Thx for your reply.
How i couldn’t see it…
With a GET request, now the helix api return an “Unauthorized” error.
Even if i refresh my token with the “channel:read:subscriptions” scope, still the same error.
This is my very first time with twitch api, so i don’t understand yet all the subtleties.
I hope not making a mistake with the “broadcaster_id” parameter, witch for me is my channel name (lowercase).
