Payment Menu v2

After Payment

When the payer is done interacting with the Payment Menu, you need to implement the relevant after-payment operations in your order system. Which these operations are and how they are executed is described below.”

Operations

Most payment methods are two-phase payments – in which a successful payment order will result in an authorized transaction – that must be followed by a capture or cancellation transaction later on. One-phase payments like Swish are settled directly without the option to capture or cancel. For a full list of the available operations, see the technical reference.

Operation Description
create-paymentorder-capture The second part of a two-phase transaction where the authorized amount is sent from the payer to the payee. It is possible to do a part-capture on a subset of the authorized amount. Several captures on the same payment are possible, up to the total authorization amount.
create-paymentorder-cancel Used to cancel authorized and not yet captured transactions. If a cancellation is performed after doing a part-capture, it will only affect the not yet captured authorization amount.
create-paymentorder-reversal Used to reverse a payment. It is only possible to reverse a payment that has been captured and not yet reversed.

GET Request

To identify the operations that are available we need to do a GET request against the URL of paymentorder.id:

Cancel

Cancel

The cancellations resource lists the cancellation transactions on a specific payment.

Create Cancel Transaction

To cancel a previously created payment, you must perform the create-paymentorder-cancel operation against the accompanying href returned in the operations list. You can only cancel a payment - or part of a payment - which has not been captured yet. If you cancel before any capture has been done, no captures can be performed later.

payeeReference string(30) check

A unique reference from the merchant system. Set per operation to ensure an exactly-once delivery of a transactional operation.

If you handle the settlement, Swedbank Pay will send the payeeReference and it will be limited to the format of string(12). All characters must be digits.

Cancel Sequence Diagram

Cancel can only be done on an authorized transaction. As a cancellation does not have an amount associated with it, it will release the entire reserved amount. If your intention is to make detailed handling, such as only capturing a partial amount of the transaction, you must start with the capture of the desired amount before performing a cancel for the remaining reserved funds.

Reversal

If we want to reverse a previously captured amount, we need to perform create-paymentorder-reversal against the accompanying href returned in the operations list.
