While Google will handle support issues related to publishers' AdSense accounts, you should use your existing support model to answer customer questions related to your specific implementation of the AdSense API. As customers may contact Google for concerns about your API implemetation, you must provide Google with an email address to forward publisher issues. Google will provide first-level triaging of publisher issues and will escalate those associated with implementation issues to this email address. For AdSense account-related issues, we will provide you with a URL pointing to the AdSense Help Center; you may not publish any Google email addresses on your website.
