Client Applications

Instantiating an Application

Pre-requisites

Before instantiating your app with MSAL Python,

1. Understand the types of Client applications available- Public Client and Confidential Client applications.
2. You'll need to register the application with Azure AD. You will therefore know:
   • Its client_id (a string representing a GUID)
   • The identity provider URL (named the instance) and the sign-in audience for your application. These two parameters are collectively known as the authority.
   • Possibly the Tenant+id in the case you are writing a line of business application (just for your organization, also named single-tenant application)
   • In case it's a confidential client app, its application secret (client_secret string) or certificate
   • For web apps, you'll have also set the redirect_uri where the identity provider will contact back your application with the security tokens.

Instantiating a Public Client application

app = msal.PublicClientApplication(
    config["client_id"],
    authority=config["authority"],
    )

Instantiating a Confidential Client application

app = msal.ConfidentialClientApplication(
        config["client_id"],
        authority=config["authority"],
        client_credential=config["client_secret"],
        )
