OAuth2 Code Flow Sample

This is a demo on how to get a token using the authorization code flow.
The code flow is the preferred flow, because it allows refreshing the token, so your app can use the API for a long time.
This page redirects you to the login website, to authenticate and retrieve a code.

The code flow requires a backend, so the app secret remains secret. This example contains two flavours, PHP and NodeJs.

Steps for PHP

  1. Setup a web server running PHP.
  2. Copy files from Github to "http://localhost/openapi-samples-js/authentication/oauth2-code-flow/redirect/".
  3. The redirect URL is now "http://localhost/openapi-samples-js/authentication/oauth2-code-flow/redirect/". Add this as redirect below.
  4. Optional: Create your own app with the redirect URL of your choice.
  5. Optional: If you've created your own app: modify server-config.php, so it contains the correct app key, secret and redirect URL.

Steps for NodeJs

  1. Clone this repository and navigate to \openapi-samples-js\authentication\oauth2-code-flow\redirect\backend-js\
  2. Get the required modules using "npm install".
  3. Launch the express web server with "node server.js".
  4. The redirect URL is now "http://localhost:1337/". Add this as redirect below.
  5. Optional: Create your own app with the redirect URL of your choice.
  6. Optional: If you've created your own app: modify server.js, so it contains the correct app key, secret and redirect URL.
