Javascript - Logging In with SSO

This example uses MSAL.js v1.x and the Implicit Grant flow:

https://docs.microsoft.com/en-us/azure/active-directory/develop/msal-js-initializing-client-applications

Please ensure your App Registration in Azure AD has the following options configured:

Implicit Grant

[ x ] Access tokens

[ x ] ID tokens

OR in the manifest file:

"oauth2AllowIdTokenImplicitFlow": true,
"oauth2AllowImplicitFlow": true,

Redirect URIs

You will need to enter the exact url or the html page requesting the login.

Authentication → Single-page Application → Redirect URIs

OR in the manifest file:

    "replyUrlsWithType": [
        {
            "url": "https://examplesite.azurewebsites.net/index.html",
            "type": "Spa"
        }]

Please update the ClientId and CxApiUrl to suit you configuration below:
