Create label with multi-package

Market availability: CA, MX

The Create label with multi package API creates shipping labels for orders with multiple packages.

Endpoint

POST https://marketplace.walmartapis.com/v3/shipping/multi-package/labels

Function

Key features of this API include:

Multi-package shipping simplification: Create and manage shipping labels for orders with multiple packages to the same buyer. Sellers can define package-specific details, such as dimensions, weight, and contents, for each box.
Streamlined label creation: Generates shipping labels for each package in an order. This is useful for large or bulk orders that exceed the size or weight limitations for a single parcel.
Walmart's shipping discounts: Provides discounted rates with shipping carriers (such as FedEx, USPS, UPS) to reduce your shipping
Tracking and order management: Once the labels are created, the system generates unique tracking numbers for each package. These tracking details are automatically updated in Walmart’s Marketplace dashboard, providing both sellers and buyers with real-time shipment visibility.
Compliance and efficiency: Ensures your orders are aligned with Walmart's shipping and order fulfillment requirements, such as estimated delivery times and packaging standards.

Result

A successful response returns shipment label data in the data object. Key fields include:

purchaseOrderId: the purchase order associated with the shipment
trackingNo: the shipment tracking number
boxItems: the item list included in the shipment
carrierName and carrierFullName: the carrier used to create the label
carrierServiceType: the shipping service selected
trackingUrl: a link customers or operators can use to track the shipment
shippingDocuments: the label file encoded in base64
otherLabels: additional package labels created for the same purchase order

For MX responses, the label can return as ZPL and may include multiple labels under otherLabels. For CA responses, the label can return as PDF. If the request is invalid, the API can return a 400 error with field-level validation details or a 500 error for server-side issues.

Next Steps

The Create label API lets you buy labels from Walmart to ship orders.

The Shipping estimates API provides the cheapest rate to ship an order.

The Labels detail by purchase order ID API retrieves shipping label information for orders, label generation, formatting, and tracking information for shipping as well as order management.

The Supported carriers API gives you a list of approved Walmart carriers to ship orders.

The Download label API brings up the carrier label when searching by carrier and tracking number.

The Discard label API removes shipping labels.

The Supported carrier package types API provides the package types a carrier offers.

The Create scan form for labels API groups multiple labels so the carrier can scan a single document at pickup.

The Download scan form API downloads the scan form for a document.
