Hello all
I have a chronoform with an IPN listener in an ipn event and I noticed in the last year or so that there are cases when the IPN is not received by the listener.
It did not cause a huge issue because only a few messages were lost and I was able to just use the paypal email notifying me of the payment. But now the instances in which this happen are increasing.
So I did some research and came across the following:
PayPal is trimming / removing the query strings in the notify_url parameter, which is used for receiving the IPN notification from PayPal.

Has anyone faced the same issue and how did you resolve it?
Thank you
Kind regards
Amelia

Hi Amelia,

Looking at the J2Store post I think that it might work if you create a hidden menu item on your site for the form ipn event. You can then add the query string to identify the form and event to the menu item and just send PayPal a Notify URL something like https;//my_domain.com/ipn_aaa
