Basic API calls

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

# run this 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

App authentication is super simple, just do the following:

from twitchAPI.twitch import Twitch
twitch = await Twitch('my_app_id', 'my_app_secret')

User Authentication

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.types 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')

AuthToken refresh callback

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_refresh


PubSub enables you to subscribe to a topic, for updates (e.g., when a user cheers in a channel).

A more detailed documentation can be found here on readthedocs

from twitchAPI.pubsub import PubSub
from twitchAPI.twitch import Twitch
from twitchAPI.helper import first
from twitchAPI.types import AuthScope
from twitchAPI.oauth import UserAuthenticator
import asyncio
from pprint import pprint
from uuid import UUID

APP_ID = 'my_app_id'
APP_SECRET = 'my_app_secret'
TARGET_CHANNEL = 'teekeks42'

async def callback_whisper(uuid: UUID, data: dict) -> None:
    print('got callback for UUID ' + str(uuid))

async def run_example():
    # setting up Authentication and getting your user id
    twitch = await Twitch(APP_ID, APP_SECRET)
    auth = UserAuthenticator(twitch, [AuthScope.WHISPERS_READ], force_verify=False)
    token, refresh_token = await auth.authenticate()
    # you can get your user auth token and user auth refresh token following the example in twitchAPI.oauth
    await twitch.set_user_authentication(token, [AuthScope.WHISPERS_READ], refresh_token)
    user = await first(twitch.get_users(logins=[TARGET_CHANNEL]))

    # starting up PubSub
    pubsub = PubSub(twitch)
    # you can either start listening before or after you started pubsub.
    uuid = await pubsub.listen_whispers(, callback_whisper)
    input('press ENTER to close...')
    # you do not need to unlisten to topics before stopping but you can listen and unlisten at any moment you want
    await pubsub.unlisten(uuid)
    await twitch.close()


EventSub 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.

A more detailed documentation, including the setup requirements can be found here on readthedocs

Short code example:

from twitchAPI.twitch import Twitch
from twitchAPI.helper import first
from twitchAPI.eventsub import EventSub
import asyncio

TARGET_USERNAME = 'target_username_here'
APP_ID = 'your_app_id'
APP_SECRET = 'your_app_secret'

async def on_follow(data: dict):
    # our event happend, lets do things with the data we got!

async def eventsub_example():
    # create the api instance and get the ID of the target user
    twitch = await Twitch(APP_ID, APP_SECRET)
    user = await first(twitch.get_users(logins=TARGET_USERNAME))

    # basic setup, will run on port 8080 and a reverse proxy takes care of the https and certificate
    event_sub = EventSub(EVENTSUB_URL, APP_ID, 8080, twitch)
    # unsubscribe from all old events that might still be there
    # this will ensure we have a clean slate
    await event_sub.unsubscribe_all()
    # start the eventsub client
    # subscribing to the desired eventsub hook for our user
    # the given function will be called every time this event is triggered
    await event_sub.listen_channel_follow(, on_follow)

    # eventsub will run in its own process
    # so lets just wait for user input before shutting it all down again
        input('press Enter to shut down...')
        # stopping both eventsub as well as gracefully closing the connection to the API
        await event_sub.stop()
        await twitch.close()

# lets run our example


A simple twitch chat bot. Chat bots can join channels, listen to chat and reply to messages, commands, subscriptions and many more.

A more detailed documentation can be found here on readthedocs

Example code for a simple bot

from twitchAPI import Twitch
from twitchAPI.oauth import UserAuthenticator
from twitchAPI.types import AuthScope, ChatEvent
from import Chat, EventData, ChatMessage, ChatSub, ChatCommand
import asyncio

APP_ID = 'my_app_id'
APP_SECRET = 'my_app_secret'
TARGET_CHANNEL = 'teekeks42'

# this will be called when the event READY is triggered, which will be on bot start
async def on_ready(ready_event: EventData):
    print('Bot is ready for work, joining channels')
    # join our target channel, if you want to join multiple, either call join for each individually
    # or even better pass a list of channels as the argument
    # you can do other bot initialization things in here

# this will be called whenever a message in a channel was send by either the bot OR another user
async def on_message(msg: ChatMessage):
    print(f'in {}, {} said: {msg.text}')

# this will be called whenever someone subscribes to a channel
async def on_sub(sub: ChatSub):
    print(f'New subscription in {}:\\n'
          f'  Type: {sub.sub_plan}\\n'
          f'  Message: {sub.sub_message}')

# this will be called whenever the !reply command is issued
async def test_command(cmd: ChatCommand):
    if len(cmd.parameter) == 0:
        await cmd.reply('you did not tell me what to reply with')
        await cmd.reply(f'{}: {cmd.parameter}')

# this is where we set up the bot
async def run():
    # set up twitch api instance and add user authentication with some scopes
    twitch = await Twitch(APP_ID, APP_SECRET)
    auth = UserAuthenticator(twitch, USER_SCOPE)
    token, refresh_token = await auth.authenticate()
    await twitch.set_user_authentication(token, USER_SCOPE, refresh_token)

    # create chat instance
    chat = await Chat(twitch)

    # register the handlers for the events you want

    # listen to when the bot is done starting up and ready to join channels
    chat.register_event(ChatEvent.READY, on_ready)
    # listen to chat messages
    chat.register_event(ChatEvent.MESSAGE, on_message)
    # listen to channel subscriptions
    chat.register_event(ChatEvent.SUB, on_sub)
    # there are more events, you can view them all in this documentation

    # you can directly register commands and their handlers, this will register the !reply command
    chat.register_command('reply', test_command)

    # we are done with our setup, lets start this bot up!

    # lets run till we press enter in the console
        input('press ENTER to stop\n')
        # now we can close the chat bot and the twitch api client
        await twitch.close()

# lets run our setup
