I am totally lost, as I am totally new to this. I am trying to integrate HSBC as payments gateway to my plantperfection.co.uk site.

HSBC Have sent the following 2 files to me (I have uploaded them to the internet so you could see if they make sense to you):

APIOverview.pdf
&
http://skyegospel.co.uk/XML_API_Interface_Ref.pdf

I am just totally at a loss to know what to do with this info! I don't know if I am to make up files, or get them from somewhere else, and where I am to put them or what I am to do with them after.

If anyone could jsut point me really simply in the right direction I would be very, very grateful!

Stuart
