REST Resource: operations

Resource: Operation

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

JSON representation
{
  "name": string,
  "metadata": {
    "@type": string,
    field1: ...,
    ...
  },
  "done": boolean,

  // Union field result can be only one of the following:
  "error": {
    object (Status)
  },
  "response": {
    "@type": string,
    field1: ...,

  }
  // End of list of possible types for union field result.
}
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

This field will contain a DevicesLongRunningOperationMetadata object if the operation is created by claimAsync, unclaimAsync, or updateMetadataAsync.

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.

Union field result. 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 is set. result can be only one of the following:
error

object (Status)

This field will always be not set if the operation is created by claimAsync, unclaimAsync, or updateMetadataAsync. In this case, error information for each device is set in response.perDeviceStatus.result.status.

response

object

This field will contain a DevicesLongRunningOperationResponse object if the operation is created by claimAsync, unclaimAsync, or updateMetadataAsync.

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" }.

Status

The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC. Each Status message contains three pieces of data: error code, error message, and error details.

You can find out more about this error model and how to work with it in the API Design Guide.

Fields
code

integer

The status code, which should be an enum value of google.rpc.Code.

details[]

object

A list of messages that carry the error details. There is a common set of message types for APIs to use.

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" }.

Methods
