M2E Pro Extension must be granted with SP-API tokens to be able to interact with Amazon. The user token represents authorization for the application to access Amazon data on behalf of an Amazon user.
The Extension allows granting and using an unlimited number of SP-API tokens for Amazon accounts.
A separate account must be configured in M2E Pro for every Amazon marketplace you sell on. It is required to set up inventory and order synchronization between Extension and appropriate marketplace.
When you start working with M2E Pro, you will be able to create your first Amazon account.
If you need to connect another account, navigate to Amazon Integration > Configuration > Accounts and click on the Add Account button.
Or connect the account via the Add button at the first step of M2E Pro Listing creation.
