A matching key is the field two systems use to recognize that a record refers to the same product – for example the item number, SKU, EAN/GTIN or manufacturer part number. Every system brings its own key: Shopify matches on the handle during CSV import, Shopware works internally with IDs, suppliers send their own item numbers. If the keys do not match, duplicates appear or updates go nowhere – which is why every integration starts with deciding which key leads. In a PIM, the matching key is the basis for merging data from several sources into one golden record per product.
