Catapult API oAuth Integration

Catapult eLearning system brings together the key aspects of online training: An extensive library of Vocation Education and Training (VET) training and assessment support resources within a learning management system (LMS). Catapult provide eLearning content through SCORM objects they host.

As part of providing these SCORM objects each user enrolled in the host LMS (the LMS calling the Catapult content) must also be manually enrolled in the Catapult hosted LMS for the organisation. From an automation point of view, this is not ideal.

 Catapult provide a basic API through REST, returning JSON, that allows for enrolments to be created and queried. A CFC was required that provides functions to call this API, i.e. a gateway/proxy/wrapper.

The cfc we created has two methods corresponding to REST GET and POST actions and appropriate oAuth related code to sign our requests.
