Edit "After Payment" on GitHub

After the payment is confirmed, the payer will be redirected from the Swish app to the completeUrl set in the create payment request. You need to retrieve payment status with GET Sales transaction before presenting a confirmation page to the payer.

Options after posting a payment

  • If CallbackURL is set: Whenever changes to the payment occur a Callback request will be posted to the callbackUrl, which was generated when the payment was created.
  • You can create a reversal transactions by implementing the Reversal request. You can also access and reverse a payment through your merchant pages in the Swedbank Pay admin portal.

All Swish transactions are described below. Please note that Swish does not support Merchant Initiated Transactions for the time being.

Create Sales transaction

In browser based solutions the payers msisdn (mobile number) is required. This is managed either by sending a POST request as seen below, or by redirecting the payer to the hosted payment page. The msisdn is only required for browser based solutions. With mobile app based solutions, the payer uses the device that hosts the Swish app to manage the purchase, making msisdn optional.

}

The operation redirect-app-swish is only returned when using in-app flows.

The payment now contains a sale transaction with the status (state) AwaitingActivity, meaning we are awaiting a response from Swish. When the payer confirms the payment a callback request will follow from Swedbank Pay.

Reversals

The Reversals resource list the reversals transactions (one or more) on a specific payment.

Reversal Sequence

A reversal transcation need to match the Payee reference of a completed sales transaction.

Capture

Swish does not support capture as it is a one-phase payment method all completed payments are captured.

Cancel

Swish does not support cancel as cancel can only be used on two-phase payments before they are captured or reversed.

Recurring

Swish does not support recurring payments.
