+callbackUri of the "Create a PM job (v2)" API.
+
+Response Codes
+--------------
+
+Tacker expects a "204 No Content" response from the endpoint of the API consumer.
+If any other response code is returned, it will be treated as an error.

+ThresholdCrossedNotification
+============================
+
+.. rest_method::  POST < callbackUri (provided by API consumer) >
+
+The POST method delivers a notification about threshold crossing from Tacker
+to the API consumer.

+by VNF performance management threshold, Tacker sends this notification to the
+endpoint configured in the callbackUri of the "Create a PM threshold (v2)" API.
+
+Response Codes
+--------------
+
+Tacker expects a "204 No Content" response from the endpoint of the API consumer.

+Test the notification endpoint (VNF PM)
+=======================================
+
+.. rest_method::  GET < callbackUri (provided by API consumer) >
+
+The GET method test the notification endpoint.
+
+When a PM job is created using the "Create a PM job (v2)" API or a PM threshold
+is created using the "Create a PM threshold (v2)" API,
+Tacker sends this notification to the endpoint configured with callbackUri to
+confirm communication.
+
