Transactions eligible for settlement are automatically settled every 24 hours. The action required depends on the transaction status you wish to void.

If the Transaction Has Already Been Settled

If the transaction you wish to void has already been settled, it cannot be voided. Instead, you need to issue a refund transaction to return funds to the customer's card or bank account. For instructions on issuing a refund transaction see: How to issue a refund transaction?

If the Transaction is Pending Settlement

If the transaction you wish to void has been approved and is pending settlement, it can be voided.

Authorization Retention on Voided Transactions

When a transaction is voided, the authorization might still persist. The preauthorized amount, which is reserved against the customer's credit card limit, will remain for a specific period until the card-issuer expires it. This duration varies among all card-issuing banks, and you will need to contact them directly to determine their hold times.

Even if the customer hasn't made a purchase with their credit card, future transactions may be declined because the credit limit has been reached. It's important for merchants to know that normal transaction fees apply for all resubmitted transactions.

Authorize.net does not have the ability to remove existing authorizations held on the customer's credit card. However, you can contact the card-issuing bank with your merchant number and the authorization code to request the removal of held funds. The authorization code can be retrieved by viewing the details associated with the transaction.
