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.
