Swish E-Commerce
Enable consumers to either enter their mobile number or scan a QR code using the Swish app on their mobile device, subsequently authorising the payment by following the instructions in the Swish app.
Swish supports two types of e-commerce payment journeys:
QR code : Display a QR code for the consumer to scan using their Swish app.
Phone Number : The consumer enters their phone number to start the payment process.
To support these journeys, PPRO offers following integration options :
PPRO-hosted
Consumers are redirected to a PPRO managed payment page, where they can either scan the QR code or follow the provided instructions to complete the payment.
Merchant checkout
Consumers are redirected to a merchant managed payment page, where they can either scan the QR code or follow the provided instructions to complete the payment.
Note
As part of the onboarding process, you will be required to specify whether you prefer a PPRO hosted or merchant checkout integration.
More details on QR code and Phone number journeys are provided below.
QR Code
There are two main methods to generate the QR code, as outlined below:
- PPRO-rendered : PPRO's QR code generation simplifies the process by providing either a base64 encoded string for decoding or a ready to display QR image.
- Customer rendered through QR Payload : QR Payload to generate QR image , swish design specifications to be followed while generation.
Swish Design Specification for QR Payload Method
The QR code should be created in black and white. The Swish symbol is placed in the centre, on a white circular background. The symbol width should be 25% of the QR code width.
The Swish symbol can be downloaded from the Swish marketing toolbox and should follow the Swish trademark guidelines.
We strongly recommend using the PPRO rendered QR code generation, as it simplifies the process by removing the need to follow Swish design specifications on your end.
For reference, PPRO rendered QR code generation is demonstrated below, providing both a ready to display QR image and a Base64 encoded string.
Note
For PPRO hosted payment integration, only ready-to-display QR images and QR payloads are supported. However, for merchant checkout integration, all QR code generation methods are supported.
