question, i'm trying to learn kotlin for android (I'm a BRAND Spanking new mobile developer) How would I handle authentication against my rest end point?

moos3: Authentication as in user or API level?

so I have a api that I want to send my username and password to and have my web api end point return a json containing a JWT

Sure, so essentially just your regular POST request and parsing the JWT back as a string for example?

yeah

I see. You should look at networking libraries like Volley or Fuel which is written in Kotlin. Is your hashing using JWT too? They also have a Java SDK for that
