Hi everyone,

I'm currently building a workflow with an incoming webhook trigger and I'm facing a problem that I'm stuck with, maybe someone of you has already had that.

The trigger itself works flawlessly: Requests arrive, the webhook responds with HTTP 200, I've tested this several times directly via the browser (both with content type text/plain and application/json, both without difference). The problem is the assignment reference (i.e. the field mapping for the trigger): There, despite multiple incoming test requests, simply no sample data set is displayed. Even the “Check if there are new requests” button does not make any changes, no matter how often I click on it.

Without this assignment reference, however, the trigger cannot be saved at all; GHL shows the message “An assignment reference is required for an incoming webhook trigger.”

What I've ruled out so far:

The webhook URL is correctly stored and accessible. The content type of the request makes no difference. The problem occurs regardless of which source the test request comes from.

My guess is that the assignment reference only accepts an example request if the trigger step in the workflow editor is active in the “Waiting for test data” state at the exact moment when the request arrives, and each request before or after that is acknowledged with 200 but is not adopted as an example. Can anyone confirm this or does another approach to reliably get the assignment reference filled?

Thank you guys in advance!
