SHVA is an asynchronous provider and works in a unique way from other providers. All of the captured transactions sent during the day are collected and sent to shva for processing in one batch at night (GMT +2, considering day time savings). This process is called - "nightly batch". Note that the captured transaction status will be marked as "pending" on the dashboard until the batch is sent and the funds are captured.
Refund/void via shva
In order to cancel a SHVA transaction before the nightly capture batch is processed, a "void" request is required.
To cancel a SHVA transaction after the captured batch is processed, a "refund" request is required.
