Currency exchange rates

If currency exchange is required, then the currency parameter should be filled for both request body objects – from and to, which are used in Preflight, Fees, and Payments methods.

If the currency parameter is filled only in one of the objects, or currency values are the same, then the currency exchange will not take place.

If currency exchange is not carried out, then the quote and rate response body parameters will have null value.

If the currency exchange is requested, the exchangeFee response body object of Preflight, Fees, and Payments methods will include currency exchange fee details.

The currencies exchange rates update every 5 minutes. All types of a transfer use the current exchange rate. For example:

1. An API integrator has checked the currency exchange rate using the Preflight or Fees method at 01:01 pm, decided to continue the transfer, then created and confirmed your first operation at 1:03 pm. The operation will proceed with the expected currency exchange rate.
2. Next, the integrator decided to create and confirm a second operation with the same currencies and transfer amount at 1:07 pm.
3. The currency exchange rate differed from the one in the first operation at 1:03 pm, so the value of the transaction is not the same. This happened because operations were confirmed in different operational periods (first operation – 1:00-1:05 pm; second operation – 1.05-1:10 pm).

We recommend checking and confirming transfers within the currencies exchange rates update period.
The Preflight and Fees methods return the quote parameter in the response body, which can be used in Payments request body to prolong the currency exchange rate for the operation.

The transfer fee is not included and not shown in the initial transfer amount. It is paid by the sender in addition to the transfer amount.

A fee is debited from the sender’s AlterId when each transfer is completed. The fee amount depends on the payment system via which the recipient will receive the payment.
