I know that IPN can send same transaction to my listener until I acknowledge it. I was wondering about implementing webhooks instead of IPN. but I am not sure that webhooks will keep sending events to my listener for the same transaction until I acknowledge it.
It might happen that when payment happened on a client-side, and event got sent to my server, my database call got failed or my server was down. How do I make sure that webhook can send it to me again and again until I acknowledge it ? is it possible?
