Yes, I have setup the GET request but when I try to subscribe nothing is sent from Twitch.
Here is my CURL request.
curl -H ‘Client-ID: {CLIENT_ID}’
-H ‘Content-Type: application/json’
-X POST -d ‘{“hub.mode”:“subscribe”,
“hub.topic”:“https://api.twitch.tv/helix/users/follows?first=1&to_id=***”,
“hub.callback”:"***",
“hub.lease_seconds”:“0”,
“hub.secret”: “s3cRe7”}’
