User Authorization to validate/confirm twitch username

API
3

Thanks for the reply, Dist!

when trying to curl that endpoint with the response token I’m getting :
{
“error”: “Bad Request”,
“status”: 400,
“message”: “Must provide an ID, Login or OAuth Token.”
}

I used the endpoint: https://api.twitch.tv/helix/users

my Headers:
Client-ID: <CLIENT ID>,
Authorization: Bearer <INITIAL RESPONSE TOKEN>
