Create label
The Create label API lets you buy labels from Walmart to ship orders.
Endpoint
POST https://marketplace.walmartapis.com/v3/shipping/labelsFunction
Use this API to:
- Create domestic shipment labels with optional add-on features such as:
- Shipment protection: When Shipment Protection is enabled, Walmart will provide a replacement or refund if a shipment is lost, damaged, or stolen during transit.
- Signature protection: Requires the recipient to sign they received the order upon delivery. This feature provides an added layer of security and proof of delivery.
- Create international order shipment labels.
- Get tracking numbers, carrier services, or tracking URLs in the response.
- (US marketplace only) Create a label with your carrier account. A seller must onboard with the Walmart seller center UI to use their own account when buying a shipping label from a partner.
