I'm brand new to setting up IPN's. I've built websites, but never a subscription site like the one I'm building now. I'd like to set up a recurring monthly subscription option and a recurring yearly subscription option.
My website is built on Joomla 3 and I'm using a plugin for the subscription module. I set up the PayPal subscription buttons just as explained in the directions, which I followed to the letter. Nevertheless, when I go to test it in the PayPal sandbox, I keep getting the same error, which says that it wasn't sent and the handshake wasn't made, and to check my settings. That's all it says. I don't know if the issue is with my site, my server or the settings I'm entering into the actual sandbox. I checked with my server and they said there's nothing wrong on their end. Do I need an SSL for the integration to work?
Please keep in mind that, while I can follow explicit directions, I'm so new at this that I don't even know how to access my 'listener,' so if you respond, please let me know where to find things, if necessary.
Any help would be very greatly appreciated - I've been at this for 12 hours now and I'm at a complete loss.
