We have activated new payment functionalities on Czech Republic APIs – future dated CZK domestic instant payments (will allow create new CZK domestic IPs with future date and also allows specific timeslot using "requestedExecutionTime") that allows creation and processing even during weekends and holidays.
For UniCredit Bank SK, this feature for SEPA IPs and STOs is available since March 2026.
Sandbox CZ/SK implementation already includes both these features.
