Overview

In August 2023 Amazon expanded its Selling Partner API (SP‑API) documentation by adding six ready‑to‑use code samples for the Merchant Fulfillment API. The new examples walk developers through the most common fulfillment actions—creating shipments, updating status, and retrieving details—so sellers can jump straight into production code instead of building from scratch. The release is aimed at shortening integration time, cutting down on mistakes, and enabling faster time‑to‑value for Amazon sellers.

Key Points

• Six new Merchant Fulfillment samples — The update publishes six distinct code snippets that cover the core fulfillment operations, such as creating a shipment, updating shipment status, and retrieving shipment details.
• Step‑by‑step walk‑throughs — Each sample explains the purpose of the API call, required request parameters, and how to interpret the response, making the learning curve smoother.
• Embedded in SP‑API docs — The code blocks live directly in the developer portal, allowing developers to copy, paste, and run them in their own environment with minimal setup.
• Reduced integration effort — By providing pre‑written logic, sellers avoid the initial boilerplate and can focus on tailoring the workflow to their business rules.
• Immediate credential validation — Running the samples confirms that the seller’s SP‑API credentials, scopes, and network connectivity are correctly configured.
• Best‑practice templates — The samples demonstrate proper authentication, error handling, and response parsing, serving as a reference for future custom code.

How the SP‑API Code Samples Work

1. Locate the samples — Open the SP‑API developer portal, navigate to the Merchant Fulfillment section, and click the “Code Samples” tab. The six examples are grouped by operation and labeled with the exact API method name.
2. Read the description — Each sample starts with a concise overview of the operation, followed by a code block that shows the exact request payload. The description explains the required authentication headers, the JSON body structure, and any optional fields.
