Notifications: What You Should Know

Note the following about Notifications:

• The process and APIs used to subscribe to and manage notifications are the same for all events at Walmart.
• The webhook and event notification payload that Walmart sends will be unique for each event that Walmart sends.
  • Note: For specified events where different outcomes are possible, the notification payload may vary by event outcome.
• Subscribe to events with different authentication frameworks. Walmart can send notifications through Basic, HMAC, and OAuth.
• When an event occurs, Walmart expects to receive a 200 response back from the supplier’s request. If the supplier service does not return a 200 response, Walmart will retry sending the event two more times (equaling three times total).
• Events are not meant to replace API integration flows. Continue to use read requests to get all details, as events are meant to be lightweight and only maintain minimal information.

Walmart is working to build out the events available for subscription. If there are additional events that would increase supplier efficiency in working with Walmart, let your Walmart points of contact know.
