Generate Google Client Config

Edit your settings.py file:

        ...
        "django_google_integrations"
)

# Django Google Integrations Config
GOOGLE_CONFIG = {
    "CLIENT_CONFIG_JSON": "[Google Client Config Json]",

    "CLIENT_SECRET": "[Google Client Secret]",
    "SERVICE_ACCOUNT_SCOPES": [
            "openid",
            "https://www.googleapis.com/auth/userinfo.email",
            "https://www.googleapis.com/auth/userinfo.profile",
        ],
    "REDIRECT_URI": "http://localhost:3000/google/auth/callback",
    "RESPONSE_HANDLER_CLASS": "example.testapp.google_response_handler.GoogleSigninResponseHandler",
}

Create Response Handler Class and update path in GOOGLE_CONFIG

from django_google_integrations.services import GoogleResponseHandler

class GoogleSigninResponseHandler(GoogleResponseHandler):
    def handle_fetch_or_create_user(self, flow, google_user_data):
        email = google_user_data.get("email", None)
        user = get_user_by_email(email)
        is_created = False
        if not user:
            user_dict = {
                "first_name": google_user_data.get("given_name", ""),
                "last_name": google_user_data.get("family_name", ""),
                "password": None,
            }
            user = create_user_account(email, **user_dict)
            is_created = True

        extra_context = {"is_created": is_created}
        return user, extra_context

    def generate_response_json(self, user, extra_context):
        response = AuthUserSerializer(user)
        return response.data

NOTE:

• AuthUserSerializer used in above ref. could be created as per app's functionality and contain fields which needs to be sent in response of authorization.

default_router = routers.DefaultRouter(trailing_slash=False)
default_router.register("auth/google", GoogleAuthViewSet, basename="google-auth")
