Spark Login from Paw / Postman API Tool

Hey there!

I am a pretty new dev and working on my first bigger site based on Laravel that also uses Spark.

I would like to test several non-public API calls as logged in user from an API tool (I use Paw). How can I do a login or simulate a logged in / authorised Laravel user from an API tool?

Thanks for help or pointing to a helpful resource. I had trouble finding the right documentation. Aaron
