Zoom Webhook only App verification token error

I have integrated Meeting Web SDK in our project. I have subscribed for the end meeting event from the Event-only app. Now when I got the response from zoom at the time of end meeting. I got 2-3 tokens in authorization with the body. So how can I authenticate it’s from zoom or not? (P.S. I got only 1 verification token from Zoom Event-only App.)

What can I do now in this scenario?
