Why do we need IPN when PayPal send instant noticeAsked by ingrdo on June 08, 2014 at 05:39 PM
Why do we need to do this when Jotform and PayPal send instant notification already? I don't know what any of this means, really, except that, as far as I know, I don't have an url to send anything to, and this will terminate my relationship with jotform.
This is a re-post of a comment on How to Enable IPN on your Paypal Account
I suggest reviewing also this article
It should help get a better understanding about the Paypal IPN and its purpose on the payment form.
Here is an excerpt from the article that explains it more
Sending IPN to a custom URL for JotForm-initiated transactions
There are times when you want to send the IPN data to your own URL, perhaps for data processing, but you also do not want JotForm and Paypal integration to break.
This is where IPN Relay comes into play. The IPN message reaches our server first, then, if an IPN Relay URL is set, JotForm relays the message to that URL.
To set an IPN Relay URL, right-click on your Paypal field then click Show Properties. Enter your preferred URL on the field.
