8. Highlight and copy your Seller ID. If you have a unified Europe account where you sell on the UK site but DE, FR, IT and ES are all linked, then you only need the one main Seller ID for all of them - NOT the individual Marketplace ID, so please ignore the Marketplace IDs.

10. Return to Amazon and highlight and copy your MWS Authorisation Token, then paste this into the corresponding field in ChannelGrabber:

This will add your Amazon account into ChannelGrabber so that you can list to Amazon and ChannelGrabber can manage stock and pull in your Amazon orders. Please note that stock management is not automatically set live on new accounts, so you may need to discuss this with your implementations specialist or the Support Team.
12. To import your Amazon listings, please follow the Unimported Listings guide in the knowledgebase.
