Hello community,
I need to set up an integration within Opsgenie and Betterstack. In particular, I have to create an automation that create automatically an Incident in Betterstack when a manual Incident is created using Opsgenie.
I can use custom code that will call Betterstack APIs to create incident but I can't find a way to trigger this code from Opsgenie (I've found webhook integration bit didn't find how to set up the URL).
I also tried Zapier but didn't find a way to put Opsgenie as the starting trigger as you can see in the attached screenshot.

I can't find documentation useful.
Could you help me please?
