Quick Start

from chzzk import ChzzkClient, FileTokenStorage

# Create client with OAuth support
client = ChzzkClient(
    client_id="your-client-id",
    client_secret="your-client-secret",
    redirect_uri="http://localhost:8080/callback",
    token_storage=FileTokenStorage("token.json"),
)

# Generate authorization URL
auth_url, state = client.get_authorization_url()
# User visits auth_url and authorizes the app

# Exchange code for token (after OAuth callback)
token = client.authenticate(code="auth-code", state=state)

# Use the API
user = client.user.get_me()
print(f"Channel: {user.channel_name}")

Features

Sync/Async Support

Both synchronous and asynchronous clients are available:

# Synchronous
from chzzk import ChzzkClient

with ChzzkClient(client_id="...", client_secret="...") as client:
    user = client.user.get_me()

# Asynchronous
from chzzk import AsyncChzzkClient

async with AsyncChzzkClient(client_id="...", client_secret="...") as client:
    user = await client.user.get_me()

Token Storage

Multiple token storage options:

from chzzk import InMemoryTokenStorage, FileTokenStorage, CallbackTokenStorage

# In-memory (default)
storage = InMemoryTokenStorage()

# File-based persistence
storage = FileTokenStorage("token.json")

# Custom callback
storage = CallbackTokenStorage(
    get_callback=lambda: load_from_db(),
    save_callback=lambda token: save_to_db(token),
    delete_callback=lambda: delete_from_db(),
)

Realtime Events

Receive chat, donation, and subscription events in realtime:

from chzzk import ChzzkClient, ChatEvent, DonationEvent, SubscriptionEvent

client = ChzzkClient(...)
event_client = client.create_event_client()

@event_client.on_chat
def on_chat(event: ChatEvent):
    print(f"{event.profile.nickname}: {event.content}")

@event_client.on_donation
def on_donation(event: DonationEvent):
    print(f"{event.donator_nickname} donated {event.pay_amount}won")

@event_client.on_subscription
def on_subscription(event: SubscriptionEvent):
    print(f"{event.subscriber_nickname} subscribed!")

# Connect and subscribe
event_client.connect()
event_client.subscribe_chat()
event_client.subscribe_donation()
event_client.subscribe_subscription()
event_client.run_forever()

Usage Examples

OAuth Authentication Flow

from chzzk import ChzzkClient, FileTokenStorage

client = ChzzkClient(
    client_id="your-client-id",
    client_secret="your-client-secret",
    redirect_uri="http://localhost:8080/callback",
    token_storage=FileTokenStorage("token.json"),
    auto_refresh=True,  # Automatically refresh expired tokens
)

# 1. Generate authorization URL
auth_url, state = client.get_authorization_url()
print(f"Visit: {auth_url}")

# 2. After user authorizes, exchange code for token
token = client.authenticate(code="received-code", state=state)

# 3. Refresh token manually if needed
new_token = client.refresh_token()

# 4. Revoke token on logout
client.revoke_token()

Channel & Live Information

# Get channel info
channel = client.channel.get_channel("channel-id")
print(f"Channel: {channel.channel_name}")
print(f"Description: {channel.channel_description}")

# Get followers
followers = client.channel.get_followers(size=20)
for follower in followers.data:
    print(f"Follower: {follower.nickname}")

# Get live broadcasts
lives = client.live.get_lives(size=10)
for live in lives.data:
    print(f"{live.channel_name}: {live.live_title} ({live.concurrent_user_count} viewers)")

# Get/Update live settings
setting = client.live.get_setting()
client.live.update_setting(default_live_title="My Stream Title")

Chat Messages

# Send chat message
client.chat.send_message(channel_id="channel-id", message="Hello!")

# Set chat announcement
client.chat.set_notice(
    channel_id="channel-id",
    message="Welcome to the stream!",
)

# Get/Update chat settings
settings = client.chat.get_settings(channel_id="channel-id")
client.chat.update_settings(
    channel_id="channel-id",
    chat_available_group="FOLLOWER",
)

Async Example

import asyncio
from chzzk import AsyncChzzkClient, FileTokenStorage

async def main():
    async with AsyncChzzkClient(
        client_id="your-client-id",
        client_secret="your-client-secret",
        redirect_uri="http://localhost:8080/callback",
        token_storage=FileTokenStorage("token.json"),
    ) as client:
        # Get user info
        user = await client.user.get_me()
        print(f"Channel: {user.channel_name}")

        # Get live broadcasts
        lives = await client.live.get_lives(size=10)
        for live in lives.data:
            print(f"{live.channel_name}: {live.live_title}")

asyncio.run(main())

    AuthenticationError,     # 401 errors
    InvalidTokenError,       # Invalid/expired token
    InvalidClientError,      # Invalid client credentials
    ForbiddenError,          # 403 errors

except InvalidTokenError:
    # Token is invalid or expired
    token = client.refresh_token()
except RateLimitError:
    # Rate limit exceeded, wait and retry
    time.sleep(60)
except ChzzkAPIError as e:

Unofficial API

In addition to the official API, we provide an unofficial API using Naver cookie authentication. This enables real-time chat receiving/sending functionality.

⚠️ The unofficial API may change at any time and is not officially supported.

Unofficial Chat Client

Synchronous version:

from chzzk.unofficial import UnofficialChatClient, ChatMessage

chat = UnofficialChatClient(
    nid_aut="your-nid-aut-cookie",
    nid_ses="your-nid-ses-cookie",
)

@chat.on_chat
def on_chat(msg: ChatMessage):
    print(f"{msg.nickname}: {msg.content}")

@chat.on_donation
def on_donation(msg):
    print(f"{msg.nickname} donated {msg.pay_amount}won")

chat.connect("channel-id")
chat.send_message("Hello!")
chat.run_forever()

Asynchronous version:

from chzzk.unofficial import AsyncUnofficialChatClient, ChatMessage

async with AsyncUnofficialChatClient(
    nid_aut="your-nid-aut-cookie",
    nid_ses="your-nid-ses-cookie",
) as chat:
    @chat.on_chat
    async def on_chat(msg: ChatMessage):
        print(f"{msg.nickname}: {msg.content}")

    await chat.connect("channel-id")
    await chat.send_message("Hello!")
    await chat.run_forever()

How to Get Naver Cookies

1. Log in to Naver
2. Browser Developer Tools (F12) → Application → Cookies
3. Copy NID_AUT and NID_SES cookie values

Unofficial API Exception Handling

from chzzk import ChatConnectionError, ChatNotLiveError

try:
    chat.connect("channel-id")
except ChatNotLiveError:
    print("Channel is not currently live")
except ChatConnectionError as e:
    print(f"Connection failed: {e}")

Command Line Interface

A CLI is available for quick access to the unofficial API features.
