Fulfill Order

POST 
/api/3pl/orders/fulfillmentOrder/fulfill

Report a shipment for a fulfillment order — the partner confirms what it shipped. Creates one SalesOrderFulfillment against the FO (inventory + COGS post at ship-time), decrements each line's remaining, and advances the FO Open → Incomplete ("Partially shipped") → Closed.

Body:

• lines (required, min 1): {id, quantity_fulfilled} where id is the FULFILLMENT ORDER LINE id (from List Orders), quantity_fulfilled numeric ≥ 0 (clamped to remaining).
• fulfilled_at (required date): the actual shipped timestamp (drives COGS dating).
• shipping_method, tracking_number (optional).
• provider_shipment_id (optional): idempotent dedup — a retried fulfill never records a duplicate shipment.

All-zero report → 422.

Auth: 3PL Integration Token (Bearer).

Successful response

401

Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.

403

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.

422

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.

429

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.
