 * After entering my access key, secret access and associate ID I get the following
   message:
    Failed authentication. Error: RequestThrottled: AWS Access Key ID: ******************.
   You are submitting requests too quickly. Please retry your requests at a slower
   rate. Locale: US Domain: webservices.amazon.com
 * But as I’m only trying once every few minutes, I don’t see how this can apply.
 * Ideas?

 * Hi,
 * As of Oct 31, 2019, Amazon ended PA-API 4 and now we have to use PA-API 5. Your
   keys may not be compatible with the new API version. So I suggest you reissue
   your keys and then try again.
 * With the new version of Amazon Auto Links 3.9.0, you can check the error by going
   to Dashboard -> Amazon Auto Links -> Tools -> Error Log. Then you can tell what
   error you get. If you get one, post the error message here.
 * Hope it helps.
