I am trying to do something in zen cart that uses a third part API so that I can get some quotes.

The documentation says for customers to use these APIs via HTTP GET over SSL (Secure Sockets Layer) protocol so as to protect the API keys. The required design pattern is for customers to use AUTH-KEY and SSL for both the production and non-production websites. The API keys cannot be used in address line calls and MUST be sent within the HTTP HEADERS. Any ideas on how to do this using curl?

Curl needs to be used to send the above, and pass the parameters.

The response will be in xml format, so I will need to strip the xml and just use the values, unless I can use xml in the modules page. Any ideas on how to do this?

Thanks for any replies.
