POST

/terminal/v1/sync/void

Cancels a transaction on the same business day, before the processor cutoff.
The amount is never debited from the cardholder's account.

Wait at least 1 minute after the original transaction before calling void.

🚧 Beta — Early Access
This API is in early access. Endpoints, parameters, and response structures
may change without prior notice. Do not deploy to production without
coordinating with the Kushki integration team.

Approximate cutoff in Mexico: 22:59 local time. Confirm the exact cutoff with your Kushki integration
team — once it passes, the transaction must be reversed with refund instead.
