Ok, so. I have site "a" which offers digital downloads upon successful payment. This site handles all of our digital product deliveries. I also have Site "b" which offers services that before when customer returns to the site would be redirected to our details page for the given service that was ordered on site "b" I would like to add site "c" - "z" that all require a notification to be sent to the script upon payment. Now, my question is. Site "a" required me to set auto return to on and to enter the notify url. This is screwing with site "b" sales, as when a customer makes a purchase on any of my other sites they are sent to the notification url that was entered into my paypal account for site "a" which has nothing to do with what was purchased on site "b". Is there a fix for this or am I just missing something that would allow me to overwrite the auto return for site "a" for the other sites? Thanks for reading and for any help anyone can offer on this.
I think the return parameter you can pass from your script only. In the script you need to mention the return URL and that will be passed to paypal and upon completion of payment customer will return to that URL. I think that's it !!
