How to validate Authentik Session on different machine

[timmske]

Hello everybody,

I am currently facing the problem on how to validate a session. But first my setup:

The login is managed by using the "default-authentication-flow", feeding the API with username and password. This works so far.

The question is, how do I validate that session on a different machine running a NestJS API Backend. I tried every possible approach I found online, starting with forwarding the cookies, set by Authentik after successfully logging in, to the API and making a request to /v3/core/users/me/ including these cookies, all the way to experimenting with JWT. None of that works.

There must be a simple approach for getting some sort of Bearer Token with the default-authentication-flow or am I wrong? What am I missing here?

I really hope somebody has an idea, because I am getting a little frustrated.

Thanks in advance!
