The details below provide information on the item submission service level agreement (SLA) and potential exceptions.

What is the item submission service level agreement (SLA)?
A bulk item submission (create or update) takes up to four hours to process.
Are there any exceptions to the SLA?
Walmart fulfilled submissions that require Hazmat checks can go into a manual Walmart associate review process. This review process is noted in the feed status response. The SLA for this review can take up to 48 hours.
How long does it take for items to be visible in Walmart’s catalog or on Walmart.com?
There is an SLA of up to six hours between when an item is successfully submitted and when the data is available.
How can I tell if my item submission was successful?
Item submissions (setup or maintenance) are assigned a feed status. Sellers can locate and monitor their submission status by using the Feed Status API, or sellers can view their Walmart’s catalog item status using the read request APIs (POST Catalog Search, Get All Items, or Get An Item).
