An Operation resource. For more information, see [Operation](../../../../../api-design-guide/concepts/operation.md).

#|
||Field | Description ||
|| id | **string**

ID of the operation. ||

Description of the operation. 0-256 characters long. ||
|| created_at | **[google.protobuf.Timestamp](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#timestamp)**

Creation timestamp. ||

|| modified_at | **[google.protobuf.Timestamp](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#timestamp)**

The time when the Operation resource was last modified. ||
|| done | **bool**

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. ||
|| metadata | **[google.protobuf.Any](https://developers.google.com/protocol-buffers/docs/proto3#any)**

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any. ||
|| error | **[google.rpc.Status](https://cloud.google.com/tasks/docs/reference/rpc/google.rpc#status)**

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

Includes only one of the fields `error`, `response`.

The operation result.
If `done == false` and there was no failure detected, neither `error` nor `response` is set.
If `done == false` and there was a failure detected, `error` is set.
If `done == true`, exactly one of `error` or `response` is set. ||
|| response | **[google.protobuf.Any](https://developers.google.com/protocol-buffers/docs/proto3#any)**

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is [google.protobuf.Empty](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#google.protobuf.Empty).
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields `error`, `response`.

The operation result.
If `done == false` and there was no failure detected, neither `error` nor `response` is set.
