REST Server IO
APEX can act as REST requestor on the input as well as on
the output interface. The media type is
``application/json``, so this plugin only works with
- the JSON Event protocol.
+ the JSON Event protocol. This plugin allows APEX to send REST requests
+ and to receive the reply of that request without tying up APEX resources
+ while the request is being processed. The REST Requestor pairs a REST
+ requestor producer and consumer together to handle the REST request
+ and response. The REST request is created from an APEX output event
+ and the REST response is input into APEX as a new input event.
