What types of APIs does Walmart offer?

Walmart offers read-and-write representational state transfer (REST) synchronous APIs to suppliers across various functions. In addition, Walmart supports various bulk functions for suppliers through asynchronous API flows.

Walmart bulk asynchronous APIs

Walmart supports both POST and READ APIs for bulk functionality.

• POST: Walmart leverages feeds to handle all bulk write cases. A feed consists of an HTTP request with an attached file. For more about feeds, reference the Feeds guide.
• READ Bulk: Walmart uses reports to handle all bulk-read use cases. A supplier can request a report, and Walmart will return an API response with a compressed comma-separated value (CSV) file as an attachment. For more about reports, refer to the Reports guide.
