    "store": "myStore-US",
    "asn_nr": "<asn_nr>"
  }
}

  -H "Content-Type: application/json" \
  -d '{"store":"myStore-US","asn_nr":"<asn_nr>"}'
```

## Arguments

| Name | Type | Required | Description |
|---|---|---|---|
| `store` | string | yes | the noon account ref `<account>-<CC>` (name-country, e.g. 'myNoon-AE') — one of get_user_context's noon store_refs, verbatim. |
| `asn_nr` | string | yes | the noon ASN number (from noon_inbound_ListShipments). Right after noon_inbound_CreateShipment it is data.shipment.asn_nr. |
| `items` | object[] |  | the lines (required) — partner_sku, qty (units) and storage_type: the full value (e.g. STORAGE_TYPE_STANDARD), sent verbatim — copy it from noon_inbound_ListEligibleItems. |

## Result

- `data.shipment` — the refreshed ASN header (as noon_inbound_GetShipment) — expected_qty and total_sku_count reflect the upsert; noon returns no per-item status.

## Body (noon schema)

- asn_nr*: string items*: [{partner_sku*, qty*, storage_type*}] items.storage_type: STORAGE_TYPE_UNSPECIFIED | STORAGE_TYPE_STANDARD | STORAGE_TYPE_OVERSIZE | STORAGE_TYPE_BULKY
