This particular client uses PP Standard but I will encourage them to move towards the Pro account. But in the mean time, if I were to continue with the Standard setup, please tell me if I have the workflow correct.
With a PayPal Standard account using the IPN, the checkout process would be the same as usual, (Products page > Shopping Cart Page > Checkout page > Confirm page > PayPal site).
...then following the completion of the PayPal payment, they would be sent to the "Thank You" page back at the site, and at the same time a notification would be sent to a separate hidden page (IPN).
That IPN page would then have some kind of Update behavior on it that would mark the item's table column for Status as "Sold"? Is that a correct summary?
If this is correct, do I simply use the sample IPN code that PayPal has for PHP on their site as a starting point and then add the recordset and Update behavior?
I know that within the PayPal account their is a location for me to enter the URL for the IPN page once I create it, but do I also need to include any information back at the checkout form for this part?
