The core integration points here are as follows:
  • Direct users to the Civic Auth login page
  • Set up an endpoint that the auth server should redirect to once complete
  • Set up middleware to ensure only logged-in users can access protected parts of your app.
Use these guides to set up Civic Auth with any of the most common Python web frameworks.

​
Installation

Install the Civic Auth Python SDK using pip: 
pip install civic-auth
For framework-specific integrations: 
pip install "civic-auth[fastapi]"
If you’re using the uv package manager: 
uv add "civic-auth[fastapi]"

​
Usage

The Civic Auth Python SDK provides a flexible API that works with any Python web framework. For framework-specific integrations, see the guides above.

​
Getting User Information on the Backend

Here are some examples of using the get_user function in popular Python server environments. Note - this snippet assumes you have followed the steps to integrate login with your app as described here. 
from fastapi import Depends
from civic_auth.integrations.fastapi import create_auth_dependencies, create_auth_router

civic_auth_dep, get_current_user, require_auth = create_auth_dependencies(config)

@app.get("/admin/hello", dependencies=[Depends(require_auth)])
async def hello(user = Depends(get_current_user)):
    return f"hello {user.name}!"

​
Getting the Access Token

Use CivicAuth-managed storage to retrieve tokens. Prefer the SDK helper that exposes a CivicAuth instance and call await civic.get_tokens() (auto-refreshes when needed). If your endpoint receives a bearer token from a frontend, you can also read it from the Authorization header. 
# Preferred: via CivicAuth instance
tokens = await civic.get_tokens()  # { 'access_token': '...', 'id_token': '...', ... }
access_token = tokens["access_token"]

# Fallback: read bearer token from headers (example)
auth = request.headers.get("Authorization", "")
access_token = auth.removeprefix("Bearer ").strip()
