Freeze rate for Operations with Exchange
This endpoint is used to freeze the exchange rate for a certain time in order to perform the subsequent exchange of one asset for another.
Freeze rate includes the cost of transactions, which are components of the exchange operation (deposit, exchange, withdrawal), so it may change for different types of operations.
For example, for a crypto-crypto exchange operation (target and source assets are already in the client's account), the exchange rate will be more favorable than for a deposit with exchange operation (the client buys crypto for fiat).
The payment method selected for operation can also have an additional influence on the exchange rate.
In order to determine which assets are being exchanged, it is enough to specify the source- and target-asset, where the source asset is the currency being exchanged and the target asset is the currency for which the exchange is taking place. In addition, it is necessary to indicate the source amount (the amount that the client is ready to spend as a source asset) or the target amount (the amount that the client wants to receive).
For the correct calculation of the freeze rate, it is necessary to specify the operation type for which the freezing is carried out.
Deposit and withdrawal payment methods witch available for operation types can be obtained using a pre-request of operations.
The default freeze rate time is 30 seconds. This value can be changed for different types of currencies.
