Set up postbacks to receive notification whenever text messages are sent, received, or updated. The SMS 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.

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

Let’s start sending, together.
