Event Name
ProcedureStateChanged
Event Description
If you have configured event notifications for your application, after the status of a task flow is changed, your application backend will be notified either by a “normal callback” or a “reliable callback”. For the content of the callback, see ProcedureTask.
Example
Normal callback
In the normal callback mode, your callback URL will receive an HTTP POST request from VOD. The content of the callback is included in the request body, as shown below (fields with null values are omitted):
{
    "EventType":"ProcedureStateChanged",
    "ProcedureStateChangeEvent":{
