Context and Introduction

With the rapid growth in the popularity of mobile applications and the need to provide users with convenient and secure payment options, our client – a payment service provider – required a modern solution to enhance the integration capabilities of their payment gateway with mobile applications.

The previous approach, relying solely on WebView integration, limited the user experience and discouraged business clients due to performance issues and restricted UX capabilities. Our team's goal was to create a comprehensive SDK set that would provide a native payment experience within mobile applications while supporting the most popular frameworks – Flutter and React Native.

Problem Description

The main limitation of the client's previous solution was that payments could only be integrated via WebView, resulting in a poorer user experience, lower transaction conversion rates, and a higher cart abandonment rate. Limited integration capabilities with native applications further restricted the client's growth potential, making it difficult to attract large business partners who required a native implementation of payment solutions.

Proposed Solution

We developed a comprehensive SDK set consisting of native libraries for Android and iOS, as well as dedicated plugins for Flutter and React Native. Each SDK features a consistent API, allowing developers to quickly and seamlessly implement native mobile payments in any application, regardless of its technology stack.

The new solution eliminates the need for WebView, ensuring better performance, smoother operation, and enhanced security by integrating directly at the native application level. As a result, the client's payment platform became more attractive to demanding business partners who value stability, efficiency, and full control over their application's UX.

Results and Benefits

The introduction of the mobile payment SDK set brought significant business and technological benefits to the client. The number of applications using the solution increased by 120% within the first six months of launching the native SDKs. The new solution also positively impacted end-user satisfaction, with the average transaction conversion rate rising by over 35% compared to the previous WebView-based solution.

Additionally, the time required for SDK integration into partner applications was reduced from approximately two weeks to just two business days. The client also noted a decrease in reported technical issues and user complaints – the number of service requests related to mobile payments dropped by 50%.

Summary

The project of creating a native SDK set and plugins for Flutter and React Native proved to be a crucial step in the client's business development. As a result, the payment provider significantly expanded their business collaboration opportunities while improving service quality and end-user satisfaction. The project demonstrated that investing in modern, flexible, and native technology solutions effectively enhances competitive advantage in the demanding fintech market.
