Final-Authorisation
Final-authorisation is the default and most commonly used transaction type.
The authorised amount must be captured exactly as it was initiated.
It is not allowed to void (cancel) the transaction, unless the transaction is suspected to be fraudulent.
In such cases, the void must be performed within 72 hours.
You can set the capture delay for up to 3 days.
Pre-Authorisation
Pre-authorisation is used less frequently, but it is necessary in scenarios where the final transaction amount may vary (e.g., hotel bookings, car rentals).
You can finalise the transaction for a smaller amount than originally authorised.
You can void the authorisation if needed.
The capture delay can be set for up to 7 days.
Use final-authorisation for straightforward payments where the amount is fixed. Choose pre-authorisation if the final amount might change or if you need flexibility to cancel the transaction later.
