Hi, I've posted this question on the oscommerce forum but there nobody genuinely wants to help me. I feel they want me to hire their services for a fee. So I'm posting it here on the chance someone could genuinely help me. I'm using oscommerce 2.3.1 The payment module I'm using is PayPal Website Payments Standard. My paypal account is Premier account. Could someone let me know the step by step process I should use to configure Paypal with oscommerce, especially the API access inside My Selling Preferences and what to do with IPN. What bits of information do I have to get from my Paypal account and what should I do with these in oscommerce? I would be very grateful for all help.
The paypal standard is not IPN. If you want to do instant payment notifications you need a separate module and it's not included in the vanilla osc but there are contributions for it. The stock version uses now the paypal express where a token is generated once the customer logs in to his account and then returns to your store.
Also each of the paypal modules has different configuration switches that change some parameters passed to paypal. As of the paypal control panel you don't need to do anything there for IPN, other than knowing your email address or pal-id. Because these parameters with IPN (whether to auto return to the store etc) can be controlled via the module's code.
