IMPORTANT – Please keep in mind that the fulfillment lag time set above 1 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 will set it above one day without permission your quantity feeds will be rejected by Walmart API. You can request 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: Orders or Shipping -> Lag Time -> Making a lag time request:
Shipping Standards for Walmart Marketplace Sellers
