This is the seed project you need to use if you're going to create an API using FastAPI in Python and Auth0. If you just want to create a Regular Python WebApp, please check this project

In order to run the example you need to have python3 (any version higher than 3.6) and pip3 installed.

The configuration you'll need is mostly information from Auth0, you'll need both the tentant domain and the API information.

This app reads its configuration information from a .env file by default.

To create a .env file you can copy the .env.example file and fill the values accordingly:

cp .env.example .env

Alternatively you can use environment variables to define your application's settings (remember to update the values accordingly):

export AUTH0_DOMAIN='your.domain.auth0.com'
export AUTH0_API_AUDIENCE='your.api.audience'
export AUTH0_ISSUER='https://your.domain.auth0.com'
export AUTH0_ALGORITHMS='RS256'

Once you've set your environment information below you'll find the commands you'll need.

1. Create and activate a python environment:

python3 -m venv .venv
source .venv/bin/activate

2. Install the needed dependencies with:

pip install -r requirements.txt

3. Start the server with the following:

uvicorn application.main:app

4. Try calling http://localhost:8000/api/public

curl -X 'GET' \
  'http://localhost:8000/api/public' \
  -H 'accept: application/json'

Access http://localhost:8000/docs. From there you'll see all endpoints and can test your API

You can then try to do a GET to http://localhost:8000/api/private which will throw an error if you don't send an access token signed with RS256 with the appropriate issuer and audience in the Authorization header.

curl -X 'GET' \
  'http://localhost:8000/api/private' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer  <FILL YOUR TOKEN HERE>'

You can also try to do a GET to http://localhost:8000/api/private-scoped which will throw an error if you don't send an access token with the scope read:messages signed with RS256 with the appropriate issuer and audience in the Authorization header.

curl -X 'GET' \
  'http://localhost:8000/api/private-scoped' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer  <FILL YOUR TOKEN WITH SCOPES HERE>'
