Kindle Digital Delivery API

I am trying to understand how the current https://kindle-digital-delivery.amazon.com/delivery/manifest/kindle.pdoc/<ASIN> API from Amazon works because I would like to be able to get the embedded id of a personal document stored on my amazon account and get the reading progress from those documents.

I tried to understand the protocol and it looks like you have to obtain a token and then use that token to perform the calls, nothing fancy so far.

Registering a device works, obtaining a token works, but then when I invoke that end-point I get an error that references a DeviceTokenInfo being invalid. This is where I am stuck as I have no idea what is going wrong.

Has anyone stumbled on this problem already and knows how to move forward?

Thanks!
