一次又一次申請退款的客戶並非偶然。退款濫用不僅讓你退回金額，還要搭上你已經花掉的算力，而兩大商店都會給你一個身分訊號，即 Apple 的 appAccountToken 和 Google 的混淆帳戶 ID，用來把這種模式串連起來。
Apple 和 Google 都可能核准退款,但顧客手上的購買項目卻原封不動。這篇文章會精確說明什麼情況下系統會自動撤銷存取權限,什麼情況下要靠你的伺服器自己處理,以及那個幾乎所有整合都會漏接的通知。
Only two refund flows ever ask for your evidence: Apple's consumption request and Google Play's chargeback review. Everything else, the 48-hour Play refund, support refunds, voided purchases, unacknowledged trials, is decided without you. Here is the full map, what you can prevent, and what you can only record.
