Invoice

Redirect

schedule 7 min read

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 a 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 value. All valid options when posting a payment with operation equal to FinancingConsumer, are described in other features.
