a language other than English?

By default the API will attempt to load the most appropriate language based on the users location or browser settings. Some APIs allow you to explicitly set a language when you make a request. More information on how to set the language is available in the documentation for each API:

Can the Google Maps Platform be accessed over SSL (HTTPS)?

The Maps JavaScript API, Maps Static API, and Web Service APIs can be accessed over secure (HTTPS) connections. Please see the documentation for the API concerned for information on how to access the API over SSL.

Note that the Maps Static API does not support custom icon URLs that use HTTPS; the default icon will be displayed.

How do I report a bug or request a new feature in the Google Maps Platform?

If you experience behavior that you believe may be a bug, please begin by raising it in the relevant forum. This will allow other developers to validate the bug, and rule out any potential issues with your code.

If you wish to request a feature, please also first raise it in the relevant forum to confirm that a solution that meets your requirements is not already available.

Once you have confirmed that you have identified a new bug, or that your requirements cannot be met by the existing functionality of the Google Maps Platform products, please report your bug or feature request using the Google Maps Platform Issue Tracker.

Before adding a bug or feature request to the Issue Tracker please be sure to check that the bug or feature concerned has not already been added. If it has, you can star the issue to register your interest and be notified of updates.

How do Google Maps Platform APIs use site cookies?

Maps SDK for Android and Maps SDK for iOS use cookies subject to Google's Privacy Policy, such as calculating daily and 7-day active users and service abuse prevention. These cookies are not associated with any signed-in Google Account and are not logged with the rest of the information collected from the API calls.

I can't find the answer to my question. Who should I contact?

Google's Developer Relations team maintains a presence on Stack Overflow — a collaboratively-edited question and answer site for programmers. It's a great place to ask technical questions about developing and maintaining Google Maps applications. More information about asking questions on Stack Overflow is available on the Support page.

For best results when requesting help, please keep the following in mind:

Search the current discussions. Chances are someone else has experienced a similar issue and found a fix.
Submit a link to your site if possible. Only post code snippets if the code is not easily viewable online.
Provide all relevant information including browser versions, errors, and all other facts that may be useful in troubleshooting this problem.

Errors and troubleshooting

What does this error mean?

If you encounter an error while loading or running the Google Maps APIs, please see the following links to find explanations for the error codes:

My maps appear darker than usual. What's happening?

Under certain circumstances, a darkened map, or 'negative' Street View image, watermarked with the text "for development purposes only", may be displayed. This behavior typically indicates issues with either an API key or billing. To use Google Maps Platform products, you must have a billing account and all requests must include a valid API key. The following flow will help troubleshoot this:

Are you using an API key?

I'm not sure. How can I check if I am using an API key?

An API key is passed as the key parameter in the URL that is used to load the Maps JavaScript API. Here are a few options to check if you are using an API key:

Use the Google Maps Platform API Checker Chrome extension. This allows you to determine if your website is properly implementing Google’s licensed Maps APIs.
If you are using a library or plugin to load the Maps JavaScript API, check the settings for that library and look for an API key option.
Check errors in your browser. If you see the following messages, you are not using your API key correctly:

Google Maps JavaScript API warning: NoApiKeys
Google Maps JavaScript API error: MissingKeyMapError

For web developers:

If you have access to the source code of your application, look for the <script> tag which is used to load the Maps JavaScript API. When loading the Maps JavaScript API, substitute YOUR_API_KEY in the code below with your API key.
```
  <script async defer
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
  </script>
```
Check the network traffic generated by your website in the browser. In Chrome, this can be viewed using the DevTools Network tab. Here you will see the network requests made by your website. Requests made using the Maps JavaScript API will be under the path maps/api/js. Here you can confirm if the requests are using the key parameter. It may be helpful to filter your network traffic by maps/api/js when viewing the Network tab.

No, I am not using an API key.

To get an API key, click the button below. If you do not see a guided setup, follow the full instructions at Get Started with Google Maps Platform.
Get Started

Yes, I am using an API key.

Great! Let’s move on and check if a billing account is attached to your project.

Is a billing account attached to your project?

I'm not sure. How can I check if billing account is attached to my project?

Go to the Billing page in the Google Cloud Console and select the project under which your API key was created. To confirm the key is associated with the project:

Go to the Credentials section, which can be accessed from the left side bar under Google Maps Platform > Credentials.
Check that the API key you currently use on your website is listed. If that's not the case, switch to a different project, and check the credentials there.
If you cannot locate the project for your API key, you may have lost access to this project. Ask others in your organization for help. If the original project cannot be located, you should:
1. Create a new project. This can be done by selecting New Project from the projects list, or by selecting Create Project via the Resource Manager page.
2. Create a new API key. This can be done on the Credentials page. Once there click Create credentials and then select API key.

Once you have located your project in the Cloud Console, check if a billing account is attached by navigating to the Billing section in the left side menu.

No, a billing account is not attached to my project.

Go to the Enable Billing page in the Cloud Console and add a billing account to your project. For additional information, see Get Started with Google Maps Platform.

Yes, a billing account is attached to my project.

Great! Let’s make sure the provided billing method is valid.

Is the provided billing method no longer valid (for example an expired credit card)?

You can add, remove, or update a payment method in the Cloud Console.

Is there an exceeded self-imposed daily limit on the API?

If you have set a daily limit on any of your APIs, which is common to prevent unexpected increases, you can resolve this by increasing your daily limit.

You can check your daily limits by going to the APIs & Services Dashboard in the Cloud Console. Once there:

Select a project if prompted.
Select an API from the list, then click the Quotas tab.

Does your API key have an IP addresses restriction?

API keys with an IP addresses restriction can only be used with web services that are intended for use from the server side (such as the Geocoding API and other Web Service APIs). Most of these web services have equivalent services within the Maps JavaScript API (for example, see the Geocoding Service). To use the Maps JavaScript API client side services, you will need to create a separate API key which can be secured with an HTTP referrers restriction (see Get, add, and restrict an API key).

How do I resolve the error codes: OVER_DAILY_LIMIT or OVER_QUERY_LIMIT?

These error codes can be returned for any of the following reasons:

An API key is missing from the request.
The provided API key is invalid.
The project does not have a billing account attached.
A self-imposed usage cap has been exceeded.
The provided method of payment is no longer valid (for example, a credit card has expired).
You have exceeded the quota limits for a given API.

To use Google Maps Platform products, you must have a billing account, and all requests must include a valid API key. To fix this, take the following steps:

Set up a billing account.
Get a new API key.
Adjust your usage cap to increase your daily limit (if applicable).

How do I resolve the error codes: kGMSPlacesRateLimitExceeded or 9005 PLACES_API_RATE_LIMIT_EXCEEDED?

If you are seeing kGMSPlacesRateLimitExceeded or 9005 PLACES_API_RATE_LIMIT_EXCEEDED, you may be using a deprecated version of the Places SDK for Android or Places SDK for iOS. Learn more and find the new SDKs at https://goo.gle/places-sdk-deprecation.

How do I resolve the error: "This IP, site or mobile application is not authorized to use this API key."?

There are various scenarios which may cause this error:

You've enabled IP address (server) restrictions on your API key, and an unauthorized IP address is attempting a request.
You've enabled HTTP referrer (website) restrictions on your API key, and an unauthorized referrer is attempting a request.
You've restricted usage to your Android apps by setting a package name and fingerprint, and an unauthorized Android app is attempting a request.
You've restricted requests from iOS apps by specifying bundle identifiers and an unrecognized iOS app is attemting to send a request.
It used to be possible to get this error if you used any of the web service APIs, with an API key with HTTP referer restrictions. Requests to those APIs should be identified with an API key with IP address restrictions. Switch your key restriction type from an HTTP referer restriction to an IP address restriction. For more information about restricting API keys, see API Key Best Practices.

View and Edit your API Key Credentials

To view your API keys and manage any restrictions, do the following:

Go to the Credentials page of the Cloud Console.
Select the project that contains the API key you want to review.
To view credential details, including any restrictions set for the key, from the list of API keys, click the name of the key.
The full credentials of the selected API key are displayed, including any restrictions set up for the key. From here, the restrictions can be changed, deleted, or updated as needed.

How do I resolve the error: "API keys with referer restrictions cannot be used with this API."?

You are using any of the web service APIs with an API key restricted to an HTTP referer. For security reasons, web service APIs need to use API keys restricted to IP addresses. Switch your key restriction type from an HTTP referer restriction to an IP address restriction, or create a new API key if your key is already used with the Maps JavaScript API.

Google Maps Platform Services

I need to convert addresses to latitude/longitude pairs. Can I do that with the Google Maps Platform?

Yes, this process is called "geocoding." The Maps JavaScript API includes a class for performing a geocoding service. The class is: google.maps.Geocoder.

Alternatively, Google also provides the Geocoding API, which offers a REST interface that can respond in JSON and XML formats.

Which countries is geocoding available in?

To see countries currently supported by the Google Maps Platform geocoders, please consult the Google Maps coverage data.

The accuracy of geocoded locations may vary per country, so you should consider using the returned location_type field to determine if a good enough match has been found for the purposes of your application. Please note that the availability of geocoding data depends on our contracts with data providers, so it is subject to change.

Why do the Google Maps Platform Geocoders provide different locations than Google Maps?

The API geocoder and Google Maps geocoder sometimes use different data sets (depending on the country). The API geocoder occasionally gets updated with new data, so you can expect to see results changing or improving over time.

How should I format my geocoder queries to maximise the number of successful requests?

The geocoder is designed to map street addresses to geographical coordinates. We therefore recommend that you format geocoder requests in accordance with the following guidelines to maximize the likelihood of a successful query:

Specify addresses in accordance with the format used by the national postal service of the country concerned.
Do not specify additional address elements such as business names, unit numbers, floor numbers, or suite numbers that are not included in the address as defined by the postal service of the country concerned. Doing so may result in responses with ZERO_RESULTS.
Format plus codes as shown here (plus signs are url-escaped to %2B and spaces are url-escaped to %20):
- global code is a 4 character area code and 6 character or longer local code (849VCWC8+R9 is 849VCWC8%2BR9).
- compound code is a 6 character or longer local code with an explicit location (CWC8+R9 Mountain View, CA, USA is CWC8%2BR9%20Mountain%20View%20CA%20USA).
Use the street number of a premise in preference to the building name where possible.
Use street number addressing in preference to specifying cross streets where possible.
Do not provide 'hints' such as nearby landmarks.

How should I format a U.S. address on a numbered highway for geocoding?

The Google Maps Platform geocoder requires that U.S. numbered highways be specified in addresses as follows:

County Roads: "Co Road NNN" where NNN is the road number. eg. "Co Road 82"
State Highways: "State NNN" where State is the full name of the state and NNN is the highway number. eg. "California 82"
U.S. Highways: "U.S. NNN" where NNN is the highway number. eg. "U.S. 101"
U.S. Interstates: "Interstate NNN" where NNN is the interstate number. eg. "Interstate 280"

When should I use an API geocoder class and when should I use the HTTP Geocoding Service?

See the document: Geocoding Strategies, which details the pros and cons of different geocoding strategies.

How do I provide driving directions with the Google Maps Platform?

The Compute Routes service of the Routes API and the Directions API allow you to provide driving directions for single and multi-leg journeys. Routing options help you shape directions with a travel mode (driving), a single or a set of routes, and restrictions (no toll roads). These services are available in the following forms:

HTTP request/response interface (used in mobile and other applications) is compatible with Maps SDK for Android and with other Google Maps web services.
JavaScript API, for client-side applications, allows you to provide driving directions via the google.maps.DirectionsService class. The DirectionsRenderer class can automatically create the overlays and directions panel for you. Additional examples are provided in the documentation.
Java, Python, go, and Node.js client interfaces, for server-side applications, provide the same functionality. For more information on client libraries, see Directions API client libraries.

In which countries are driving directions available?

To see countries currently supported by driving directions in the Google Maps Platform products, consult the Google Maps coverage data. Please note that the availability of driving directions data depends on our contracts with data providers, and is subject to change.

In which countries are transit directions available?

The Directions API and Distance Matrix API support all Google Transit partners, except those in Japan.

Which KML and GeoRSS features are supported in the Maps JavaScript API?

The KmlLayer class in the Maps JavaScript API enables developers to overlay KML/KMZ and GeoRSS files on top of the map. Documentation and examples can be found here.

What are the limits on the size and complexity of KML that can be displayed using the KmlLayer class of the Maps JavaScript API?

The size and complexity limits on the display of KML using the KmlLayer class are documented here.

How do I render KML files that are hosted on intranet sites on a map?

The KmlLayer class that generates KML overlays in the Maps JavaScript API uses a Google hosted service to retrieve and parse KML files for rendering. Consequently it is not possible to display KML files that are not hosted at a URL that is available publicly accessible, or that require authentication to access.

If you need to develop applications that use KML files hosted on intranet sites we recommend that you render the KML on the client side by using third-party JavaScript libraries. As the KML file is analyzed by the browser, performance may be lower than by using the KmlLayer class.

What is the maximum number of markers or path vertices supported by the Maps Static API?

There is no limit to the number of markers or path vertices supported by the Maps Static API. When using custom icons, up to five unique icons can be specified per request, but each can be used multiple times within the map.

Note that Maps Static API URLs can contain a maximum of approximately 8,192 characters which constrains the number of markers and path vertices that can be specified based on the number of decimal places used when specifying each latitude/longitude pair. For information on how the number of decimal places used relates to the accuracy on the Earth see the Wikipedia article on Decimal Degrees.

Why can't I access Google Maps Platform products for certain countries?

Maps APIs may not be used in Prohibited Territories. Refer also to the Terms of Service.

How do I report a problem on the Google basemap?

Send feedback through Google Maps for wrong or missing map information such as:

Wrong addresses or marker locations
Incorrect road names
Wrong information about one-way and two-way roads
Incorrectly drawn road
Closed roads
Roads that don't exist

For correction of a place or business listing, suggest an edit.

If Maps content needs to be removed for legal reasons, submit a legal request.

For critical or time-sensitive requests, file a support case with specific details on what needs to be fixed.

How is performance monitored for the services used with Maps JavaScript API?

Some client-side features are instrumented to report success or failure for the purpose of calculating the SLO (Service Level Objective). This information is sent to Google at maps.googleapis.com/maps_api_js_slo/log in calls that log SLO information. This information includes success status, latency, and version/channel of the Maps JavaScript API in use. The calls may be batched for performance. Please note that you may need to allow maps.googleapis.com in your Content Security Policy to ensure these calls are not blocked at browser-level. For example: Content-Security-Policy: default-src 'self' maps.googleapis.com; with HTTP headers, or <meta http-equiv="Content-Security-Policy" content="default-src 'self' maps.googleapis.com;"> with HTML Meta Tags.

Maps JavaScript API

How long will the Maps JavaScript API work after it has been loaded?: You need to refresh the page that loads the Maps JavaScript API at least once every 5 days.

Google Maps SDK for iOS

How do I resolve the error: kGMSPlacesRateLimitExceeded?

If you are seeing this error, you may be using a deprecated version of the Places SDK for iOS. Version 2.7.0 of the Places SDK for iOS has been turned off, and is no longer available. Please update your app to use the latest version as soon as possible. See the migration guide for details.

I'm getting crashes when debugging with an iOS 8.x device. What should I do?

In XCode, choose Product, Scheme, Manage Schemes.
Select a scheme and choose Edit....
Set the GPU Frame Capture option to Disabled. Note that this option may not be present for all devices.

Xcode GPU Frame Capture option on the Generic iOS device page

What's the impact of rounded and wider screens on the Google Maps iOS SDK?

Beginning with the iPhone X, iPhones have a screen shape featuring rounded corners, a notch at the top for the device's sensor housing, and an indicator at the bottom of the screen for accessing the Home screen. As of iOS 11.0 SDK, Apple added the Safe Area API allowing developers to position elements in an area which is safe from being clipped by the new screen shape.

The Google Maps iOS SDK has many visual elements and controls, such as an indoor picker and the report a problem link. With version 2.4, these visual elements and controls could be clipped by the new screen shape. In landscape mode, the indoor floor picker may be clipped by either the notch or the home button indicator.

With the Google Maps iOS SDK 2.5 release these layout issues are fixed automatically. When your app is used on an iPhone X or later, the padding on GMSMapView and GMSPanoramaView are increased so that the visual elements aren't clipped.

By default, we will always include your padding. The Google Maps iOS SDK assumes that padding is intended to pad from within the safe area. If you design your interface with the assumption that everything is positioned within the safe area, this will work without any extra effort.

If you have designed an interface which doesn't work with our default adjustment, we have introduced a new property to GMSMapView, called paddingAdjustmentBehavior. GMSMapView now allows you to pick from one of three padding adjustments behaviors: 'Always' (default), 'Automatic', and 'Never'.

If GMSMapView is set to use the 'Always' padding behavior, it will always add the safe area insets to the padding. This allows you to design your interface with the assumption that all placement is from the edges of the safe area. This is the default value.

If GMSMapView is set to use the 'Automatic' padding behavior, it will always choose the larger of padding or safe area inset. This will allow you to add padding from the screen edge while always ensuring that all elements stay within the safe area.

If GMSMapView is set to use the 'Never' padding behavior, it will never add the safe area insets to the padding. This is the behavior prior to the 2.5 release and may be useful if your padding already takes into consideration the safe area, or if our other behaviors don't act well with your interface. It is your responsibility to ensure that the Google logo and copyright notices are always visible, as specified in the Google Maps Platform Terms of Service.

In contrast, GMSPanoramaView doesn't have an optional padding property. This means that there is no padding to adjust and GMSPanoramaView will always apply any necessary padding to ensure that all visual elements are within the safe area.

Google Maps SDK for Android

How do I resolve the error: 9005 PLACES_API_RATE_LIMIT_EXCEEDED?: If you are seeing this error, you may be using a deprecated version of the Places SDK for Android. The Google Play services version of the Places SDK for Android has been turned off, and is no longer available. Please update your app to use the latest version as soon as possible. See the migration guide for details.

My app only shows blank grey tiles instead of a map. How can I resolve this?

A common reason that a blank grey tiles are shown instead of a map is authentication issues. You can follow the steps below to troubleshoot those issues by using adb logcat.

Make sure you have adb installed. If not, you can follow the guide here.
Install the app that shows the problem on a device or an Android emulator. If you use Android emulator, make sure the emulator settings has Play Store included.
In Android Studio terminal, run adb logcat -e "Google Maps Android API". This will only print lines where the log message matches "Google Maps Android API" (Optionally, you can output the log to a text file by appending: > logcat.txt)
Reproduce the issue on your device and check for common errors such as:

The wrong/unintended API Key is being referenced in Manifest.
Billing isn’t enabled on Project.
The SDK isn’t enabled on project APIs.
The incorrect SHA1 fingerprint is added to the API Key restrictions.
The Google Play Service dependencies is not included in the build.gradle file.

URL signing

Can I sign URLs using JavaScript?

We strongly recommend against signing URLs using JavaScript as this would expose your URL signing secret to end users. Therefore signatures should only be generated by server side components.

Why am I receiving a HTTP 403 Forbidden response to my Maps API web service requests?

An HTTP 403 response indicates a permission issue, likely because the signature could not be verified for this request. This could be because:

A signature has been specified but is incorrect for this request.
The request specifies a Google Maps Platform Premium Plan an API key but does not specify a signature, and the service being called requires that requests made using an API key include a valid signature.
A signature has been specified but the associated Google Maps Platform Premium Plan API key has not been specified.
