I need to intergrating HSBC API payment system into my Shopping Cart. The cart is American and does not support Switch/Solo and other debit Cards so extra fields will need to be added to the cart's credit card entry page (which is in php), so we can collect the customer's issue number and card start date. I have got the HSBC API account set up and working at the Bank end so it's ready to be worked on ASAP. Previous experiance with php Shopping Carts is important as HSBC do not give any intergration information apart from in XML, so this will have to be converted to work with php. There is already PayPal Pro API set up and working as an option on the cart so we know the cart can work with API, we just want to add another gateway file for HSBC.
