A request message sent as part of a batch execution.

| JSON representation |
|---|
| ``` { "requestId": string, "methodName": string, "request": { "@type": string, field1: ..., ... }, "extensions": [ { "@type": string, field1: ..., ... } ] } ``` |

| Fields ||
|---|---|
| `requestId` | `string` Unique id of this request within the batch. The Response message with a matching `requestId` is the response to this request. For request-streaming methods, the same `requestId` may be used multiple times to pass all request messages that are part of a single method. For response-streaming methods, the same `requestId` may show up in multiple Response messages. |
| `methodName` | `string` The method being called. Must be a fully qualified method name. Example: google.rpc.batch.Batch.Execute |
| `request` | `object` The request payload. 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" }`. |
| `extensions[]` | `object` Application specific request metadata. 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" }`. |
