If you're a seller on a Professional selling plan, you can access Buy Shipping through the Amazon Marketplace Web Service, with the Merchant Fulfillment API. Amazon Marketplace Web Service enables developers to build applications that let sellers use Amazon's Buy Shipping outside of Seller Central.
You can also buy shipping labels by using an eligible third-party shipping integrator that has adopted Amazon's Merchant Fulfillment API. For many integrators, the process is as easy as one click.
If you are currently using a shipping integrator that is not listed, contact your integrator to find out if they have already adopted the API, or their timeline to adopt.
