This parameter controls the rate lock behavior.

standard - the customer will be able to choose the payment currency. The exchange rate will be locked after the customer confirms the selection on the first screen.

Available options:

standard,

If the amount the customer pays does not match the amount that you set for the payment request, CryptoProcessing will send an email to this address instructing the customer on how they can receive a refund.

Example:

"[email protected]"
