Hi Kasia, You get a captcha required error if you generate authtokens very frequently. AuthTokens are long-lived, and so are expected to generate an authtoken once and reuse it until it expires. See http://adwordsapi.blogspot.com/2010/07/discover-v2009-working-with-authtokens.html for an article that discusses the best practices on using auth tokens.
