Webhook payloads: triggerUuid vs orginalTriggerUuid

Platform discussions monday dev

Hello,

I am looking at a payload example for a create_item event:

"event": {
  "userId": 9603417,
  "originalTriggerUuid": null,
  "boardId": 1771812698,
  "pulseId": 1772099344,
  "pulseName": "Create_item webhook",
  "groupId": "topics",
  "groupName": "Group Title",
  "groupColor": "#579bfc",
  "isTopGroup": true,
  "columnValues": {},
  "app": "monday",
  "type": "create_pulse",
  "triggerTime": "2021-10-11T09:07:28.210Z",
  "subscriptionId": 73759690,
  "triggerUuid": "b5ed2e17c530f43668de130142445cba"
 }

What is the difference between triggerUuid vs orginalTriggerUuid and in what case is the latter filled? Does it have to do with retries?

Thank you
