The MMS MO / SMS MO Postback API notifies you that a customer has replied to your message, or interacted to one of your keywords. To receive SMS MO postback notifications you need to have that option enabled in your account API. You can setup a separate Postback URL specifically for SMS/MMS MO’s.
Once enabled you will receive an notification immediately when someone interacts with your shared shortcode campaign or your dedicated shortcode. Each message comes back in its own postback notification.
To receive MMS MO postback you need to configure it within the particular MMS Inbox keyword campaign. Once the MMS MO postback is enabled in the MMS Inbox campaign you will start receiving postbacks for each MMS MO received on the MMS MO Keyword or replies to an SMS sent. If you have opted to enable the MMS MO moderation panel, then the postback notifications will only be sent upon approval by the moderator.
This postback notifies you when an SMS MO is received.
