This is a full implementation of the Twitch Helix API, EventSub and Chat in python 3.7+.
Install using pip:
pip install twitchAPI
A full API documentation can be found on readthedocs.org.

Setting up an Instance of the Twitch API and get your User ID:
from twitchAPI.twitch import Twitch from twitchAPI.helper import first import asyncio async def twitch_example(): # initialize the twitch instance, this will by default also create a app authentication for you twitch = await Twitch('app_id', 'app_secret') # call the API for the data of your twitch user # this returns a async generator that can be used to iterate over all results # but we are just interested in the first result # using the first helper makes this easy. user = await first(twitch.get_users(logins='your_twitch_user')) # print the ID of your user or do whatever else you want with it print(user.id) # run this example asyncio.run(twitch_example())The Twitch API knows 2 different authentications. App and User Authentication. Which one you need (or if one at all) depends on what calls you want to use.
It's always good to get at least App authentication even for calls where you don't need it since the rate limits are way better for authenticated calls.
Please read the docs for more details and examples on how to set and use Authentication!
App authentication is super simple, just do the following:
from twitchAPI.twitch import Twitch twitch = await Twitch('my_app_id', 'my_app_secret')To get a user auth token, the user has to explicitly click "Authorize" on the twitch website. You can use various online services to generate a token or use my build in Authenticator. For my Authenticator you have to add the following URL as a "OAuth Redirect URL": http://localhost:17563 You can set that here in your twitch dev dashboard.
from twitchAPI.twitch import Twitch from twitchAPI.oauth import UserAuthenticator from twitchAPI.type import AuthScope twitch = await Twitch('my_app_id', 'my_app_secret') target_scope = [AuthScope.BITS_READ] auth = UserAuthenticator(twitch, target_scope, force_verify=False) # this will open your default browser and prompt you with the twitch verification website token, refresh_token = await auth.authenticate() # add User authentication await twitch.set_user_authentication(token, target_scope, refresh_token)You can reuse this token and use the refresh_token to renew it:
from twitchAPI.oauth import refresh_access_token new_token, new_refresh_token = await refresh_access_token('refresh_token', 'client_id', 'client_secret')Optionally you can set a callback for both user access token refresh and app access token refresh.
from twitchAPI.twitch import Twitch async def user_refresh(token: str, refresh_token: str): print(f'my new user token is: {token}') async def app_refresh(token: str): print(f'my new app token is: {token}') twitch = await Twitch('my_app_id', 'my_app_secret') twitch.app_auth_refresh_callback = app_refresh twitch.user_auth_refresh_callback = user_refreshEventSub lets you listen for events that happen on Twitch.
The EventSub client runs in its own thread, calling the given callback function whenever an event happens.
There are multiple EventSub transports available, used for different use cases.
See here for more info about EventSub in general and the different Transports, including code examples: on readthedocs
A simple twitch chat bot. Chat bots can join channels, listen to chat and reply to messages, commands, subscriptions and many more.
