I have recently registered with Alertpay and want to integrate into our shopping cart using the Advanced Integration Method and IPN.
Data for the items we sell must continue to be held on our site as prices vary depending on special discounts offered, discount codes used by our customers, etc.
As such, we want to pass the total customer transaction value to Alertpay for processing (without reference to the individual items sold).
In this case, am I right in saying that:
1. We do NOT need to set anything up (in terms of ADD AN ITEM) in the Alertpay control panel, and
2. All we need to do for each transaction is pass:
ap_purchase_type = anystring,
ap_merchant = our email address,
ap_quantity = 1,
ap_amount = total value to be charged to card,
ap_currency = 'USD'
This would seem logical from reading the Integration Guide, but I just wanted to confirm before getting the code written.
Many Thanks.
