How to get a webhook on everyone who actually enters the webinar?

I have a webinar that I conduct every two weeks and during these two weeks I get about 100 registrants.

Now, on the day of the workshop, before it starts - as soon as you click on the join link, you get a form that asks for the registrant’s details to see who really came.

I want to create a webhook that will send me to MAKE every time a customer does enter the workshop and that way I can be monitored who really came to the workshop and who didn’t.

I found an option to do it through an APP here in ZOOM, but I can’t figure out how to verify the webhook link.

I added a video that might help to understand my problem a little better:

Thank you!
