Getting Started

1. Install the SDK

pip install auth0-server-python

If you’re using Poetry:

poetry install auth0-server-python

2. Create the Auth0 SDK client

Create an instance of the Auth0 client. This instance will be imported and used in anywhere we need access to the authentication methods.

from auth0_server_python.auth_server.server_client import ServerClient

auth0 = ServerClient(
    domain='<AUTH0_DOMAIN>',
    client_id='<AUTH0_CLIENT_ID>',
    client_secret='<AUTH0_CLIENT_SECRET>',
    secret='<AUTH0_SECRET>',
    authorization_params= {
      redirect_uri: '<AUTH0_REDIRECT_URI>',
    }
)

The AUTH0_DOMAIN, AUTH0_CLIENT_ID, and AUTH0_CLIENT_SECRET can be obtained from the Auth0 Dashboard once you've created an application. This application must be a Regular Web Application.

The AUTH0_REDIRECT_URI tells Auth0 what URL to use while redirecting the user back after successful authentication, e.g. http://localhost:3000/auth/callback. Note: your application needs to handle this endpoint and call the SDK's complete_interactive_login(url: string) to finish the authentication process. See below for more information.

The AUTH0_SECRET is the key used to encrypt the session and transaction cookies. You can generate a secret using openssl:

openssl rand -hex 64

3. Add login to your Application (interactive)

Before using redirect-based login, ensure the redirect_uri is configured when initializing the SDK:

auth0 = ServerClient(
    # ...
    redirect_uri='<AUTH0_REDIRECT_URI>',
    # ...
)

[!IMPORTANT]
You will need to register the AUTH0_REDIRECT_URI in your Auth0 Application as an Allowed Callback URLs via the Auth0 Dashboard.

In order to add login to any application, call start_interactive_login(), and redirect the user to the returned URL.

The implementation will vary based on the framework being used, but here is an example of what this would look like in FastAPI:

from fastapi import FastAPI, Request, Response
from starlette.responses import RedirectResponse

app = FastAPI()


@app.get("/auth/login")
async def login(request: Request):
    authorization_url = await auth0.start_interactive_login()
    return RedirectResponse(url=authorization_url)

Once the user has successfully authenticated, Auth0 will redirect the user back to the provided redirect_uri which needs to be handled in the application.

This implementation will also vary based on the framework used, but what needs to happen is:

• register an endpoint that will handle the configured redirect_uri.
• call the SDK's complete_interactive_login(url), passing it the full URL, including query parameters.

Here is an example of what this would look like in FastAPI, with redirect_uri configured as http://localhost:3000/auth/callback:

@app.get("/auth/callback")
async def callback(request: Request):
    result = await auth0.complete_interactive_login(str(request.url))
    # Store session or set cookies as needed
    return RedirectResponse(url="/")
