Problem redirect getting authorization token

[luisEnriqueR]

When i try to run the example of the authorization code it redirect me into a login page like this one:
https://www.mercadolibre.com/jms/mla/lgz/login/?go=https%3A%2F%2Fauth.mercadolibre.com.ar%2Fauthorization%3Fclient_id%3D479%26redirect_uri%3Durl.com.ar%26response_type%3Dcode&platform_id=ml&application_id=479939650732
This one contains fake parameters, but is where https://auth.mercadolibre.com.ar/authorization requesting this url leads me.
Is there a way to make that login with a request?
For the moment i solved it using Selenium, but i think is no the best way.
