PayPal IPN Verification Postback to HTTPS

Hello Dan

Yes. I can confirm that if it works OK now, it should continue working fine. I guess PayPal not only notify you, they are notifying everyone uses PayPal payment system

Hi Tuan --

Thanks again for your reply. I'm sorry to continue to question this, but I am still confused on exactly what occurred with this issue. This is very important and could cause severe problems for my site so I just want to understand what happened. Could you please explain what happened with this from your original reply last year in that other thread versus what you are saying now? So did you think one thing last year when you said all extensions would need updated, and then looked at it again now this year and determined nothing needed done?

I was wrong about the Postback to HTTPS. Now, I looked at it again and confirm that there is no change needed

However, if you are using old version of Membership Pro, there might be some case, payment is made but subscription is not update automatically to Active.

That's because PayPal, sometime, sends IPN message to wrong URL (it just send to domain.com/index.php?option=com_osmembership instead of domain.com/index.php?option=com_osmember...task=payment_confirm as requested by Membership Pro)

It sometime happens (look like a bug in PayPal system somehow) and we addressed it before by adding some code to Membership Pro

That's why I said before that if it is working OK now on your site, it will continue working well

Tuan

Ok sounds good, thanks so much for explaining. I was aware of the other weird PayPal IPN issue you mentioned, I'm pretty sure I have not seen that happen with my site, which is good.

There is something else I wanted to ask about for IPN. I have noticed on many posts your comment about IPN that it needs to be set to "enabled" in the PayPal account. Mine is set to "disabled", however my site works ok - I get payment and a subscription is created in MP like normal. However, I noticed if I login to my PayPal account and then open a new tab and go directly to the URL www.paypal.com/cgi-bin/webscr?cmd=_display-ipns-history , that page does show a history of IPN messages sent for my account. I just thought this behavior was odd and wondered if you have seen this? You can see in my attached screenshot at the top it says "disabled", yet shows an IPN history.
