Portal — Print WFS GTIN Item Labels (public)
POST/api/walmart/:integrationInstance/wfs/inbound-shipments/fulfillment-portal/:token/item-labels
Self-service GTIN item labels from the PUBLIC fulfillment portal — the 3PL/supplier prints the barcode label sheet (PDF) straight from the portal, no login. Mirrors the authenticated "Print WFS GTIN Item Labels (shipment)" download. Defaults to ONE LABEL PER UNIT of every shipment line when the body is empty; pass items to override per-SKU label counts (per-row printing).
Any valid API token can call this endpoint — no specific scope required. Manage tokens.
Walmart has no item-label API — SKU.io renders the GTIN/UPC barcode PDF locally, so the response is the raw PDF (application/pdf), not JSON. Each label encodes the product's GTIN, falling back to UPC, then the product barcode.
Request body (all optional):
- items (array, 1–500) — each: { sku (required string, max 255), quantity (required integer 1–3000) }.
- format: 'letter_30' (default) or 'thermal_2_25x1_25'.
Public, token-gated endpoint — NO bearer auth. The :token gates packet access; tenant is resolved by request host. 404 when the token is invalid/expired; 422 when the shipment has no lines or a SKU lacks a GTIN/UPC/barcode.

Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.
