Custom Connectors Webhook Trigger Error



I have created a custom connector set with 60+ actions successfully, but I cannot figure out how to configure Webhook triggers for the connectors. I have included a link below to the Bluebeam API documentation that should have everything needed to  successfully create a Webhook trigger but it will not work for me.


can someone please show me how the subscribe request, the callback ur, and response are supposed to be setup and how an unsubscribe function is incorporated?


I keep receiving the following error message:



"$id": "1",

"Message": "The request is invalid.",

"ModelState": {

"$id": "2",

"value": [

"The request body can't be null or empty"



"ErrorCode": 99996



Here is the sample Bluebeam API Documentation for event subscription and notifications:



Here is how I currently have my webhook trigger setup:

And this is how I have the body of the request formatted.

Thank you but I have reviewed that documentation multiple times and still no matter how I configure the trigger it keeps giving me that error message.

If you could look at the Bluebeam API sample requests and responses I provided and see if I have Incorrectly entered the parameters into the Custom Connector Trigger UI it would be greatly appreciated.

I solved this myself. It was an issue with a HostUrl Policy that kept messing with the request.
