Build/Update Fulfillment Packet
POST/api/walmart/:integrationInstance/wfs/inbound-shipments/:shipment/fulfillment
Build (or refresh) the fulfilment packet for a 3PL/supplier-sourced inbound — resolves the source type, scaffolds the staged document set, and mints a portal token. Re-calling updates the existing packet (channels, build flag, instruction override) and re-scaffolds documents. Returns 422 if the shipment is direct-warehouse sourced (no packet applies) or its source is unresolved.
Any valid API token can call this endpoint — no specific scope required. Manage tokens.
Authentication: Requires Bearer token.
Fields:
- channels (string[], optional, each one of email|portal): delivery channels. portal is always included even if omitted.
- build_kits (boolean, optional, default false): when true AND the shipment has component-sourced kits, adds a Kitting Work Order and marks build_required.
- instruction_override (string, optional, nullable, max 5000): replaces the auto-generated prep instructions.

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.
Validation failed — the body is a field → messages map (Laravel shape) or the platform envelope with a stable machine-readable code. Fix the payload and resubmit.
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.
