Amounts and Fees
Top-ups, product orders and OpenAPI collections may include fees. Before paying, review the transaction amount, fee, and total payable separately.
Top-up fees
Total payable = top-up amount + fee
The fee is normally added to the top-up amount and is not deducted from the expected TDC credit shown on the page. For example:
| Item | Amount or note |
|---|---|
| Top-up amount | 10.00 USD |
| Fee | 4.56 USD |
| Total payable | 14.56 USD |
| Expected credit | As shown on the confirmation page |
Product order fees
The payment confirmation page lists:
- the product subtotal;
- the buyer fee;
- the final payable amount;
- the payment currency.
If the product price and payment channel use different currencies, the confirmation page shows the converted payable amount. Use the final amount displayed there.
Merchant proceeds
For platform-channel collection, buyer fees increase the payer total and merchant fees reduce settlement proceeds. Net proceeds are credited in TDC; buyer fees are excluded from merchant income. Merchant-owned channels receive funds directly, without a second TDC sales credit.
Amounts and fees are rounded in the selected payment currency. A positive fee has a minimum equal to the methodβs smallest chargeable amount. The displayed payer total is used for the provider charge. Currencies without a supported amount format are not offered.
Refunds and duplicate notifications
Full refunds are verified against the original payer total. TDC accounting uses the saved exchange rate. Fees are nonrefundable, so refunds can exceed net proceeds; guarantee and other funds cover the difference under platform rules. Partial refunds are not automatically processed as full-order refunds.
Only verified payment confirms a credit. Returning to a page or clicking a success button is not evidence of payment. Duplicate notifications do not credit twice, and replaying the original payment notification after a refund does not settle the order again.
Historical amounts
Top-up history and order details retain the amount and currency confirmed for the transaction. If a payment result has not updated or an amount looks incorrect, do not pay again; contact platform support with the order number.
