Mapping BE API with JWT Authentication

Hi everyone, i try to use KONG v. 1.1.2 and i need to expose my BE API

my scenario is:

BE API with authentication via JWT TOKEN, that emitted when you perform the login
KONG to expose it
and Curl command to simulate client

But i can’t loggin,

My idea was, I need configure a Consumer that receive in session jwt token to use when try to consume my service,

how i can configure it?

someone have idea?

I try to use JWT plugin, but if i understand that plugin make a token, not accept token form BE API.

thenk for any support, any help will be appreciate.
