SMS Backup

  1. Updates on the status of this message are sent to the callback URL for your Transaction Callback Service. The general callback schema common to both this and other products is described on Transaction Callback Service. Modifications to the callback schema for this product are described on Messaging - Callback service. Search for these callbacks based on the reference ID in the response to your original Messaging request. Each callback payload includes an object with the status of the send for each channel that is tried.

Callback example
