Yes. In all cases the prerequisite is that the SKU on the marketplace matches the article number in your shop, and that under "Global Configuration" > "Synchronization of number ranges" the setting "Article number (Shop) = SKU (Marketplace)" is selected.

Products not created via magnalister are synchronized: yes (eBay) | yes (OTTO) | yes (Kaufland)

Additional setting required: "Synchronize third-party items" set to "Yes" (eBay) | none (OTTO) | none (Kaufland)

Refunds via magnalister: yes (eBay) | no (OTTO) | no (Kaufland)

Exclude individual products from synchronization: no (all marketplaces)

Please note:

• OTTO: Products newly created on OTTO are not recognized immediately, but with the next synchronization of the product list.
• Kaufland: Offers using Fulfillment by Kaufland are not included — only offers you ship yourself.
• Refunds cannot be issued through magnalister for OTTO and Kaufland. Please use the respective marketplace backend for this.
• Excluding individual products from synchronization is not supported. Synchronization always covers all products whose SKU can be matched.
