SPA + User Profile + Custom API

Hi everyone,

I’m looking at the quickstarts and I’m interested about the SPA + API.
But I can’t understand with Auth0 How I can manage the user profile management and a call at the same time to a custom API. But I’m a little bit disapointed bcause in the quickstarts we have an audience already set to get user profile, so I cannot call y custom API with a different identifier (audience).

Does anyone as an example ? Or an idea ? Am i missing something ?
