Can AutoPPC apply changes to Amazon directly?
This answer describes a capability that is partial today. What follows states exactly where the line is.
Direct Amazon API apply is not available in the current beta. On a paid plan, you approve proposals in Review, download the Amazon bulk file for the selected marketplace, and upload it yourself.
AutoPPC keeps the exact exported file and its matching Reverse file. A later read-only pull checks whether the expected changes are present. Exporting a file is not evidence that it was uploaded successfully.
Use the supported manual-upload workflow. No automatic submission is promised.
