Enterprise License Manager API: Developer's Guide

This document describes how account-level and reseller administrators can use the Enterprise License Manager API to manage users license assignments. Once your account's product SKU licenses have been enabled and your users have been created, use the Enterprise License Manager API to assign, update, retrieve, and delete licenses for your account's users.

In this version, the Enterprise License Manager API is used by account and reseller administrators. Delegated administrators with the License Management privilege can also use the Enterprise License Manager API.

Note: The Enterprise License Manager API is used by a Google customer. For information about how Google third-party application developers manage licenses, see the Google Workspace Marketplace API.

The Enterprise License Manager API is based on the Representational State Transfer (RESTful) design approach to web services.

Managing Licenses

Assign a license

Previous to this operation, the customer or reseller has ordered Google product licenses and has created the user. To assign one of these product licenses to this user, use the following POST HTTP request. Include the Authorization header as described in Authorizing requests. For product and SKU IDs, see the API's available Products and SKUs:

POST https://www.googleapis.com/apps/licensing/v1/product/productId/sku/skuId/user

Note: A user can be assigned licenses for a wide range of different Google products. But a user is assigned only one SKU license per product at a time. By using the API, a user's SKU license can be reassigned to a different SKU license within the product.

This example assigns the Google-Drive-storage-20GB SKU to the user whose primary email address is [email protected]:

POST https://www.googleapis.com/apps/licensing/v1/product/Google-Drive-storage/sku/Google-Drive-storage-20GB/user

The JSON request body:

{
  "userId" : "[email protected]",
}

A successful response returns a 200 HTTP status code. For possible error codes, see the API's Error codes. If successful, the response returns the licensing assignment status in JSON data format.

JSON Response

{
  "kind": "licensing#licenseAssignment",
  "etags": "etag value",
  "selfLink": "https://www.googleapis.com/apps/licensing/v1/product/Google-Drive-storage/sku/Google-Drive-storage-20GB/user/[email protected]",
  "userId": "[email protected]",
  "productId": "Google-Drive-storage",
  "skuId": "Google-Drive-storage-20GB",
  "skuName": "Google Drive storage 20 GB",
  "productName": "Google Drive storage"
}

For more information, see the licenseAssignments insert method reference page.

Reassign a user's product SKU with a different SKU in the same product

To reassign a user's license to a new license SKU within the same product, use the following PUT HTTP request. The API also supports the patch syntax. Include the Authorization header as described in Authorizing requests. For product and SKU IDs, see the API's available Products and SKUs:

PUT https://www.googleapis.com/apps/licensing/v1/product/productId/sku/the current skuId/user/user's email

This example updates the present Google-Drive-storage-20GB SKU with the Google-Drive-storage-50GB. The present license SKU is in the request's URI and the new license SKU is in the request's body:

PUT https://www.googleapis.com/apps/licensing/v1/product/Google-Drive-storage/sku/Google-Drive-storage-20GB/user/[email protected]

The JSON request body has :

{
  "kind": "licensing#licenseAssignment",
  "etags": "etag value",
  "selfLink": "https://www.googleapis.com/apps/licensing/v1/product/Google-Drive-storage/sku/Google-Drive-storage-50GB/user/[email protected]",
  "userId": "[email protected]",
  "productId": "Google-Drive-storage",
  "skuId": "Google-Drive-storage-50GB",
  "skuName": "Google Drive storage 50 GB",
  "productName": "Google Drive storage"
}

A successful response returns a 200 HTTP status code. For possible error codes, see the API's Error codes. If successful, the response returns the license assignment status in JSON data format.

JSON Response

{
  "kind": "licensing#licenseAssignment",
  "etags": "etag value",
  "selfLink": "https://www.googleapis.com/apps/licensing/v1/product/Google-Drive-storage/sku/Google-Drive-storage-50GB/user/[email protected]",
  "userId": "[email protected]",
  "productId": "Google-Drive-storage",
  "skuId": "Google-Drive-storage-50GB",
  "skuName": "Google Drive storage 50 GB",
  "productName": "Google Drive storage"
}

For more information, see the licenseAssignments update method and patch method reference pages.

Retrieve all users assigned licenses for a specific product

To get all user licenses for a specific product, use the following GET HTTP request. Include the Authorization header as described in Authorizing requests. The customerId query string is the customer's primary domain name. The maxResults query string determines how many user license entries are returned in the API's response:

GET https://www.googleapis.com/apps/licensing/v1/product/productId/users?customerId=primary domain name&maxResults=max results per page

For product and SKU IDs, see the API's available Products and SKUs.

This example lists the first page of results for all users in the example.com domain assigned licenses for the Google-Drive-storage product:

GET https://www.googleapis.com/apps/licensing/v1/product/Google-Drive-storage/users?customerId=example.com&maxResults=2

A successful response returns a 200 HTTP status code. For possible error codes, see the API's Error codes. If successful, the response returns the licensing list in JSON format.

JSON Response

{
  "kind" : "licensing#licenseAssignmentList",
  "etag": "etag value",
  "nextPageToken" : "the next page token value",
  "items": [
  {
    "kind": "licensing#licenseAssignment",
    "etags": "etag value",
    "selfLink": "https://www.googleapis.com/apps/licensing/v1/product/Google-Drive-storage/sku/Google-Drive-storage-50GB/user/[email protected]",
    "userId": "[email protected]",
    "productId": "Google-Drive-storage",
    "skuId": "Google-Drive-storage-50GB",
    "skuName": "Google Drive storage 50 GB",

    "userId": "[email protected]",
    "productId": "Google-Drive-storage",
    "skuId": "Google-Drive-storage-200GB",
