User token to request API externally


Auth0 is a very new technology for me, and I have some troubles to use it for my use case.

I build an ExpressJS API and successfully implemented authentication to my middlewares.

I have a front app who will call this API, and I saw a lot of documentation, so this will be ok.

My problem is that I want some of my users to directly call the API, but I can’t find how to generate a token for specific users. For example, I tried to use postman to request my API but since the token is not a user token I can’t access middleware secured for specific permissions (i get “403 - Insufficient scope error”)

I think I am not fully understating all the concept of app and API in auth0. If so, I’ll be happy to have some advices.

Thanks in advance,
