Use REST Services

REST is an acronym of Representational State Transfer, and is the practise of building services using the semantics of the web.

A REST service request can be defined using four parameters:

• A URL which identifies the resource (for example: the learner or course)
• A verb which identifies the operation
• A message body which contains information about the operation being performed
• A collection of headers which contain miscellaneous data that the service may require

A REST service response can be defined using three parameters:

• A status code summarising the outcome of the request (for example: an error of 404 for not found)
• A body containing detail of the service response (that is: the data requested)
• A collection of headers which contain miscellaneous information about the response
