IMPORTANT – Please keep in mind that the fulfillment lag time set above one day has to be approved by Walmart support. 1 day of lag means a seller has about 48 business hours to ship the order. If you set it above one day without permission, your lag time feeds will be rejected by Walmart API. You can request an extended fulfillment lag time on your Walmart Seller Center by submitting a support case.
The category path you need to follow to submit a request: Items & Inventory > Request exemption > Lag time exemption request:
