/*
Notes:
- This "Automated Step" will cancel the fine-tune job by FtJob ID.
    - Example of FtJob ID: "ft-AF1WoRqd3aJAHsqc9NY7iL8F"
    - Fine-Tuned jobs cannot be canceled.
        - `"Cannot cancel a job ft-lN1WPLOp8rtoalbMG5Nctc0T that already has status \"succeeded\"."`
- If you place this "Automated Step" in the Workflow diagram, the request will be automatically sent every time the process token arrives.
    - A request is automatically sent to the OpenAI API server. (REST API)
    - The response from the OpenAI API server is automatically parsed.

APPENDIX
- To activate a Workflow App that includes this Automated Step, "HTTP Authz Setting" is required
    - Obtain a "Secret API Key" in advance.
    - Set the key as the communication token in "Token Fixed Value"


Notes-ja:
- この［自動工程］は、FtJob IDでファインチューンJob（微調整ジョブ）をキャンセルします。
    - Example of FtJob ID: "ft-AF1WoRqd3aJAHsqc9NY7iL8F"
    - Fine Tune 完了済みジョブはキャンセルできません。
        - `"Cannot cancel a job ft-lN1WPLOp8rtoalbMG5Nctc0T that already has status \"succeeded\"."`
- この［自動工程］をワークフロー図に配置すれば、案件が到達する度にリクエストが自動送信されます。
    - OpenAI API サーバに対してリクエストが自動送出されます。（REST API通信）
    - OpenAI API サーバからのレスポンスが自動保存解析されます。

APPENDIX-ja
- この［アドオン自動工程］を含むワークフローアプリを運用するには［HTTP 認証設定］が必要です。
    - あらかじめ "Secret API Key" を取得しておいてください。
    - "Secret API Key" を通信トークンとしてセットします。［トークン直接指定］
