How to Define REST Interfaces in InterSystems IRIS
There are two ways to define REST interfaces in InterSystems IRIS:
Define an OpenAPI 2.0 specification and then use the API Management tools to generate the code for the REST interface.
Manually code the REST interface, then define a web application in the Management Portal.
This First Look shows how to manually code the REST interface, including developing a dispatch class. If you prefer to use the specification-first method, these dispatch classes are generated automatically and should not be edited. Advantages of using the specification-first definition include the ability to automatically generate documentation and client code from the specification, but you can use either way to define REST interfaces.
