GoAlert as Custom Webhook Destination

Hi there,

I created a webhook destination for GoAlert. I have configured a trigger message as given below since gaolert accepts summary & details as params.

But, when the alert is triggered I only get the notifications but alert summary & details are missing.

Opensearch version: 2.1.0

curl -XPOST https://<example.goalert.me>/api/v2/generic/incoming?token=key-here&summary=test&details=test

I am not sure what am missing here. Appreciate your help.

Best regards
