+== REST Requestor 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 does only work with the JSON Event protocol.
+
+=== REST Requestor Input
+
+APEX will connect to a given URL to request an input.

+"carrierTechnologyParameters": {
+  "carrierTechnology": "RESTREQUESTOR", <1>
+  "parameterClassName": "org.onap.policy.apex.plugins.event.carrier.restrequestor.RESTRequestorCarrierTechnologyParameters",

+
+<1> set REST requestor as carrier technology
+<2> the URL of the HTTP server for events
+<3> use HTTP PUT (remove this line to use HTTP POST)
+<4> request timeout in milliseconds
+
+Further settings are required on the consumer to define the event that is requested, for example:
+
+[source%nowrap,json]

+"eventNameFilter": "GuardResponseEvent", <2>
+"requestorMode": true, <3>
+"requestorPeer": "GuardRequestorProducer", <4>
+"requestorTimeout": 500 <5>
+----
+
+<1> the event name
+<2> a filter on the event
+<3> the mode of the requestor
+<4> a peer for the requestor
+<5> a general request timeout
+
+
+=== REST Requestor Output
+
+APEX will connect to a given URL to send events, but not receive any events.
