Method: routers.patch

Patches the specified Router resource with the data included in the request. This method supports PATCH semantics and uses JSON merge patch format and processing rules.

HTTP request

PATCH https://compute.googleapis.com/compute/v1/projects/{project}/regions/{region}/routers/{resourceId}

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
region

string

Name of the region for this request.
resourceId

string

Name of the Router resource to patch.

Query 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).
