Opt-in Status Postback

The Opt-in Postback API notifies you of an opt-in or opt-out status change for each number subscribed to your campaigns.

Mobile Subscribe

This postback notification triggers when a mobile phone number subscribes to a specific campaign. We send the notification again even if someone who is already opted-in triggers the opt-in process a second time.
