Stay organized with collections Save and categorize content based on your preferences.

Get the RBM-related capabilities of a user.

The returned payload specifies whether a user can be reached with RBM and, if so, which RBM features the user supports. If the user can't be reached with RBM, the RBM platform returns 404 NOT_FOUND.

An agent that isn't launched can only request capabilities for users who are testers of that agent. If an unlaunched agent requests the capabilities of a non-tester, the RBM platform returns 403 PERMISSION_DENIED.

HTTP request

GET https://rcsbusinessmessaging.googleapis.com/v1/{name=phones/*}/capabilities

The URL uses gRPC Transcoding syntax.

Path parameters



This field resolves to "phones/{E.164}/capabilities", where {E.164} is the user's phone number in E.164 format. For example, for a user with the US phone number +1-222-333-4444, the resulting endpoint is https://rcsbusinessmessaging.googleapis.com/v1/phones/+12223334444/capabilities.

Query parameters



The unique ID of the request, assigned by the agent. This must be a UUID, as defined in https://tools.ietf.org/html/rfc4122. If the request ID matches an ID that the agent used for a previous request, the RBM platform ignores the new request.
