Multiple user_ids in streams endpoint

The correct URL construction is

https://api.twitch.tv/helix/streams?user_id=26610234&user_id=567803342

You might have to use not params and string concantenate the URL instead

payload = {‘user_id’:‘user1’,‘user_id’:‘user2’…}

Creates and object of only on entry

payload = {‘user_id’:[‘user1’,‘user2']}

Make work but I’d not to familair with Python.

So building the URL manually instead of using params might be the way to go
