We have an OSCommerce store which currently uses HSBC's CPI gateway to process payments. We would like to change this and use HSBC's API instead. This allows us to keep the customer on our site for the duration of the transaction. Our site is hosted on a Linux server, with PHP version 4.4.3. Any other info required just post a message and i'll respond.
Please only post if you have integrated HSBC API into a website before and please provide links to any websites that you have worked on that feature the HSBC API. Thanks
