Somehow i cant confirm Subscriptions for webhooks

API
2

  1. Consider moving from request, request is deprecated

  2. You mis spelled challenge in your req.query call to res.send

Should be

res.send(req.query['hub.challenge'])

https://github.com/BarryCarlyon/twitch_misc/blob/master/webhooks/handlers/nodejs/receive.js#L63

You can just do

res.send(req.query['hub.challenge']);

No need to faff with headers

  1. You won’t get any posts until you confirm the subscriptions

  2. Did your code log the incoming get request and/or did ngrok log it? It’s possible that you hit the ngrok limits. So ngrok is ok for spot tests but best avoided after that
