So you competed the Amazon MWS authorisation steps but you are getting the error below when clicking on the TEST button.
WHY AM I GETTING THE ERROR FEED REJECTED
Response Status: 400
Error Message by Amazon: Feed rejected
ERROR: You are getting this error from Amazon because either your Amazon account is brand new, or your account has become inactive.
What does this mean?
You are getting this error from Amazon because either your Amazon account is brand new, or your Amazon account has become inactive for some reason.
To resolve this issue please login to your Amazon account and re-submit your credit card information and your banking financial details.
We have observed that this error usually goes away after 2 to 3 days after re-submitting the financial details to Amazon, which triggers the account to be re-activated.
If you just opened a new Amazon Professional Seller account, then you should also perform the task above and wait 2 to 3 days to allow Amazon to complete the setup of your new account. Only then will you be able to have a successful test.
If you still experience an error after completing this task and after waiting a few days, then please contact us so we can further assist you.
