準備

Php/GooglePlayApi [ｼｮｰﾄｶｯﾄ]

上記ページの以下処理を行う。

  1. gcpでサービスアカウントを作成し鍵を作る
  2. Google Play Android Developer APIを有効に
  3. PlayConsoleにサービスアカウントの権限を追加して、売上を見れるように。

GooglePlayAPIのvoided-purchasesを使用

このAPIは、自サーバからdevelopers.googleのAPIへ、問い合わせして、返金情報をリストで取得するもの

https://developers.google.com/android-publisher/voided-purchases?hl=ja

https://developers.google.com/android-publisher/api-ref/rest/v3/purchases.voidedpurchases/list?hl=ja

https://developers.google.com/android-publisher/api-ref/rest/v3/purchases.voidedpurchases?hl=ja#VoidedPurchase 

voidedSource：取り消し済みの購入の開始者。有効な値は 0 です。ユーザー 1.デベロッパー 2.Google
voidedReason：購入が取り消された理由。有効な値は 0 です。その他 1.購入者都合 2.Not_received 3.欠陥 4.Accidental_purchase 5.不正行為 6.フレンドリーな不正行為 7.チャージバック 8.Unacknowledged_purchase
