Hi Xavier,
I thought setting the 'Return URL' in the PayPal Standard plugin would do it but it does not.
Here is what I have done:
1. In Hika: See PayPal plugin settings on HikaPPSettings.png
2. In PayPal (sandbox) on Seller acount: Enabled Instant Payment Notifications and entered the same URL as I did in the Hika PayPal plugin - see ipnPPSettings.png
3. White-listed all of the IP addresses listed in the Hika PayPal plugin
4. Submit a purchase, I am in fact returned to the Return URL that I entered in the PayPal plug in, however I do not see any of the URL parameters passed - the location I am being returned to is my own servlet that reads parameters passed to it and writes them to a log - I can confirm nothing was passed by the absence of PayPal IPN data in the logs I write to
5. Also, I can tell PayPal is using a different URL for IPN notifications, see ipnHistory.png, the Notification URL is the Hika Store, rather than the URL I entered in the PayPal plugin and in the PayPal IPN settings
So, what I'm looking for is to override the Notification URL as see in ipnHistory.png with my URL. Is this a mod to one or more .php file? If so, what would that mod look like?
Thanks,
-Mike
