Getting repeated calls on facebook-messenger webhook

Question

I have successfully setup a facebook-messenger webhook. Until yesterday I was able to send and receive messages as well. But today, when I am sending one message from user, I am getting multiple calls at server webhook POST API. They never seem to stop.

Answer 1

Do all of those calls have the same content or are they different? You could log the exact message string that facebook sends to you and see what they include.

For example there's a message delivery callback that informs you that the user received the message. The JSON looks like this:

{'delivery': {'mids': ['mid.146174459xxx:30a42600a95exxxxx'], 'seq': 429, 'watermark': 146174459xxx}, 'recipient': {'id': xxxxxxxx}, 'sender': {'id': xxxxxx}}

Edit: It could also be the case that your are not confirming incoming calls with a http status 200. If facebook receives an error from your webhook the message will be sent multiple times.
