Postback (Web Callback, HTTP Push API, or Reverse API) is one way one web application can send information to another application in real-time when a specific event happens.


If you have subscribed to the itr.efiled webhook event, you will receive a notification every time your ITR is filed.

Postback Vs. API

APIs send you the data when you request it. For Postback, you do not need to make a request. You receive the data when it is available.


If you need to know whether an ITR is filed or not, using APIs you need to keep polling every few seconds until it gets efiled. While if you are using Postback, you can configure a postback event itr.efiled to receive notifications when your ITR is efiled.

Postback Configuration events can be set by sending an API request and pointing out the events for which you would like to receive a Postback.
