I was able to get an event following the above instructions in conjunction with verifying the webhook from the instructions harshil1712 had here, after modifying the Webhook from GET to POST. I appreciate the help, thank you.
Hope the OAuth issue isn’t too difficult of a fix as it seems that if I want certain other info like the title/game the moment a user goes live, I’ll have to make an HTTP request and the token will expire at some point again.
