## 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 ` | ` https://protobuf.dev/reference/protobuf/google.protobuf#any ` 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. |
| ` 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. |
| 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 ` can be set. Some services might not provide the result. ` result ` can be only one of the following: ||
| ` error ` | ` https://developers.google.com/merchant/api/reference/rpc/google.rpc/Types/Status ` The error result of the operation in case of failure or cancellation. |
| ` response ` | ` https://protobuf.dev/reference/protobuf/google.protobuf#any ` 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 ` . |
