I need this information to continue testing and implementing
I am not sure how the forum works as I have not had a need to use it. I do now.
In the above post I may not have been clear enough as to the issue. I can make the sandbox work. I have put the correct credentials in the files pp_confirm.php and checkout.php. The file confirm.php does not use the same information and I would really appreciate knowing what information to use. In the first two they use user, vendor and pwd which are the credentials provided by Paypal both for the sandbox and live system. In confirm.php it uses user, vendor, partner and pwd which are not provided as part of the paypal credentials. Does anyone have this information?
