Okta Flask Integration
I want to protect my Flask REST endpoints using Okta and OpenID connect.
I have seen how to do it for routes that are views of the application, but is there a way to integrate Okta with REST endpoints? When I make calls to my API, I get the html for Okta as a response, even if I'm logged in in the browser.

Hi Junnu, to get Responses from Okta, you need it to configure. it easy as Routes. Iam providing an article on Okta Training Tutorial. in this article you will know how to integrate Okta with REST.


Thanks for the topic of this article, let me share it with everyone. And I want to share a little bit about entertainment games.

Yes, it is possible to protect your Flask REST endpoints using Okta and OpenID Connect. To do this, you can use the Okta JWT Verifier library to verify the access tokens provided by Okta in your REST API calls. Here's an overview of the steps you'll need to follow:
- Configure your Okta application to use OpenID Connect and ensure that you have set the proper audience and scopes for the access token. You'll need to update the Redirect URIs and Logout URLs of your application with the endpoint of your REST API.
- In your Flask REST API, add the
flask_jwt_extended
andokta_jwt_verifier
libraries to your project.flask_jwt_extended
will be used to protect your endpoints andokta_jwt_verifier
will be used to verify the access tokens provided by Okta. - Initialize the Okta JWT Verifier library by specifying your Okta issuer URL and audience.
- Protect your endpoints using the
@jwt_required
decorator provided byflask_jwt_extended
. This decorator will ensure that only authenticated users with a valid access token can access your protected endpoints. - In the protected endpoint, use the
get_jwt_identity()
function provided byflask_jwt_extended
to get the user identity from the access token. This function returns thesub
claim of the JWT, which is the unique identifier of the authenticated user.
from flask import Flask, jsonifyIn this example, the
from flask_jwt_extended import JWTManager, jwt_required, get_jwt_identity
from okta_jwt_verifier import JWTVerifier app = Flask(__name__)
app.config['JWT_SECRET_KEY'] = 'mysecretkey'
app.config['JWT_ACCESS_TOKEN_EXPIRES'] = 3600
jwt = JWTManager(app) verifier = JWTVerifier({
'issuer': 'https://{yourOktaDomain}/oauth2/default',
'audience': '{yourOktaClientId}'
}) @app.route('/api/protected')
@jwt_required
def protected():
user_id = get_jwt_identity()
# Do something with the user_id
return jsonify({'message': 'This is a protected endpoint.'}) @app.route('/')
def home():
return 'Hello, world!' @app.before_request
def verify_jwt():
if 'Authorization' in request.headers:
token = request.headers.get('Authorization').split(' ')[1]
verifier.verify_access_token(token)
else:
abort(401) if __name__ == '__main__':
app.run()
@jwt_required
decorator is used to protect the /api/protected
endpoint. The get_jwt_identity()
function is used to get the user identity from the access token. The verify_jwt()
function is used to verify the access token in each request header, and will return a 401 error if the token is invalid. Note that the verify_jwt()
function is using Flask's before_request
decorator to run the verification code for each request. This ensures that every request to the API endpoint is validated.
