How to log into amazon associate page with mechanized

I want to scrape my associate data but I cant log into: https://affiliate-program.开发者_JAVA百科amazon.com/gp/associates/login/login.html

I have tried all the various methods offered by Mechanized without success. Amazon always returns me the login page.

I have looked and the Amazon API does not cover this feature.

Any ideas how to do this?
