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
Seamless View provides an integration of the payment process directly on your
website. This solution offers a smooth shopping experience with Swedbank Pay
payment pages seamlessly integrated in an iframe on your website. The payer
does not need to leave your webpage, since we are handling the payment in the
iframe on your page.
How It Looks

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.
Step 1: Create The Payment
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.
A FinancingConsumer payment is a straightforward way to invoice a
payer. It is followed up by posting a capture, cancellation or reversal
transaction.
An example of an abbreviated POST request is provided below. Each individual
field of the JSON document is described in the following section. An example of
an expanded POST request is available in the other features
section.
When properly set up in your merchant/webshop site and the payer starts the
invoice process, you need to make a POST request towards Swedbank Pay with your
invoice information. This will generate a payment object with a unique
paymentID. You will receive a JavaScript source in response.

}
 
 
The key information in the response is the view-authorization operation. You
will need to embed its href in a <script> element. The script will enable
loading the payment page in an iframe in our next step.
Please note that nested iframes (an iframe within an iframe) are unsupported.
Step 2: Display The Payment
You need to embed the script source on your site to create a Seamless View in an
iframe; so that the payer can enter the payment details in a secure Swedbank Pay
hosted environment. A simplified integration has these following steps:
- Create a container that will contain the Seamless View iframe: 
<div id="swedbank-pay-seamless-view-page">. - Create a 
<script>source within the container. Embed thehrefvalue obtained in thePOSTrequest in the<script>element. Example: 
1
 
    <script id="payment-page-script" src="https://ecom.externalintegration.payex.com/invoice/core/ scripts/client/px.invoice.client.js"></script>
 
 
The previous two steps gives this HTML:
