Accessing Your MWS Amazon Seller ID & AuthToken

NOTE: THE STEPS BELOW ARE FOR THE NEW SYNCCENTRIC PLATFORM

*** For China, India, and Japan locales, please continue instructions here ***

Step 1: Accessing Your Amazon MWS Seller/Merchant ID & MWSAuthToken:

To get your Amazon MWS Seller ID & MWSAuthToken, you must sign up to MWS. To register for Amazon MWS, sign up using the appropriate link for your locale:

US: http://developer.amazonservices.com
CA: http://developer.amazonservices.ca
UK: http://developer.amazonservices.co.uk
DE: http://developer.amazonservices.de
FR: http://developer.amazonservices.fr
IT: http://developer.amazonservices.it
ES: http://developer.amazonservices.es

Click Sign up for MWS and then log in to your MWS account – or register if you don’t have a MWS account (you must have a Amazon Pro Seller account to register with MWS). Note, if it’s your first time registering, on your first login it may send you to your Amazon seller account; if this happens, just go back to the “Sign up for MWS” button using the link above and it will redirect you to the page displayed below:

Select ‘I want to use an application to access my Amazon seller account with MWS.‘ as shown by the screenshot below.
Application name: synccentric
Input ONE of the two developer account numbers below, depending which locale you are using…
NA Developer Account Number: 9686-0980-9446 (Required for Amazon US [.com] or CA)
EU Developer Account Number: 1784-4300-6592 (Required for Amazon DE, ES, FR, IN, IT, or UK)
Click Next.

Agree to the terms on the next page to continue.

Copy & save your ‘Seller ID’ and ‘MWSAuthToken’. You do not need to save the ‘Marketplace ID’, just know which locale your MWS account is, i.e. US, CA, UK, DE, FR, IT, or ES):

Step 2: Storing Your Amazon ‘Seller ID’ & ‘MWSAuthToken’ in your Synccentric Account:

Save the ‘Seller ID’ & ‘MWSAuthToken’ in your Synccentric account under ‘Manage Campaigns -> Edit’ or click the warning link that should display on your account for not having the ID stored. On the same page, select the correct locale (Amazon marketplace), custom name your campaign, then click Save.

Note: The Seller ID is required for faster conversions and the Auto Buy Box feature. We do not require that you have one, however it may dramatically slow your conversions down and limit you from certain features. The Seller ID is REQUIRED for Enterprise level packages due to the significantly high data limits we allow on those accounts.
