kinde-python-sdk 2.2.0

Connect your app to the Kinde platform

Kinde Python SDK

The Kinde SDK for Python.

You can also use the Python starter kit here.

🚨 Important: Migrating from v1?

If you're upgrading from Kinde Python SDK v1, the API has changed significantly. The KindeClient class has been completely replaced with OAuth.

📖 Migration Guide - Complete step-by-step migration instructions
📋 Quick Reference - At-a-glance v1 to v2 conversion table

Key Changes:

• KindeClient → OAuth (main authentication class)
• client.get_flag() → await feature_flags.get_flag() (feature flags)
• client.get_permission() → await permissions.get_permission() (permissions)
• Most operations are now asynchronous

Documentation

For details on integrating this SDK into your project, head over to the Kinde docs and see the Python SDK doc 👍🏼.

Basic Usage: Framework Integrations

The Kinde Python SDK provides seamless integration with popular Python web frameworks. Below are detailed guides for using Kinde with FastAPI and Flask.

FastAPI Integration

The kinde_fastapi module provides easy integration with FastAPI applications.

Installation

pip install fastapi uvicorn python-multipart

Basic Setup

from fastapi import FastAPI
from kinde_sdk.auth.oauth import OAuth

# Initialize FastAPI app
app = FastAPI()

# Initialize Kinde OAuth with FastAPI framework
kinde_oauth = OAuth(
    framework="fastapi",
    app=app
)

# Example home route
@app.get("/")
async def home(request: Request):
    if kinde_oauth.is_authenticated():
        user = kinde_oauth.get_user_info()
        return f"Welcome, {user.get('email', 'User')}!"
    return "Please log in"

Configuration

Create a .env file with your Kinde credentials:

KINDE_CLIENT_ID=your_client_id
KINDE_CLIENT_SECRET=your_client_secret
KINDE_REDIRECT_URI=http://localhost:8000/callback
KINDE_DOMAIN=your_kinde_domain

Available Routes

The FastAPI integration automatically provides these routes:

• /login - Redirects to Kinde login
• /callback - Handles OAuth callback
• /logout - Logs out the user
• /register - Redirects to Kinde registration
• /user - Returns user information

Protected Routes

from fastapi import Depends
from kinde_sdk.management.kinde_api_client import KindeApiClient

@router.get("/protected")
async def protected_route(
    kinde_client: KindeApiClient = Depends(get_kinde_client)
):
    return {"message": "This is a protected route"}

Flask Integration

The kinde_flask module provides easy integration with Flask applications.

Installation

pip install flask python-dotenv flask-session

Basic Setup

from flask import Flask
from kinde_sdk.auth.oauth import OAuth

# Initialize Flask app
app = Flask(__name__)

# Configure Flask session
app.config['SECRET_KEY'] = 'your-secret-key'
app.config['SESSION_TYPE'] = 'filesystem'
app.config['SESSION_PERMANENT'] = False

# Initialize Kinde OAuth with Flask framework
kinde_oauth = OAuth(
    framework="flask",
    app=app
)

# Example home route
@app.route('/')
def home():
    if kinde_oauth.is_authenticated():
        user = kinde_oauth.get_user_info()
        return f"Welcome, {user.get('email', 'User')}!"
    return "Please log in"

Configuration

Create a .env file with your Kinde credentials:

KINDE_CLIENT_ID=your_client_id
KINDE_CLIENT_SECRET=your_client_secret
KINDE_REDIRECT_URI=http://localhost:5000/callback
KINDE_DOMAIN=your_kinde_domain

Available Routes

The Flask integration automatically provides these routes:

• /login - Redirects to Kinde login
• /callback - Handles OAuth callback
• /logout - Logs out the user
• /register - Redirects to Kinde registration
• /user - Returns user information

Protected Routes

from functools import wraps
from flask import session, redirect

def login_required(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        if not kinde_oauth.is_authenticated():
            return redirect('/login')
        return f(*args, **kwargs)
    return decorated_function

@app.route('/protected')
@login_required
def protected_route():
    return {"message": "This is a protected route"}

Security Considerations

For both FastAPI and Flask integrations:

1. Always use HTTPS in production
2. Use a secure session secret key
3. Implement proper state parameter validation
4. Handle OAuth errors appropriately
5. Implement proper session management
6. Consider implementing CSRF protection

After initializing both OAuth and KindeApiClient use the following fn to get proper urls: api_client.fetch_openid_configuration(oauth)

Kinde Management API Module

This module provides a client for the Kinde Management API, allowing you to manage users, organizations, roles, permissions, and feature flags programmatically.

Note for v1 users: The Management API usage has changed in v2. See the Migration Guide for details on the new ManagementClient class.

Installation

No additional installation is required if you already have the Kinde Python SDK installed. The Management API module is included as part of the SDK.

Usage

The Management API client requires:

• Your Kinde domain
• Client ID
• Client secret

Initializing the client

You can access the Management API through the existing KindeApiClient:

from kinde_sdk.management.kinde_api_client import KindeApiClient
from kinde_sdk.enums import GrantType

# Initialize the client with client credentials
client = KindeApiClient(
    domain="your-domain.kinde.com",
    callback_url="https://your-app.com/callback",
    client_id="your-client-id",
    client_secret="your-client-secret", # Required for management API
    grant_type=GrantType.CLIENT_CREDENTIALS,
)

# Get the management client
management = client.get_management()

Managing Users

# List users
users = management.get_users(page_size=10)

# Get a specific user
user = management.get_user(user_id="user_id")

# Create a new user
new_user = management.create_user(
    first_name="John",
    last_name="Doe",
    email="[e-mail]"
)

# Update a user
updated_user = management.update_user(
    user_id="user_id",
    first_name="John",
    last_name="Smith"
)

# Delete a user
result = management.delete_user(user_id="user_id")

Managing Organizations

# List organizations
organizations = management.get_organizations(page_size=10)

# Get a specific organization
org = management.get_organization(org_code="org_code")

# Create a new organization
new_org = management.create_organization(
    name="Example Organization"
)

# Update an organization
updated_org = management.update_organization(
    org_code="org_code",
    name="Updated Organization Name"
)

# Delete an organization
result = management.delete_organization(org_code="org_code")

Managing Roles

# List roles
roles = management.get_roles(page_size=10)

# Get a specific role
role = management.get_role(role_id="role_id")

# Create a new role
new_role = management.create_role(
    name="Admin",
    description="Administrator role",
    key="admin_role"
)

# Update a role
updated_role = management.update_role(
    role_id="role_id",
    name="Super Admin",
    description="Super administrator role"
)

# Delete a role
result = management.delete_role(role_id="role_id")

Managing Feature Flags

# List feature flags
flags = management.get_feature_flags(page_size=10)

# Create a new feature flag
new_flag = management.create_feature_flag(
    name="Dark Mode",
    key="dark_mode",
    description="Enable dark mode theme",
    type="boolean",
    default_value=False
)

# Update a feature flag
updated_flag = management.update_feature_flag(
    feature_flag_id="flag_id",
    name="Dark Theme",
    description="Enable dark theme for the application"
)

# Delete a feature flag
result = management.delete_feature_flag(feature_flag_id="flag_id")

Token Management

The Management API client automatically handles token management using client credentials:

• Tokens are automatically obtained when needed
• Tokens are cached to avoid unnecessary requests
• Tokens are refreshed when they expire
• Multiple instances of the client with the same domain and client ID share the same token

Error Handling

All API methods can raise exceptions for HTTP errors. It's recommended to wrap calls in try/except blocks:

try:
    user = management.get_user(user_id="non_existent_id")
except Exception as e:
    print(f"Error: {e}")

Complete example given below

from kinde_sdk.management.kinde_api_client import KindeApiClient
from kinde_sdk.enums import GrantType

def main():
    """Main function demonstrating Management API usage."""
    # Initialize the Kinde client with management capabilities
    client = KindeApiClient(

        callback_url="https://your-app.com/callback",  # Your auth callback URL
        client_id="your-client-id",  # Your client ID
        client_secret="your-client-secret",  # Required for management API
        grant_type=GrantType.CLIENT_CREDENTIALS,  # Use client credentials for management API
    )

    # Get the management client
    management = client.get_management()
    
    # Example 1: List users
    print("Example 1: List users")

Advanced Usage: Direct Storage Management

This section covers direct interaction with the StorageManager for custom storage solutions. This is considered an advanced approach. For most use cases, the framework integrations provide sufficient storage handling.

Note for v1 users: Storage management has been completely redesigned in v2. See the Migration Guide for details on the new storage abstraction layer.

Direct StorageManager Usage

from kinde_sdk.auth import OAuth
from kinde_sdk.core.storage import StorageManager

# Basic initialization via OAuth
# This is the recommended way to initialize the storage system
# OAuth automatically initializes the StorageManager with the provided config
oauth = OAuth(
    client_id="your_client_id",
    client_secret="your_client_secret",
    redirect_uri="your_redirect_uri"
)

# Direct access to the storage manager
# This is safe to use after OAuth initialization
storage_manager = StorageManager()

# Store authentication data
storage_manager.set("user_tokens", {
    "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
    "refresh_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
    "expires_at": 1678901234
})

# Retrieve tokens
tokens = storage_manager.get("user_tokens")
if tokens:
    access_token = tokens.get("access_token")
    # Use the access token for API requests
    
# Delete tokens when logging out
storage_manager.delete("user_tokens")

Using a Custom Storage Backend

oauth = OAuth(
    client_id="your_client_id",
    storage_config={
        "type": "local_storage",
        "options": {
            # backend-specific options
        }
    }
)

Handling Multi-Device Usage

The StorageManager automatically assigns a unique device ID to each client instance, ensuring that the same user logged in on different devices won't experience session clashes. Keys are namespaced with the device ID by default.

# Get the current device ID
device_id = storage_manager.get_device_id()
print(f"Current device ID: {device_id}")

# Clear all data for the current device (useful for logout)
storage_manager.clear_device_data()

# For data that should be shared across all devices for the same user
# Use the "user:" prefix
storage_manager.set("user:shared_preferences", {"theme": "dark"})

# For data that should be global across all users and devices
# Use the "global:" prefix
storage_manager.set("global:app_settings", {"version": "1.0.0"})

Best Practices for Storage Management

1. Always initialize OAuth first: The OAuth constructor initializes the StorageManager, so create your OAuth instance before accessing the storage.

2. Manual initialization (if needed): If you need to use StorageManager before creating an OAuth instance, explicitly initialize it first:

# Manual initialization
storage_manager = StorageManager()
storage_manager.initialize({"type": "memory"})  # or your preferred storage config

# You can also provide a specific device ID
storage_manager.initialize(
    config={"type": "memory"},
    device_id="custom-device-identifier"
)

# Now safe to use
storage_manager.set("some_key", {"some": "value"})

3. Safe access pattern: If you're unsure about initialization status, you can use this pattern:

storage_manager = StorageManager()
if not storage_manager._initialized:
    storage_manager.initialize()
    
# Now safe to use
data = storage_manager.get("some_key")

4. Single configuration: Configure the storage only once at application startup. Changing storage configuration mid-operation may lead to data inconsistency.

5. Access from anywhere: After initialization, you can safely access the StorageManager from any part of your application without passing it around.

6. Device-specific data: Understand that by default, data is stored with device-specific namespacing. To share data across devices, use the appropriate prefixes.

7. Complete logout: To ensure all device-specific data is cleared during logout, call storage_manager.clear_device_data().

Version Tracking And Framework detection

The implementation generates headers in the exact format specified:

No Framework: Python/2.0.0

With Framework: Python-Flask/2.0.0/3.11.0/python

Framework Detection

Auto-detects these frameworks:

Django, Flask, FastAPI (more frameworks can be added)

Version Detection

SDK Version: Automatically detected from package metadata Python Version: Detected from sys.version_info
Fallback: Uses "2.0.0-dev" during development
