Swish M-Commerce
Allow consumers to pay via Swish by redirecting them from a merchant's website or mobile app to the Swish app. They should authorise the payment and then be redirected back to the merchant's website or mobile app.
Integration Methods
There are two integration methods for the m-commerce journey: direct and indirect redirection. Each option has its own benefits, and the choice should depend on your specific needs and available resources.
Direct redirection
This approach enables direct navigation between merchant app or merchant website on a mobile device and the Swish app, providing a seamless and native user experience.
Indirect redirection
This method redirects users from the merchant app or merchant website on a mobile device to the Swish app and then back to the merchant app or website, with a brief transition through the browser.
Summarised view is as follows:
| Dimension | Direct redirection | Indirect redirection |
|---|---|---|
| Suitable for | Large business | Small to medium sized business |
| User Experience | Superior and seamless | Not Smooth |
| Consumer Experience | Excellent | Good |
| Development effort | Significant | Minimal |
| Transaction Status update | Polled by Merchant | Published by PPRO |
Our Recommendation
While both methods have their advantages, we recommend the direct redirection approach for merchants with the resources to implement it. This method offers a superior user experience, which can result in higher conversion rates and increased consumer satisfaction. However, if you are a small to medium-sized merchant seeking a quicker implementation with minimal development effort on your end, indirect redirection is a suitable choice.
Ultimately, the decision should be based on your specific business needs and development capabilities.
Consumer Entry Points
For the M-Commerce journey, the consumer's payment experience can begin either through the merchant's mobile app or website on their mobile device. Once initiated, the next step involves seamlessly routing the consumer to the Swish app to authorise and complete the payment.
The following section outlines the process for both of these starting points, ensuring a smooth and efficient payment flow for your customers.
Kickstarting from the Merchant App
In the direct redirection from the merchant app to the Swish app, the consumer is redirected directly to the Swish app to complete the payment and is then returned to the merchant app once the payment is authorised
Consumer Journey
- The consumer selects Swish as their preferred payment method on merchant app.
- The consumer is routed to Swish app where they are required to enter the desired details, authorise and complete the transaction.
- The consumer is routed back to merchant app on mobile device directly after completing the transaction
- The merchant receives the payment confirmation
- The merchant ships the order/deliver the goods to the consumer.
In the indirect redirection from the merchant app to the Swish app, the consumer is redirected to the Swish app to complete the payment and then returned to the merchant app via the browser once the payment is authorised
- The consumer selects Swish as their preferred payment method on merchant app.
- The consumer is routed to Swish app where they are required to enter the desired details, authorise and complete the transaction.
- The consumer is routed back to merchant app via browser after completing the transaction
- The merchant receives the payment confirmation
- The merchant ships the order/deliver the goods to the consumer.
