This Python code sample demonstrates how to implement authorization in a Flask API server using Auth0.

Create a virtual environment under the root project directory:

macOS/Linux:

python3 -m venv venv

Windows:

py -3 -m venv venv

Activate the virtual environment:

macOS/Linux:

. venv/bin/activate

Windows:

venv\Scripts\activate

Install the project dependencies:

pip install -r requirements.txt

Create a .env file under the root project directory and populate it with the following content:

CLIENT_ORIGIN_URL=http://localhost:4040
AUTH0_AUDIENCE=
AUTH0_DOMAIN=

Run the project in development mode:

flask run

The API server defines the following endpoints:

GET /api/messages/public

Status: 200 OK

{
  "message": "The API doesn't require an access token to share this message."
}

GET /api/messages/protected

Status: 200 OK

{
  "message": "The API successfully validated your access token."
}

GET /api/messages/admin

Status: 200 OK

{
  "message": "The API successfully recognized you as an admin."
}
