Proceed in almost the same way as for a SOAP web service.
Note that there are some major differences between configuring with the SOAP & REST web service approach:
- In REST, you do not have WSDL (actually did some reading around to know this).
- You have to add your "Operations" yourself since there is no WSDL to import from. The Operation you create is what you eventually use in Rules.
- Just like all other entities, when sending a POST request (to create an entity), you have to add "type" as one of the Operation's variables. This would be used to specify the bundle type (i.e article) to the web service.
