Does Prestozon support KDP (Kindle Direct Publishing) for authors?

The answer is - sort of. We do the best we can with the limited data that Amazon gives us, but we don't report on page reads and other important author-specific fields.

KDP is part of AMS and we do receive data from KDP accounts. However, Amazon doesn't send us any of the author-specific data fields, including Kindle page reads. So while you will be able to see some of your data, it will be incomplete. 

Amazon also does not differentiate KDP accounts from other AMS accounts, so Prestozon has no way to know whether an account is KDP or not. 

This will be true for all software services that use Amazon's APIs, unfortunately. We do not know when of if Amazon will start providing more author data, but we do not believe it is their current focus.
