How to Buy Shipping Labels Through Amazon's SP-API
Amazon's Buy Shipping API lets Professional sellers purchase shipping labels programmatically through the SP-API, either via custom integrations or established shipping software providers across multiple global marketplaces.
Overview
Amazon provides sellers with the ability to purchase shipping labels programmatically through the Selling Partner API (SP-API). This feature allows Professional sellers and their development partners to automate the shipping workflow, reducing manual effort when fulfilling merchant-fulfilled orders. Whether you build your own integration or work with an established shipping software provider, the Buy Shipping API can streamline your fulfillment operations at scale.
Key Points / What Sellers Need to Know
- Professional plan required — The Buy Shipping API is only available to sellers enrolled in Amazon's Professional selling plan. Individual sellers cannot access this feature.
- SP-API developer registration — Before using the API, you (or your developer) must register as an SP-API developer and then register your SP-API application through Amazon's developer portal.
- Multiple integration paths — You can build your own custom shipping application, use a third-party shipping integrator that supports the API, or purchase shipping services directly through the SP-API.
- Multi-marketplace support — The Buy Shipping API is available across multiple Amazon marketplaces including the United States, United Kingdom, Germany, France, Italy, Spain, Canada, Japan, and several others.
- Terms and conditions apply — Use of the Buy Shipping API is governed by Amazon's Business Solutions Agreement, which all registered sellers have already accepted.
How It Works
The Buy Shipping API allows sellers to programmatically purchase shipping labels for their merchant-fulfilled orders without logging into Seller Central manually. Developers build applications that connect to the SP-API, retrieve order details, request shipping rate quotes, and purchase labels — all through automated code. This is especially valuable for high-volume sellers who process dozens or hundreds of orders daily, as it eliminates the need to manually navigate the Buy Shipping workflow in Seller Central for each individual order. Amazon's SP-API documentation provides detailed technical guidance on how to fulfill orders in each marketplace.
Analysis & Recommendations
Why This Matters
Merchant-fulfilled sellers processing high order volumes can significantly reduce manual work by automating label purchases through the API, and the growing list of compatible integrators makes this accessible even without custom development.
