Product Type Definitions API v2020-09-01 Use Case Guide

# What is the Product Type Definitions API?

Using the Selling Partner API for Product Type Definitions (Product Type Definitions API), you can search and retrieve Amazon product type definitions. Amazon product type definitions describe the attribute and data requirements for items in the Amazon catalog using JSON Schema.

For more details on the JSON Schema format provided by the Product Type Definitions API, see the accompanying Amazon Product Type Definition Meta-Schema (v1) (opens new window) documentation.

See the Product Type Definitions API Reference (opens new window) for details about API operations and associated data types and schemas.

Key Features

  • JSON Schemas: The Product Type Definitions API provides JSON Schemas that describe the seller-agnostic requirements for a given Amazon product type. This includes the data format, attribute constraints (i.e. required, length, maximum, etc.), and conditionally applied attribute constraints (i.e. if batteries are included, what type of battery).

  • Compatible with Open-Source Libraries: The JSON Schemas provided can be used with widely available open-source and commercial libraries, applications, and services to understand data requirements, create data mappings, generate user interfaces, and validate listings data before submission to Amazon.

  • Localized Presentation Details: The JSON Schemas provided include display labels and descriptions for attributes in any supported locale for any marketplace.

Terminology

  • JSON Schema: JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. See json-schema.org (opens new window) for more details.

  • Meta Schema: Meta schemas describe the vocabulary used by JSON Schema documents. For example, Amazon product type schemas include vocabulary for selectors and editable. This vocabulary is described in a meta schema, enabling libraries and applications to understand and validate JSON data based on these extensions to the standard JSON Schema vocabulary.

  • Product Type: An Amazon product type is a hierarchical categorization of items in the Amazon catalog. Item data requirements are tied to the associated product type of the item.

# Tutorial: Search Available Product Type Definitions

# Step 2. Retrieve Schema Documents

In the previous step, the retrieved Amazon product type definition includes details about the Amazon product type and links to retrieve the meta schema and product type schema documents. The links provided are valid for 7 days.

Schema documents can be retrieved programmatically with a standard HTTP client or manually with a web browser.

Important Note: The Amazon product type definition JSON Schema document references the meta schema by name. Some JSON Schema libraries attempt to resolve meta schema names online via the web, which the Amazon Product Type Definition Meta-Schema (v1) (opens new window) does not support. These libraries should be configured to use a downloaded copy of the meta schema instead. See the accompanying Amazon Product Type Definition Meta-Schema (v1) (opens new window) documentation for more details.

# Frequently Asked Questions

This documentation covers common questions and details for the Product Type Definitions API. For questions or concerns not covered by this documentation, contact Selling Partner API support or create an issue on the GitHub repository.

# How Fresh are Amazon Product Type Definitions?

Unless specifying a previous productTypeVersion, the Amazon product type definitions always describe the latest up-to-date Amazon catalog requirements.

# Are All Amazon Product Types Available with the Product Type Definitions API?

No.

Amazon is continually expanding support for new and existing Amazon product types in the Product Type Definitions API. For the up-to-date list of available Amazon product types, use the Product Type Definitions API.

# What Version of JSON Schema is Used?

Amazon product type definition JSON Schemas extend JSON Schema 2019-09 (opens new window). See the accompanying Amazon Product Type Definition Meta-Schema (v1) (opens new window) documentation for more details.

# How Will Future Versions of JSON Schema be Leveraged?

As future versions of JSON Schema are adopted by the Product Type Definitions API, they will be accompanied by a new version release of the Product Type Definitions API and Amazon Product Type Definition Meta-Schema (opens new window).

Future versions of JSON Schema will not be adopted by existing versions of the Product Type Definitions API or Amazon Product Type Definition Meta-Schema (opens new window).

# Do Product Type Definition JSON Schemas Include Custom Vocabulary?

Most Amazon catalog requirements are described utilizing standard JSON Schema 2019-09 (opens new window) vocabulary. However, there are a few requirements that necessitate extending JSON Schema with custom vocabulary. See the accompanying Amazon Product Type Definition Meta-Schema (v1) (opens new window) documentation for more details.

# Am I Required to Implement Validation for Custom Vocabulary?

No.

The Amazon Product Type Definition Meta-Schema (v1) (opens new window) uses custom vocabulary to fully describe Amazon catalog requirements. Validating data with custom data enables you to prevent most listings-related issues from occurring before submitting to Amazon. However, it is up-to-you to implement such validation. Without implementing this validation, submitting data to Amazon may produce listings-related issues after submission to Amazon.

# Do I Need Custom Code to Use JSON Schemas?

Yes.

The amount of custom code depends upon your application. Example scenarios:

  • Using Open-Source Library with Validation of Custom Vocabulary: Leveraging an open-source library to handle most JSON Schema validation means custom code is necessary to retrieve schemas from the Product Type Definitions API, to implement validation of custom vocabulary, and to integrate with the open-source library.

  • Using Open-Source Library without Validation of Custom Vocabulary: Leveraging an open-source library to handle most JSON Schema validation means custom code is necessary to retrieve schemas from the Product Type Definitions API and to integrate with the open-source library.

# What Open-Source Libraries are Available?

Dozens of open-source libraries and implementations are available to validate data, render user interfaces, and generate code. See JSON Schema Implementations (opens new window) for a full list.

Amazon does not directly support or endorse any specific open-source or commercial libraries and implementations. Examples provided in this documentation are for reference only.

# What Examples are Available for Validating Data with Product Type Schemas?

The accompanying Amazon Product Type Definition Meta-Schema (v1) (opens new window) documentation includes example integrations with open-source libraries to validate data with custom vocabulary in .NET (C#), Java, and JavaScript (Node.js).

# How Do I Report Issues with Amazon Product Type Definitions?

For issues specific to the Product Type Definitions API or the content of Amazon product type definition JSON Schemas, contact Selling Partner API support (opens new window).
