Recently, Amazon has introduced a new set of APIs, called SP-API. The old APIs, called MWS APIs, will soon be discontinued.
The Shipr FBA Amazon app was built on top of the old MWS APIs. Now, we are migrating the app to the new SP-APIs.
To ensure a seamless transition to the new APIs, you will need to authenticate your Amazon account by clicking the 'Connect Now' button and linking the Amazon account.
If the new APIs are not linked by July 31, 2022, the app will not be able to connect to your Amazon Seller account and stop working.
