Preauthorization is the temporary blocking of funds on the customer's payment card account.
From the customer's point of view, this is a regular card payment on payment gateway. When done, the amount is blocked, not deducted.
The maximum blocking period is 7 days. Blocking can be completed or cancelled based on the e-shop's instructions.
Pre-authorization can be finalized for the full amount or less than the original amount for payment.
Preauthorization can be used, for example, to book goods and services or when the final value of the transaction is not known in advance.
You can learn more about how to perform pre-authorization on the payment gateway in the API documentation.
