Lists all transactions for an account. Sorted by last updated at.

List transactions

Attempts to create an authorization for a payment method. In some cases it is
not possible to create the authorization without redirecting the user for
their authorization. In these cases the status is set to
indicate buyer approval is pending and an approval URL is returned.

Duplicated gift card numbers are not supported. This includes both stored gift
cards, as well as those directly provided via the request.


New transaction

Get transaction

Captures a previously authorized transaction.

Capture transaction

Voids a transaction.

If the transaction was not yet successfully authorized, or was already
captured, the void will not be processed. Captured transactions can be
refunded instead.

Voiding zero-amount authorized transactions is not supported.

Once voided, the status of the transaction will be either `authorization_voided`,
`authorization_void_pending`, or if the void fails the original status will remain.

Void transaction

Get a list of events related to processing a transaction.

List events for transaction

Sync the transaction with the payment service to get the latest status,
amounts, and some of the identifiers. This is only available for some payment
service providers.

Sync transaction

List buyers

to this buyer.


New buyer
