Add the application’s registration information to your App

In this step, you need to configure the Redirect URL of your application registration information and then add the Application ID to your JavaScript SPA application.

Configure redirect URL

Configure the Redirect URL field with the URL for your index.html page based on your web server, then click Update.

3. Paste the value as a Redirect URL on the top of this page, then click Update

Setting Redirect URL for Python

For Python, you can set the web server port via command line. This guided setup uses the port 8080 for reference but feel free to use any other port available. In any case, use the following instructions to set up a redirect URL in the application registration information:
Set http://localhost:8080/ as a Redirect URL on the top of this page, or use http://localhost:[port]/ if you are using a custom TCP port (where [port] is the custom TCP port number), and then click 'Update'

Configure your JavaScript SPA application

1. Create a file named msalconfig.js containing the application registration information. If you are using Visual Studio, select the project (project root folder), right-click and select: Add > New Item > JavaScript File. Name it msalconfig.js
2. Add the following code to your msalconfig.js file:

var msalconfig = {
    clientID: "[Enter the application Id here]",
    redirectUri: location.origin
};
