Api call in Postman

[foojr]

Hello everyone, I'm trying to do the remoteLock call in Postman with no success. I can get token, validate, connectCar and get cars information through MyAccountServlet with service:getOwnerInfoService but when I try a remoteAction I get an empty response with no action taken. It works fine with this python code, I just don't get it what am I missing here. I fill up the all headers according to the code and x-www-form-urlencoded body with username, pin, token (jwt), url, gen, regid and service.

There is any other source of documentation?

Any ideas is very much appreciated.
