Processing fee
When your customer fulfills a payment request and you receive the funds, a processing fee will be subtracted from your account. The fee is the same as a deposit fee for the same amount.
Just like for a deposit, the fee may depend on the currency and on whether the payment involved a conversion between different currencies. Each fee is calculated as a percentage of the deposit amount, but for small transactions, a certain minimum amount will be subtracted instead.
The fees are listed on the Fees tab in your portal, under the Deposit operations section. The applicable fees are:
- Deposit crypto
- Deposit crypto exchange to crypto
- Deposit crypto exchange to fiat
Passing the processing fee to your customer
By default, the processing fee is covered by the merchant. If you prefer, you can pass this fee on to your customer. In this case, after selecting the payment currency, the customer will be shown the corresponding processing fee and expected to pay it on top of the requested amount. CryptoProcessing will account for the fee when detecting overpayments or applying the underpayment tolerance.
To enable this, check the Customer pays the processing fee checkbox when creating a payment request via the portal or use the user_fee_percent parameter when creating it via the API.
Note that this setting does not affect the currency_received.amount field in the payment callback. If you allow underpayments and perform actions based on the exact received amount (e.g., update your customer’s balance), you need to subtract the processing fee yourself.
Refund fee
If an automatic or manual refund is initiated, a fixed refund fee will be subtracted from its amount. The customer will be shown both the fee amount and the result amount they receive when they fill in the refund form. The fee may depend on the currency in which the refund will be sent, which is the same currency the customer paid.
If the refund itself is smaller than the fee, the customer will not be able to receive it.Last modified on October 15, 2026
