RCSWebhooks

Fallback exhausted

Final notification of an SMS fallback chain: the backup SMS also failed, or it could not be generated. After this event the chain is over — no automatic retry follows.

Unlike the four RCS event types, this event is not wrapped in the RCS envelope: it is a plain JSON body. When the backup SMS failed, message_id is the identifier of the backup SMS and origin_identifier points back to the original RCS message_id.

Note: while the backup SMS is alive, its regular status events (SENT and the SMS error statuses) arrive as SMS webhooks (see the SMS API documentation) carrying origin_identifier to correlate them with the RCS send.
