Update: In preparation for deprecating the seller version of PA-API, some users may notice that they are being throttled to the point that they cannot continue using it. The throttling will produce a blacklisting error. This is happening to users who have not complied with the repeated attempts to contact them and ask them to identify the seller accounts they are using the PA-API data for. Many users have AWS accounts that do not directly map to seller accounts; these are the accounts that are affected. Only valid Amazon sellers may continue to use PA-API until the end of August.
If you have a valid, unblocked, Amazon paid subscription seller account that has active offers and recent sales, and the AWS key that you’re using for PA-API is not tied to this seller account, and you did not comply with the request back in May to contact us and allow us to make the connection between the two accounts, you will likely be blocked in the coming days. This is an attempt to persuade you to contact us and acknowledge that you are aware of the upcoming final shut down of PA-API for sellers on 8/31/2012.
If you are an Amazon Associate, you should be using the Associate version of PA-API, which is not shutting down. For information, go here: https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html
If you are experiencing problems, or if you’re not sure whether you will be impacted, please contact us. If you have valid Amazon seller usage, let us know; we will restore your access for the remainder of August. Here are the MWS portals for the affected regions. Just click on the contact link on the left-hand navigation pane, sign in with your valid seller account, and tell us your AWS key that you’re using to access PA-API. We will reply within one business day.
