Postbacks

Set up postbacks to receive notification whenever text messages are sent, received, or updated. The SMS Notify! API will automatically post information to a URL that you specify.

We recommend that you store the postback data in a database, so that you can refer to them later.

Set Up a Postback URL

To use postbacks you will need to set up and host your own URL or URLs to handle them. Use the following API methods.

• Specify a postback URL with the SetPostbackUrlForLicenseKey or SetPostbackUrlForPhoneNumber method.
• Enable/disable postbacks with the SetPostbackEnabledForLicenseKey or SetPostbackEnabledForPhoneNumber method.
• Specify a postback URL when sending a message with SendMessage.

Types of Postbacks

Esendex sends three types of postbacks.

1. Outgoing postbacks: SMS Sent and MMS Sent
2. Incoming postbacks: SMS Response and MMS Response
3. Delivery postbacks: SMS Delivery Receipt and MMS Delivery Receipt
