If you're having trouble connecting to the Amazon API, which is where you are redirected to Amazon and prompted to login, please see if any of the following reasons may apply to you.

  1. You have a shared email across EU and US accounts.

    A while back, Amazon enforced users to have one email address for their EU accounts and another for their US/CA accounts.  In the last few months Amazon allowed you to "join" these two email addresses to be able to access EU and US/CA/MX marketplaces from a single login.  Amazon have informed us that whilst this joins accounts for Seller Central it does NOT join accounts for their API.

    As such please login using the original email you signed up with for that marketplace e.g. if you signed up with [email protected] for EU and [email protected] - when connecting a EU account use [email protected] , an for US use [email protected].

  2. You are not running and PPC campaigns

    Amazon's API will only connect when you have at least one Advertising Campaign active.  If you have a new account, we would suggest you add one Campaign via Seller Central and then try to connect again.

  3. The user you are connecting with does not have permissions to manage PPC.

    If the user who is logging in is NOT the main account holder, they may not have permissions to access your PPC.  Please ensure the user is either the main account holder or has the correct permissions.

If any of above does not apply please do get in touch.
