Python Flask Quickstart to Protect Your API

This repository contains a sample of extending Okta authentication using the redirect model in a Python Flask app to protect the API.

Read more about getting started with Okta and authentication best practices on the Okta Developer Portal.

This code sample demonstrates

• Configuring Okta
• Sign-in and sign-out
• Protecting routes
• Displaying user profile information from the ID Token

Prerequisites

Before running this sample, you will need the following:

• The Okta CLI Tool
• An Okta Developer Account (create one using okta register, or configure an existing one with okta login)

Get the Code

Grab and configure this project using okta start flask-api.

Follow the instructions printed to the console.

Run the Example

To run this application, install its dependencies:

pip install -r requirements.txt

With variables set, start your app:

python3 -m flask run --port=5000

Navigate to http://localhost:5000 in your browser.

If you see a home page that prompts you to login, then things are working! Clicking the Log in button will redirect you to the Okta hosted sign-in page.

You can sign in with the same account that you created when signing up for your Developer Org, or you can use a known username and password from your Okta Directory.

Note: If you are currently using your Developer Console, you already have a Single Sign-On (SSO) session for your Org. You will be automatically logged into your application as the same user that is using the Developer Console. You may want to use an incognito tab to test the flow from a blank slate.
