'Access AzureAd registered API from a B2C registered Web App

We have an Azure AD B2C registered web app and an Azure AD registered Web API - is it possible to make authenticated calls to the Azure AD Web API from the Azure B2C Web app? Can it be done?

We have tried a few different ways but not having much luck - including Access Control Lists but it doesn't accept the token passed as says it is invalid.

You must register two applications in the Azure AD B2C directory to enable your app to sign in with Azure AD B2C and call a web API.

  • Your app can sign in with Azure AD B2C via the web, mobile, or SPA application registration. The Application ID, also known as the client ID, is generated during the app registration process and uniquely identifies your application (for example, App ID: 1).

  • Your app can use the web API registration to call a protected web API. - The web API permissions (scopes) are exposed as part of the registration . The Application ID is generated during the app registration process, and it uniquely identifies your web API (for example, _App ID: 2 ).
