If you use the Sponsored Products feature for advertising your products on Walmart, there is good news for you. Recently Walmart implemented integration that will allow you to manage your Sponsored Products ads through Walmart Seller Center. After activating it, the Ad Center should appear on the upper bar of your Walmart Seller Center right beside the WFS icon. This will undoubtedly make ads management more manageable and less time-consuming.
If you are not advertising on Walmart yet and would like to start, you can contact the Walmart Connect team through this form.
