​
What is One-time Payment?

One-time Payment refers to a payment model where a fee is charged for a single, standalone transaction. In this model, every payment is independent, involving no recurring charges or automatic renewals. Due to its clear structure and direct process, it is the most fundamental and common form of payment, applicable to a wide range of business scenarios.

Frequently asked questions

Does One-time Payment support refunds?

Yes (subject to the specific payment method’s capabilities). Most mainstream payment methods support refunds. However, whether full or partial refunds are supported strictly depends on the rules and capabilities of the underlying payment method.
All transaction data is synced in real-time to the Waffo Dashboard. It supports filtering by time, amount, and status, as well as exporting reports in CSV format.
Waffo returns specific failure reason codes (e.g., “Insufficient Funds,” “Declined by Issuer”). We recommend that merchants prompt users on the front end to switch payment methods and retry.
