I had to rewrite our product shopping cart a few years ago and the decision was made to use PayPal as our payment processing service. I cobbled together a Merchant API using NVP and have successfully used it for all payment processing. Our business model is now changing to a Membership service (we sell online training for a medical procedure). I need to blend our shopping cart to continue to offer products but also allow Membership subscriptions.
How can I pass on through the API the difference between a product order and a membership subscription so that PayPal will setup a subscription instead of just treating it like a product sale?
I need to use the API instead of PayPal buttons. I need the payment success response from PayPal to complete sales processing on our end. I can't tell if the PayPal "buttons" provide this but it doesn't appear to.
Thanks for any help on this,
George
