Hello Adam,
There is a limit on frequency you can request AuthToken at. If you request it too often, you will get a CAPTCHA challenge. This is required for security and not limited to the AdWords API. According to the 'Best Practices' you should be caching and re-using the token instead of requesting it every time. The token is valid for two weeks so you should only be requesting it once it's expired. See: http://code.google.com/apis/adwords/docs/bestpractices.html#auth_tokens You may also want to utilize OAuth authentication schema which allows you to have a token that never expires (unless revoked). -Danial, AdWords API Team. -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and discussion group: http://adwordsapi.blogspot.com http://groups.google.com/group/adwords-api =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
