Amazon Data Feed

Do you support Amazon Marketplace Seller Central data feeds?

We support Amazon Marketplace Price & Inventory Feeds and Inventory Loader feeds. Read on for more information about how to use these feeds.

Overview of Amazon Marketplace

The Sell on Amazon program allows you to sell your items directly on Amazon's main website. Your company will be listed as a third-party seller on product pages. Shoppers checkout on Amazon's site, and you pay Amazon a commission on the sale.

List Products Already on

Price & Inventory and Inventory Loader feeds are exclusively for listing products that already exist on Amazon.

As such, this feed does not require any product details, only the quantity in stock, product identifier (UPC), and your selling price.

To get started, please read our article, Amazon Inventory Loader and Price and Quantity Update Feeds, or contact us for a quote.

List Products not yet on

Category-specific, Inventory Template Feeds are used to add items to that do not already exist there.

Each top-level product category on Amazon has different data feed requirements, which are spelled out in their Inventory templates for product categories.

You can use the Amazon Product Classifier to determine the appropriate Inventory template for your products.

Amazon has strict requirements for adding new items. You will likely need to do item-by-item content work on your product catalog. At a bare minimum, Amazon requires that you specify a UPC code, product type, and item type for each item. Additional requirements vary by category. Unfortunately, we do not offer content-editing services to add your products to Amazon Marketplace.

If you already have a working and tested spreadsheet that you upload to Amazon, we can program your rules into our system and set the feed up to run automatically. Please contact us for a quote.

Amazon Inventory Loader and Price and Quantity Update Feeds

We are able to generate and submit Amazon Inventory Loader or Amazon Price and Quantity Update feeds to Amazon.


  • Uploads your price, quantity, and UPC code only
  • Feed submit automatically every day (or more frequently if desired)
  • Our system maintains your SKUs in order to zero out the quantity if you delete, remove, or discontinue an item from your store
  • We custom-program your business rules (pricing, filtering, etc.)
  • We can provide settings for markup rules, filters, etc. that you can modify via our website anytime
  • Feed is uploaded automatically to your Amazon account via our integration with Amazon MWS (Merchant Web Services API)
  • We do not need your Amazon account login (you just grant us the limited access to MWS that we need)

Requirements and Limitations

  • UPC codes (or EAN/ISBN/ASIN) are mandatory
  • Only items that already exist in the Amazon Marketplace will be listed
  • Items that do not exist in Amazon will error out and be ignored
  • You are responsible for obtaining necessary approvals from Amazon for the items and categories you want to sell

Note that in some cases, a UPC code may match up to two different products in Amazon. Amazon provides some tools to help you select specific listings.


Please contact us for a pricing quote, which would involve a monthly fee and a setup fee.

The setup fee includes the following:

  • setting up a price/quantity/UPC feed for your store
  • obtaining access to your Amazon account via MWS
  • setting up the persistent SKU table
  • programming in your business/pricing rules/filtering rules
  • doing test submissions to Amazon
  • revising until such time that the feed is working as desired
  • scheduling the feed according to the desired frequency.
