Transaction Types

Sale (`sale`)

A sale transaction is submitted for immediate authorization and settlement.

Authorization (`auth`)

An auth transaction is authorized immediately but not flagged for settlement. To settle an authorized transaction, use the capture transaction type.

Capture (`capture`)

A capture transaction flags a previously authorized transaction for settlement.

Only auth transactions can be captured.
The capture amount must be equal to or less than the original authorization amount.

Void (`void`)

A void transaction cancels a previously submitted sale or captured auth.

Non-captured auth transactions can also be voided to prevent future capture.
Voids are only valid before the transaction has been settled.

Refund (`refund`)

A refund reverses a previously settled transaction or one pending settlement.

If the transaction has not been settled, use a void instead.

Credit (`credit`)

A credit applies funds directly to the cardholder's account without referencing a prior transaction.

Note: Credits are typically disabled. Use refund transactions instead when reversing a prior charge.

Validate (`validate`)

A validate transaction verifies the cardholder’s account without authorizing or settling any funds.
This is used for card/account verification only.
