HTTP request

PATCH https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/reservations/{reservation}

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.
`zone`	`string` Name of the zone for this request.
`reservation`	`string` Name of the reservation to update.

project

string

Project ID for this request.

zone

string

Name of the zone for this request.

reservation

string

Name of the reservation to update.

Query parameters

Parameters

Parameters
`requestId`	`string` An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported (`00000000-0000-0000-0000-000000000000`).

requestId

string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

Response body

Represents an Operation resource.

Google Compute Engine has three Operation resources:

You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.

Operations can be global, regional or zonal.

For global operations, use the globalOperations resource.
For regional operations, use the regionOperations resource.
For zonal operations, use the zoneOperations resource.

For more information, read Global, Regional, and Zonal Resources.

Note that completed Operation resources have a limited retention period.

If successful, the response body contains data with the following structure:

`warnings[]`	`object` [Output Only] If warning messages are generated during processing of the operation, this field will be populated.
`warnings[].code`	`enum` [Output Only] A warning code, if applicable. For example, Compute Engine returns `NO_RESULTS_ON_PAGE` if there are no results in the response.
`warnings[].message`	`string` [Output Only] A human-readable description of the warning code.
`warnings[].data[]`	`object` [Output Only] Metadata about this warning in `key: value` format. For example: "data": [ { "key": "scope", "value": "zones/us-east1-d" }
`warnings[].data[].key`	`string` [Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be `scope` and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
`warnings[].data[].value`	`string` [Output Only] A warning data value corresponding to the key.
`httpErrorStatusCode`	`integer` [Output Only] If the operation fails, this field contains the HTTP error status code that was returned. For example, a `404` means the resource was not found.
`httpErrorMessage`	`string` [Output Only] If the operation fails, this field contains the HTTP error message that was returned, such as `NOT FOUND`.
`selfLink`	`string` [Output Only] Server-defined URL for the resource.
`region`	`string` [Output Only] The URL of the region where the operation resides. Only applicable when performing regional operations.
`description`	`string` [Output Only] A textual description of the operation, which is set when the operation is created.
