Mapping links a catalog product to a channel listing. Once mapped, inventory and price push out to the channel, and orders pull back in — keyed by SKU. Without a mapping, a product simply doesn’t sell on that channel.

The two ways to map

Match existing — if the item already exists in the channel’s catalog (a known ASIN on Amazon, an existing eBay listing), match your SKU to it by identifier (UPC/EAN/GTIN/ASIN). You sell on the existing detail page.

Create new — if no listing exists, create one. You’ll choose the channel’s category/product type and fill its required attributes — most of which pull from your catalog attributes automatically.

How sync works once mapped

• Inventory & price push from catalog → channel on change and on schedule.
• Orders pull from channel → your unified inbox.
• Everything keys off SKU, so SKU stability is essential.

⚠️ Warning: The #1 cause of sync problems is a SKU mismatch between the catalog product and the mapped listing. If quantities or prices look wrong, check the mapping first.

Variants

Mapping happens at the variant/SKU level, not the parent product. Each variant maps to its own listing/offer.
