Consuming RESTful WS with RAML Definition in Anypoint Studio

1. MULE ESB – CONSUMING
RESTFUL WEB SERVICES
WITH RAML DEFINITION
Quick guide to call RESTful WS defined by RAML

2. Using RAML Definition to configure HTTP Request - 1
RAML Definition of a Web Service make the build of Request in Anypoint easier and quicker.
In this example we will start from a new flow, with a simple HTTP Listener as shown:
HTTP Listener Configuration can listen classically on localhost at port 8081, in example.

3. Using RAML Definition to configure HTTP Request - 2
To consume RESTful WS we add an HTTP Request after our listener:
In Mule Properties Tab of HTTP Request we will create a new Connector, clicking on ‘+’ button

4. Using RAML Definition to configure HTTP Request - 3
In Connector Configuration, in the section of API Configuration, it is needed to indicate RAML file that defines
your WS:
Automatically, in host, port and base path fields, values defined in RAML for the properties of RESTful WS will be
imported.

5. Using RAML Definition to configure HTTP Request - 4
In our HTTP Request, after importing RAML, we will be able, in URL settings, to call the paths defined and the
allowed methods in RAML file (RAML example taken by mulesoft.com):
Automatically, also URI Params and Query params with their default values defined in RAML will be
configured in HTTP Request.
