Monday Webook doesn't trigger Request Received in Power Automate

Hi everyone,

I’m trying to connect a Monday board to Power Automate using a webhook, but my flow never gets triggered. I always get this error:

The provided URL has not returned the requested challenge.

I know that I have to use response with challenge as body, but the flow doesn’t even got trigger.

Has anyone encountered this issue or found a workaround?

Thanks in advance!
