Problem with new EventSub

[Dist]

I am getting a Unauthorized 401 Must provide valid app token. This is the same way I am sending my app token for numerous other requests, is something different for EventSubs?

Are you sure you’re using the client_credentials auth flow to create an App token? Using a User token will not work.

Also when twitch sends the initial Get response of webhook_callback_verification_pending, am I supposed to verify the Header and send a 200 status (if it matches)? I don’t need to send back a challenge or anything like that (as needed for the existing webhooks). The second response (with the actual requested information) just needs a simple 200 status response correct?

EventSub uses a POST request for verification, not GET. Also you do need to send back a challenge, as shown in steps 3. 4, and 5 of the EventSub guide EventSub | Twitch Developers
