I'm looking for the APIs that will let me manipulate my purchases into/out of Collections, group by author, and eventually to rate & link out to the actual store for more by that author. It's for personal use at this stage because their interface is godawful. The API, if it exists, isn't promoted in their developer section. Has anyone got any experience with this? ref: https://developer.amazon.com/blogs/tag/OAuth+2.0 https://sellercentral.amazon.com/fo...-to-get-amazon-order-details-for-users/124834
