Hello,

If your product SKUs in Linnworks match marketplace SKUs, you could use the Link all by SKU option:

This is the quickest way to do it and would map all matching SKUs.

Otherwise, it can be done with an import so a file would need to be prepared with the mapping data and imported into the system. Stock Item Linking is the name of the import, you can find more details and an example file here - https://assets.linnworks.com/support/settings/import-and-export-data/import-data/import-types/stock-item-linking-import
