SellerSpace allows you to seamlessly manage multiple Amazon stores without any risk of account association. This is made possible by our highly secure data acquisition method: Amazon’s latest Selling Partner API (SP-API) authorization.

SP-API is Amazon’s officially recommended method for data integration, enabling third-party software providers to securely and reliably retrieve seller store data.

With SellerSpace accounts, you can authorize multiple Amazon stores. However, each Amazon account can only be authorized to a single SellerSpace account and cannot be authorized to multiple SellerSpace accounts.

There are two authorization methods: Amazon Appstore Authorization + SellerSpace System Authorization. For both authorization methods, ensure that the IP address is consistent during the process. When authorizing your store and advertising, please ensure that the computer and IP address currently logged into SellerSpace are your usual environment for logging into this Amazon account to prevent account association.
