Hi, CAPTCHAs can appear for various reasons when our automated systems believe that the requests are behaving in a suspicious way. One of the reasons could be that the tool is performing authentication many times in a short period of time instead of retrieving a single authentication token to be reused in all requests.
If you exceed the rate of messages per hour and per day you don't get a CAPTCHA, but instead the calls return with a 503 response code, which asks you to slow down the requests. Hope it helps Claudio On Mon, May 30, 2011 at 11:09 AM, febs <[email protected]>wrote: > Hello, > We are testing the Emailchemy tool ( > http://www.weirdkid.com/products/emailchemy/ ) to migrate our user's > emails to google Apps. > After loads of emails uploaded successfully for hundreds of users, > Emailchemy started to log that a captcha was required: > > com.google.gdata.client.GoogleService$CaptchaRequiredException > > We asked the developer about this, and he suggested that maybe we are > exceeding the rate of messages per hour and per day.
