Check if Users Follow a Playlist

check_users_following(
  playlist_id,
  ids,
  authorization = get_spotify_authorization_code()
)

`playlist_id`	Required. The Spotify ID of the playlist.
`ids`	Required. Spotify User IDs; the ids of the users that you want to check to see if they follow the playlist. Maximum: 5 ids.
`authorization`	Required. A valid access token from the Spotify Accounts service. See the Web API authorization Guide for more details. Following a playlist can be done publicly or privately. Checking if a user publicly follows a playlist doesn’t require any scopes; if the user is publicly following the playlist, this endpoint returns `TRUE`. Checking if the user is privately following a playlist is only possible for the current user when that user has granted access to the `playlist-read-private` scope. See Using Scopes.
