Hi there,

I’m having problems with WPSC where the customer is returned automatically (by PayPal) to a different URL than I’ve passed to PayPal. This is for a recurring billing product (so the Gold Cart and Membership upgrades are installed). Everything is up-to-date.

The Transaction Results page gives me the same error as a number of others have received “Sorry your transaction was not accepted.”, even though the transaction was successful. From a quick look at the debug page, I’ve come up with the link sent to PayPal (as the ‘return’ variable):

Return Variable (the link WPSC sent to PayPal):
http://denaliguide.us/products-page/transaction-results/?sessionid=9911300561883&gateway=paypal
(this looks okay – it has the sessionid and gateway variables)

Here’s the URL actually returned by PayPal, as seen in my browser URL bar:
http://denaliguide.us/products-page/transaction-results/?auth=XJpMtqCyZNLzWz1NHSt5AkH9fLxn6r8Vl84op6mHNLoUVCkbjffU7ocbC4eShSJmKsOVmnEZ-1Zjw2DHGx6pMem_cRNwwDTK_wsWmFT9vEzONO8zqIgCDM31o7ToyZD076lqfJdWfVkwRg0gV36DtFEllS4u8qfYkj5DfR4GsEZzjis2OjNVu9st-4SZGzIkeEmgmk41IEXvLn1fUWqdTrrOh8ouptjORuKdlW&form_charset=UTF-8
(no longer has the variables passed to PayPal via the form)

…later I added the sessionid variable (manually typing it in the URL bar – at the end of the URL), and it worked perfectly, displaying the information on the purchase as it should.

So here’s the issue, as I see it:
– WPSC sent a properly formatted return URL to PayPal
– PayPal took the URL and for whatever reason stripped all variables, then added its own variables (sessionid, form_charset)
– this wasn’t recognized by WPSC when it came back to the /transaction-results/ page.
– it made me stay up quite late on Friday

Can anyone explain why this is happening?

Cheers,
Graham

As you don’t mention BuddyPress, and that this problem seems to be limited to WP e-Commerce, you’ll need to talk to Instinct to understand if it’s a WP e-Commerce PayPal library problem or something with PayPal itself.

Awesome. Sorry about that, Paul… I spent enough time thinking through my response but clearly didn’t think enough about the forum in which it should have been posting.

Thanks!
