Trustly – Seamless View

The Seamless View scenario represents the opportunity to implement Trustly directly in your webshop.

Introduction

Seamless View provides an integration of the payment process directly on your website. This solution offers a smooth shopping experience with Swedbank Pay Payments 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 website.

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

A Trustly payment is a straightforward way to perform a direct-bank payment.

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 Payment resource.

When properly set up in your merchant/webshop site and the payer starts the payment process, you need to make a POST request towards Swedbank Pay with your payment information. This will generate a payment resource with a unique id URL. You will receive a JavaScript source in response.

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.

`intent`	`string`	`Sale` is the only intent option for Trustly. Performs the payment when the end-user gets redirected and completes the payment.
`currency`	`string`	`SEK`, `EUR`. The currency of the provided `amount`.

}

The key information in the response is the view-sale 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 the href value obtained in the POST request in the <script> element. Example:

1

    <script id="payment-page-script" src="https://ecom.externalintegration.payex.com/trustly/core/ scripts/client/px.trustly.client.js"></script>

The previous two steps gives this HTML:

        </div>

Load The Seamless View

Lastly, initiate the Seamless View with a JavaScript call to open the iframe embedded on your website.
