Publishing API の呼び出しを開始するには、Google Play Console から直接 API プロジェクトにリンクし、そのプロジェクトで Publishing API を有効にする必要があります。セットアップした API プロジェクトは、ご自分の他のゲーム プロジェクトの管理にも使用できます。
Publishing API にアクセスするには、Google Play Console を API プロジェクトにリンクする必要があります。通常は新しい API プロジェクトを作成するようおすすめしますが、現在 Google Play Developer Publishing API をご利用であれば、既存の API プロジェクトにリンクすることができます。なお、各 API プロジェクトは Google Play Console の 1 つのアカウントにのみリンク可能であることにご注意ください。
