Print WFS Inbound Carrier Label
POST/api/walmart/:integrationInstance/wfs/inbound-shipments/:shipment/carrier-label
Print the carrier label for a booked WFS inbound shipment. The response is the raw label document itself — binary PDF bytes streamed as a file download (Content-Type: application/pdf, Content-Disposition: attachment), NOT a JSON envelope. Scoped to the integration instance (404 if the shipment belongs to another instance).
Any valid API token can call this endpoint — no specific scope required. Manage tokens.
Request body:
- ship_date (optional, nullable, date) — the ship date to stamp on the label; defaults to today (UTC) when omitted.
Responses:
- 200: the PDF label bytes (binary download).
- 404: the shipment does not belong to the given integration instance.
- 422: ship_date is not a valid date.
Requires a Bearer token.

Response Headers
Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.
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.
Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.
Unprocessable Entity
Response Headers
Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
