Q: How much does it cost to use Amazon MWS?
There are no fees associated with Amazon MWS, but you need to have an Amazon seller account to use it.


Q: Can all Amazon sellers use MWS?
To be eligible to use MWS, sellers must have at least one of the following: a non-individual Selling on Amazon account, an Amazon Payments account, an Amazon Fresh account, or an Amazon Prime Now account. Sellers with only individual Selling on Amazon accounts are not eligible to register for or use MWS. If you are an individual seller and would like to use MWS, you can become eligible to register for MWS by upgrading to a Professional seller account from the
Amazon Services Selling on Amazon page.

Q: I have previously granted MWS access to my Selling on Amazon account to a third-party solution provider. How do I remove that access?

Q: I need my Seller ID, Marketplace ID, MWS Authorization Token, Developer Account Number, Access Key ID, and my Secret Key to use Amazon MWS. Where do I find these?
Visit the

On the row that includes your Developer ID, click View your credentials to find your AWS Access Key ID and Secret Key. To see a list of Marketplace IDs, visit Amazon MWS endpoints and MarketplaceId values.


Q: How do I sign up to use MWS for my own Amazon seller account?
Click the Sign up for MWS button on the first page of the MWS portal at
https://developer.amazonservices.com. You must be able to log into a Professional Amazon seller account in order to continue through the registration process.

Be sure to save these identifiers and credentials as you'll need them to make successful MWS requests.
