Helix Get follower user name from user ID number

Yes, like I just said, send the request with the id parameter and you’ll get a response along the lines of:

{
  "data": [{
    "id": "44322889",
    "login": "dallas",
    "display_name": "dallas",
    "type": "staff",
    "broadcaster_type": "",
    "description": "Just a gamer playing games and chatting. :)",
    "profile_image_url": "https://static-cdn.jtvnw.net/jtv_user_pictures/dallas-profile_image-1a2c906ee2c35f12-300x300.png",
    "offline_image_url": "https://static-cdn.jtvnw.net/jtv_user_pictures/dallas-channel_offline_image-1a2c906ee2c35f12-1920x1080.png",
    "view_count": 191836881,
    "email": "login@provider.com"
  }]
}

Login is their username.
