​
How it works

The Swish pay-in flow provides the following checkout experience:
1

User chooses payment method

On your app or website, the user selects Swish as the payment method
2

Payment initiation

You create the payment request by calling POST Create a Swish PayIn, specifying the ReturnURL.If the ReturnURL redirects to your app, rather than a website, you need to also set the PaymentFlow to APP.
3

Redirection

On a website, you redirect the user via the RedirectURL response value to a hosted payment page containing the QR code. Alternatively, you can integrate a PNG of the QR code into your payment page using the QRCodeURL value (which is Base64-encoded).In an app-to-app flow, you redirect the user to their Swish app via the DeepLinkURL response value.After pressing the pay button, the user uses the Swedish Mobile BankID system to validate the payment.
Note – Timeout after 3 minutesThe payment session lasts for 3 minutes, at which point the pay-in fails automatically if no action has been taken by the user.
4

Return

After payment, the user is returned on your specified ReturnURL:
  • To a website if PaymentFlow is WEB (default value)
  • To a mobile app if the PaymentFlow is APP
5

Outcome

The transaction is complete when the pay-in status changes from CREATED to SUCCEEDED or FAILED, indicating the outcome.
