My API Credentials Don’t Work

Troubleshooting & FAQ Troubleshooting & FAQ Windows 2 years ago

Amazon MWS API credentials are required for to access data from the Amazon API. These credentials are found in Amazon Seller Central and require a professional seller account.  Analyzer.Tools pulls all data for its fee calculator directly from Amazon using these credentials.

Invalid API credentials errors can have a limited number of reasons, which are listed below:

  1. Credentials are incorrectly entered into program, please be sure to follow our instructions in this article. Do not use credentials from an old program,
  2. You selected the wrong region link to generate your credentials. Be sure you selected North America (includes Canada, US, and Mexico) or Europe (includes Spain, UK, France, Germany, and Italy) correctly under step 1 of this article. If unsure, generate the keys again by clicking the correct region link and try again,
  3. Credentials are invalid if you a) do not have an Amazon professional seller account, or b) your professional seller account is not in good standing or c) your professional seller account is new and pending verification,
  4. Internet connection or Amazon API downtime issue (very rare).

Once you enter your credentials into the program, click “test” and look for a “Success” message.
