Amazon
Report-based imports, separate content and price/stock submissions, per-country taxonomy, and why submission success isn't listing success.
Amazon is both a source and a publishing target. It is not currently available as a price and stock source of truth.
Importing from Amazon
Products are pulled through Amazon's reports pipeline: a report is requested, Amazon prepares it asynchronously, and MarketplaceHub collects it when it is ready. Because that is a batch process rather than a live query, an import is not instantaneous — how long depends on Amazon's queue, not on catalog size.
Imported products carry the Amazon product type they were already filed under, so publishing back to Amazon in the same country skips classification entirely and costs no AI credits.
Publishing to Amazon
Listings are submitted as feeds. Content and price/stock go through separate submissions, which is what allows a stock change to be pushed without republishing a listing.
Amazon accepts a submission and validates it afterwards, so a successful submission is not yet a successful listing — the outcome arrives later and surfaces as a notification. Listings rejected at that stage are usually missing a field the product type requires; the field reference is the place to check what that product type expects.
Taxonomy
Amazon product types are imported per country on a recurring schedule. Amazon UK and Amazon DE are different taxonomies with different required fields, and are versioned independently — see Product types and taxonomy versions.
Identifiers
Amazon both ranks and gates on product identifiers, so supplying a barcode in your feed materially affects whether a listing is accepted. See the product feed format.
