Authentication in Postman

To authenticate in Postman, create a new request

POST <https://aeropost-dev-stage.cloud-iam.com/auth/realms/core/protocol/openid-connect/token>

Body x-www-form-urlencoded

client_id = test_client  
client_secret = ut1tKa1EVlVCg6Mx5daKYhhaQMPHix1l  
grant_type = password  
username = test  
password = test_password  
scope = openid

You may add this code to automatically save to {{token}} Postman variable every time you hit the auth endpoint. Put this in "Tests" in the same request window.

let res = pm.response.json();  
pm.collectionVariables.set('token', res.access_token);

Once you get a token you can hit the Core app endpoints like 127.0.0.1/api/test by placing {{token}} variable under "Authorization > Bearer Token" in Postman
