# Return Shipment の詳細を取得

<Warning>
  このページはAIによって自動翻訳されています。API技術仕様は英語が正式です。不明点がある場合は[英語版](/api-reference/returnshipment/get-return-request)を参照してください。
</Warning>

[Return Shipment を作成](/ja/api-reference/returnshipment/create-return-shipment) から返される `returnRequestId` を使って、単一の**返品シップメント**の完全なレコード（シップメント、明細、ラベル、カスタムフィールド）を取得します。

返品シップメントは**倉庫到着前**のパーセルを表します。倉庫がパーセルを登録すると*返品在庫*アイテムになります。その段階以降は、入荷後の処理データを持つ [取得 返品在庫 詳細](/ja/api-reference/returninventory/get-return-inventory-details) を使用してください。

<h2 id="recovering-a-missed-label">
  見逃したラベルの復旧
</h2>

ラベルは `shipments[].label.labelUrl` にあります。このエンドポイントの主な用途は**システム障害後の突合**です。受信側がラベル通知を見逃した場合、`returnRequestId` で呼び出して現在の `labelUrl` と `trackingNumber` を直接読み取れます。`labelUrl` が空の場合は生成が未完了（または失敗）であることを意味します——`shipments[].label.labelRequestStatusCode` を確認してください。

<Warning>
  これは予備の手段であり、主たる手段ではありません。ラベルは非同期で生成され、`labelGenerated` webhook で配信されます。それが真実のソースです。通常運用でラベルを知るために本エンドポイントをポーリングしないでください——[Webhooks](/ja/webhooks#label-result) を購読し、通知の見逃しや配信失敗後の補完にのみ本エンドポイントを使用してください。
</Warning>
