The Amazon MWS authorizations that grant developer access to seller data will be subject to annual review and renewal by sellers.
What this means is your link to FeedbackExpress will need to be reapplied each year. You will receive notification from Amazon one month before the date the authorisation expires. If no action is taken the token will be deactivated on the expiration date.
When an authorisation token expires, it is simply deactivated but not invalidated. You can always renew an expired authorisation token.
Once renewed the expiration date resets to one year from the date of renewal.
We will also send you an email notification as well. Around this time you will see a notification on your FeedbackExpress dashboard:
If you click on the review now button, you will be taken to your 'Channels' screen where you will see the channels will be un-linked
All you need to do is click on the 'Relink Required' text and you will be taken through the steps to relink your account. Once done you will be all set for another year.
If you run into any problems do not hesitate to get in contact with our support team directly.
