About TutuPay
TutuPay is the unified payment, balance and billing hub for the Tutu suite. One Tutu account = one shared balance: top up once (Alipay / WeChat or a redeem code) and pay for value-added services in any product (tutuedit, tutucut, tutuaudio…) from the same balance. Products no longer build their own payments.
Why your money is safe
Row-lock
Balance changes run in a single transaction with row locks — concurrent debits can never drive the balance negative.
Signature-verified
Payment callbacks are MD5-verified and amount-checked before marking paid — forged callbacks are rejected.
Idempotent
Mark-paid, redeem and refund are atomic and idempotent — repeats never double-charge or double-spend.
Self-healing
A scheduler reconciles on a timer: retries unfulfilled paid orders, backfills lost callbacks, and recovers automatically on restart.
A few things to know
- Card details never pass through us: payments are handled by official Alipay / WeChat; we only keep the trade numbers needed for reconciliation.
- Every balance change has a before/after ledger snapshot — reconcile and trace any entry anytime.
- Top-up balance is for suite use only and non-withdrawable (see Terms).
