Method: files.create

Uploads a file for use in media or rich card messages.

The agent provides the URL or binary of the file and (optionally) the URL of the corresponding thumbnail file. The RBM platform caches the file for 30 days and returns a unique name that you can use to identify the file when sending agent messages.

To upload a file binary, make an HTTP POST request to the Upload URI, omit the fileUrl field from the JSON request body, and specify the binary as the POST request body. For example, use the --upload-file cURL flag with the fully qualified file path of the binary file.

HTTP request

  • Upload URI, for media upload requests:
    POST https://rcsbusinessmessaging.googleapis.com/upload/v1/files
  • Metadata URI, for metadata-only requests:
    POST https://rcsbusinessmessaging.googleapis.com/v1/files

The URL uses gRPC Transcoding syntax.
