REST Resource: projects.operations

  • An Operation resource represents a long-running operation resulting from a network API call.

  • An Operation has fields for its name, service-specific metadata, and a boolean done indicating completion.

  • Upon completion (done is true), an Operation will have either an error or a response field set.

  • Operations can be managed using methods like cancel, delete, get, list, and wait.

Resource: Operation

This resource represents a long-running operation that is the result of a network API call.

Fields
name

string

The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id}.
metadata

object

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.
done

boolean

If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.
The operation result, which can be either an error or a valid response. If done == false, neither error nor response is set. If done == true, exactly one of error or response can be set. Some services might not provide the result. The following is a list of mutually exclusive fields. At most one of the fields will be set in a response:
error

object (Status)

The error result of the operation in case of failure or cancellation.
response

object

The normal, successful response of the operation. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse, where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.
End of mutually exclusive fields.

Methods

cancel

 Starts asynchronous cancellation on a long-running operation.

delete

 Deletes a long-running operation.

get

 Gets the latest state of a long-running operation.

list

 Lists operations that match the specified filter in the request.

wait

 Waits until the specified long-running operation is done or reaches at most a specified timeout, returning the latest state.
