Cart API

What's new: Cart API is now available

Supported regions: NA, EU

The Amazon Business Cart API is now available. This API allows you to manage Amazon Business shopping carts programmatically by listing and retrieving cart details, adding, modifying, and removing items from carts, and estimating the total purchase cost of a cart before purchase, including tax and shipping charges. You can use this API along with Product Search API and Ordering API to design a full end-to-end purchasing experience in your application. For more information about this API, see Cart API overview .

This API provides the following operations:

Product Search API

What's new: sortKey

Supported regions: NA, EU, FE

The Product Search API searchProductsRequest operation now supports the sortKey query parameter, allowing you to control the order in which search results are returned. Use this parameter to sort products by relevance, price, popularity, customer ratings, and other criteria to better match your business needs.

📘

If the sortKey parameter is not provided or contains an invalid value, the API defaults to sorting by RELEVANCE.

The API response returns the applied sortKey value, allowing you to confirm which sort order was applied to the search. 

GET https://na.business-api.amazon.com/products/2020-08-26/products?keywords=laptop&pageNumber=0&locale=en_US&productRegion=US&inclusionsForProducts:ALL,isBundledAsin&sortKey=PRICE_LOW_TO_HIGH&facets=OFFERS

{
  "numberOfPages": 13,
  "products": [ 
    "..."
],
  "legalInformation": [],
  "sortKey": "PRICE_LOW_TO_HIGH"
 }

What's new: minPrice and maxPrice filters

Supported regions: NA, EU, FE

The Product Search API searchProductsRequest operation now supports filtering search results by price range using two new optional query parameters:

  • minPrice: Minimum price used to filter search results. When specified, only products with prices greater than or equal to this value are returned.
  • maxPrice: Maximum price used to filter search results. When specified, only products with prices less than or equal to this value are returned.

📘

Both parameters represent prices in the marketplace's default currency without decimal points. For example, to filter products between $10.00 and $50.00 in the US marketplace, you would use minPrice=10 and maxPrice=50.

The API response now includes these parameters in the API response, showing which price filters were applied to the search.

GET https://na.business-api.amazon.com/products/2020-08-26/products?keywords=laptop&pageNumber=0&locale=en_US&productRegion=US&minPrice=50&maxPrice=100&inclusionsForProducts:ALL,isBundledAsin&facets=OFFERS
