Hi PagerDuty Community,

I'm currently working on integrating ServiceNow with PagerDuty using the REST API. While testing the incident update (status change to "acknowledged") via Postman, I'm encountering the following error response:

My API details and headers are correct. I used the same call from the PagerDuty REST Explorer; there, the integration is working fine.

{ "error": { "errors": [ "Incident error illegitimate_requester_error" ], "code": 2001, "message": "Invalid Input Provided" } }
