Welcome to the second in a two part series on understanding the messaging API callbacks. In our first post we covered using postman and setting up to handle the message callback. If you haven’t yet read the first post you can check that out at Understanding Messaging API Callbacks - Part 1.

The callback functionality of the messaging API is a great utility allowing you to track the delivery status of sent messages, and receive replies to your dedicated phone number without the need of making additional API calls.

In this first of 2-post series, I will walk through how to set up callbacks for your app and how to develop and test callback features without having a hosted endpoint.
