Availability: Note that this invoice integration is no longer available in Sweden. If you are a Swedish merchant and wish to offer invoice as a payment option, this has to be done through our payment order implementation.

Introduction

  • When properly set up in your merchant/webshop site and the payer starts the purchase process, you need to make a POST request towards Swedbank Pay with your Purchase information. This will generate a payment object with a unique paymentID. You will receive a redirect URL to a Swedbank Pay payment page.
  • You need to redirect the payer’s browser to that specified URL so that the payer can enter the invoice details in a secure Swedbank Pay environment.
  • Swedbank Pay will redirect the payer’s browser to - one of two specified URLs, depending on whether the payment session is followed through completely or cancelled beforehand. Please note that both a successful and rejected payment reach completion, in contrast to a cancelled payment.
  • When you detect that the payer reach your completeUrl , you need to do a GET request to receive the state of the transaction, containing the paymentID generated in the first step, to receive the state of the transaction.

Step 1: Create The Payment

  • An invoice payment is always two-phased based - you create an Authorize transaction, that is followed by a Capture or Cancel request.

Callback URL: It is mandatory to set a callbackUrl in the POST request creating the payment. When callbackUrl is set, Swedbank Pay will send a POST request to this URL when the payer has fulfilled the payment. Upon receiving this POST request, a subsequent GET request towards the id of the payment generated initially must be made to receive the state of the transaction.

warning

GDPR: GDPR sensitive data such as email, phone numbers and social security numbers must not be used directly in request fields such as payerReference. If it is necessary to use GDPR sensitive data, it must be hashed and then the hash can be used in requests towards Swedbank Pay.

To initiate the payment process, you need to make a POST request to Swedbank Pay. Our payment example below uses the [FinancingConsumer] (/old-implementations/payment-instruments-v1/invoice/features/technical-reference/financing-consumer) value. All valid options when posting a payment with operation equal to FinancingConsumer, are described in features.

check completeUrl string The URL that Swedbank Pay will redirect back to when the payer has completed their interactions with the payment. This does not indicate a successful payment, only that it has reached a final (complete) state. A GET request needs to be performed on the payment to inspect it further. See completeUrl for details.
  cancelUrl string The URL to redirect the payer to if the payment is cancelled. Only used in redirect scenarios. Can not be used simultaneously with paymentUrl; only cancelUrl or paymentUrl can be used, not both.
  paymentUrl string The paymentUrl represents the URL that Swedbank Pay will redirect back to when the view-operation needs to be loaded, to inspect and act on the current status of the payment, such as when the payer is redirected out of the Seamless View (the <iframe>) and sent back after completing the payment. paymentUrl is only used in Seamless Views and should point to the page of where the Payment Order Seamless View is hosted.

  subsite string(40) The subsite field can be used to perform a split settlement on the payment. The different subsite values must be resolved with Swedbank Pay reconciliation before being used.
