Starts asynchronous cancellation on a long-running operation. The server
makes a best effort to cancel the operation, but success is not
guaranteed. If the server doesn't support this method, it returns
google.rpc.Code.UNIMPLEMENTED. Clients can use Operations.GetOperation
or other methods to check whether the cancellation succeeded or whether
the operation completed despite cancellation. On successful
cancellation, the operation is not deleted; instead, it becomes an
operation with an Operation.error value with a google.rpc.Status.code of
1, corresponding to Code.CANCELLED.
Arguments
Parameters
name
string
Required. The name of the operation resource to be cancelled.
region
string
Required. Region of the HTTP endpoint. For example, if region is set to us-central1, the endpoint https://us-central1-integrations.googleapis.com will be used. See service endpoints.
Raised exceptions
Exceptions
ConnectionError
In case of a network problem (such as DNS failure or refused connection).
HttpError
If the response status is >= 400 (excluding 429 and 503).
TimeoutError
If a long-running operation takes longer to finish than the specified timeout limit.
TypeError
If an operation or function receives an argument of the wrong type.
ValueError
If an operation or function receives an argument of the right type but an inappropriate value. For example, a negative timeout.
Response
If successful, the response will be empty.
