Cancel service
After obtaining a cancel NIT in the previous step, the merchant will be able to reverse the desired payment.
After a successful cancellation, the payment transaction will change its status to EST (reversed). Depending on the acquirer, it may be possible to do partial reversals, which means cancelling a smaller amount than what was paid. In this case, the payment transaction will keep the CON status.
