Usage#
These are some basic usage examples, please visit the dedicated pages for more info.
TwitchAPI#
Calls to the Twitch Helix API, this is the base of this library.
See here for more info: twitchAPI.twitch
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())
Authentication#
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.
See here for more info about user authentication: twitchAPI.oauth
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
EventSub#
EventSub lets you listen for events that happen on Twitch.
See here for more info: twitchAPI.eventsub
from twitchAPI.twitch import Twitch
from twitchAPI.helper import first
from twitchAPI.eventsub import EventSub
from twitchAPI.oauth import UserAuthenticator
from twitchAPI.types import AuthScope
import asyncio
TARGET_USERNAME = 'target_username_here'
EVENTSUB_URL = 'https://url.to.your.webhook.com'
APP_ID = 'your_app_id'
APP_SECRET = 'your_app_secret'
TARGET_SCOPES = [AuthScope.MODERATOR_READ_FOLLOWERS]
async def on_follow(data: dict):
# our event happend, lets do things with the data we got!
print(data)
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))
# the user has to authenticate once using the bot with our intended scope.
# since we do not need the resulting token after this authentication, we just discard the result we get from authenticate()
# Please read up the UserAuthenticator documentation to get a full view of how this process works
auth = UserAuthenticator(twitch, TARGET_SCOPES)
await auth.authenticate()
# 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
event_sub.start()
# subscribing to the desired eventsub hook for our user
# the given function (in this example on_follow) will be called every time this event is triggered
# the broadcaster is a moderator in their own channel by default so specifying both as the same works in this example
await event_sub.listen_channel_follow_v2(user.id, user.id, on_follow)
# eventsub will run in its own process
# so lets just wait for user input before shutting it all down again
try:
input('press Enter to shut down...')
finally:
# stopping both eventsub as well as gracefully closing the connection to the API
await event_sub.stop()
await twitch.close()
print('done')
# lets run our example
asyncio.run(eventsub_example())
PubSub#
PubSub enables you to subscribe to a topic, for updates (e.g., when a user cheers in a channel).
See here for more info: twitchAPI.pubsub
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'
USER_SCOPE = [AuthScope.WHISPERS_READ]
TARGET_CHANNEL = 'teekeks42'
async def callback_whisper(uuid: UUID, data: dict) -> None:
print('got callback for UUID ' + str(uuid))
pprint(data)
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)
pubsub.start()
# you can either start listening before or after you started pubsub.
uuid = await pubsub.listen_whispers(user.id, 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)
pubsub.stop()
await twitch.close()
asyncio.run(run_example())
Chat#
A simple twitch chat bot. Chat bots can join channels, listen to chat and reply to messages, commands, subscriptions and many more.
See here for more info: twitchAPI.chat
from twitchAPI import Twitch
from twitchAPI.oauth import UserAuthenticator
from twitchAPI.types import AuthScope, ChatEvent
from twitchAPI.chat import Chat, EventData, ChatMessage, ChatSub, ChatCommand
import asyncio
APP_ID = 'my_app_id'
APP_SECRET = 'my_app_secret'
USER_SCOPE = [AuthScope.CHAT_READ, AuthScope.CHAT_EDIT]
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
await ready_event.chat.join_room(TARGET_CHANNEL)
# 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 {msg.room.name}, {msg.user.name} said: {msg.text}')
# this will be called whenever someone subscribes to a channel
async def on_sub(sub: ChatSub):
print(f'New subscription in {sub.room.name}:\\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')
else:
await cmd.reply(f'{cmd.user.name}: {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!
chat.start()
# lets run till we press enter in the console
try:
input('press ENTER to stop\\n')
finally:
# now we can close the chat bot and the twitch api client
chat.stop()
await twitch.close()
# lets run our setup
asyncio.run(run())
