Walmart API Use-cases


Walmart Open API is designed to make it easy for partners to integrate with the Walmart site in a way that enhances the customer experience on their application. The program has improved over time to address diverse needs. Here are some interesting use-cases.

To enable quickly discovering trending products online, the API provides special feeds of items that are hot selling on site right now. Examples of these could be items on rollback, and bestsellers by category. We have also put together a dedicated collection of products that are trending on right now. It uses multiple signals like page views and item getting ordered in realtime, and has shown higher click-throughs and conversions.

In addition to realtime inventory and pricing lookup API, effort has been underway to provide more reliable and realtime Walmart catalog feeds. Current feeds are updated once every 24 hours. To get faster updates, we publish a delta feed every few hours that only contains the items modified since the last feed generation job. This saves the trouble of having to look up realtime information making it a faster end-customer experience. We are also coming out with an update to the feeds API that will incorporate these changes directly in the data feeds.

Lookup API has been designed keeping in mind the need for an affiliate to show the most important parts of the product page to the end customer, along with the availability and pricing status in realtime. This is why it has item descriptions, images and review information. The API now includes rich item information such as nutritional values for food products, and cast/release dates for digital content. We are piloting this with a few categories right now. Let us know what you think and how this could be improved further.

We constantly endeavor to provide you with the best and most relevant shopping information, powered by the Walmart Labs teams that have extensive experience in this area. Please reach out to us if you feel you have an interesting use-case that we could address. We would love to hear from you.
