Hello,  
I am facing an issue in validating the webhook endpoint in zoom webhook app.  
So i’ve created a Webhook only app and i deployed a cloud function on GCP that executes agent status change upon receiving webhook notifications from zoom.  
The trigger url of the cloud function is  
https://\<\<region-project\_id\>\>.cloudfunctions.net/Agent\_Status

when i use this url in the “Event notification endpoint URL field” and try to validate i get the error “URL validation failed. Try again later.”

can you please assist with this issue?

Regards,  
Ahmed
