Upon further testing I am not seeing the callback verification request.
My call back url is https://website:8057/twitch/eventsub/callback
I am watching for any post request on that port and am not seeing anything come in. I have verified the url by sending a generic post message to the callback URL and I do see that come in, just nothing from twitch. What am I missing, is specifying the port causing an issue (I hope this isn’t the case)?
