## Remarks

- Requires the same vault session that received the request.
- `id` must be the `response_id` of a request that the server is still waiting for. Any other
  ID, including 0, an ID of a notification, or an ID whose wait has timed out, fails with "The
  parameter is incorrect. (<id>)".
- Has the same effect as [SendPushDataResponse](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCVault/SendPushDataResponse/index.md).

- [IRPCVault.SendPushDataResponse](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCVault/SendPushDataResponse/index.md): Sends a response for server data push. This is a response for request received with RequestPushDataAsync call (with non-zero request id). This call completes the push data cycle.
