A "Void" operation refers to the cancellation of a transaction before it is fully processed or settled. It typically occurs after the authorization stage (when the funds are reserved) but before the funds are actually transferred. Voiding a payment prevents the money from leaving the customer's account or being deposited into the merchant's account.

Here are key points about a Void operation:

Timing: It must happen before the payment is settled (i.e., before the transaction is completed).

Result: The funds are not moved; the payment is effectively erased as if it never happened.

No Refund Needed: Since the funds were never actually transferred, there's no need for a refund, which would be necessary if the payment had been fully processed.

In summary, a Void cancels the pending transaction without affecting the customer’s account balance because no money was transferred yet.
