Integrate XML API code in Classic ASP website for a HSBC payment gateway integration

I have a website开发者_如何学Go which is having paypal integration (all using classic ASP).

Now we need to remove Paypal and integrate the HSBC gateway using XML API. I need to know how to integrate the XML code in classic ASP from scratch.

Take a look at this MSDN entry for a beginner's tutorial for working with XML.

Then take a look at this MSDN article for API documentation.

Other source on StackOverflow: Asp XML Parsing

Depending on the requirements of HSBC you can then build XML requests and parse XML responses. If HSBC is offering a SOAP service then the following resource might be handy:
