PythonVersion:

A Django REST framework authentication class for the ZGW API authentication pattern.

The ZGW Auth JWT includes claims for user_id and user_representation. This information can be used in your API to authenticate the actual end-user, even when using gateway APIs.

2 Features

• Authenticates the end-user based on the user_id JWT claim

• Follows the auth spec for “API’s voor zaakgericht werken”

3 Installation

pip install zgw-auth-backend

INSTALLED_APPS += ["zgw_auth_backend"]

python manage.py migrate

REST_FRAMEWORK = {
    "DEFAULT_AUTHENTICATION_CLASSES": [
        ...,
        "zgw_auth_backend.authentication.ZGWAuthentication",
        ...,
    ],
}

4 Usage

Specify the authentication class on your view(s):

from rest_framework import views
from zgw_auth_backend.authentication import ZGWAuthentication

class MyView(APIView):
    authentication_classes = (ZGWAuthentication,)

1. Add the client credentials in the admin (client ID + secret)

2. Generate a ZGW auth JWT with the user_id claim, using the credentials from step 1

3. Make an API call to the endpoint, including the Authorization: Bearer <jwt> header

4. Verify that the user with user_id username is created if it didn’t exist yet, or if it did, that request.user is now this user.
