SDK makes it simple – the Art of Integration.

We're excited to share that NextApps has completed the world's first integration of PayU's mobile payment SDK with Flutter technology. We can't wait to show you how we did it.


Integrating different technologies, systems, or platforms often involves linking things that may not naturally work together. These differences can be due to the way they're built, how they handle data, how they communicate, or how they keep information secure. This makes the job of bringing them together tricky, as developers must figure out how to make these different pieces fit together. Without any standard rules or connections to follow, each integration needs its own special development. This means the communication and data sharing between systems has to be specially designed each time. This lack of a standard way of doing things can make the job more difficult and time-consuming, as developers have to create and put into action specific integration points and mappings. Security is another big challenge. Developers must make sure that data privacy is maintained, only the right people have access, and that communication is secure. This adds another layer of difficulty to integration work. They have to use appropriate security measures and protocols to ensure the safety of the integrated systems and data.


Software Development Kits (SDKs) often include ready-made components, libraries, and APIs that make it easier to work with a specific platform or system. These ready-made parts give developers a standard and simpler way to connect their applications with the system they're targeting. SDKs offer tools and resources specially created for integrating with a specific system, which means developers don't have to build everything from the ground up. This lets developers concentrate on the main purpose of their applications, instead of getting bogged down with the details of integration. Using an SDK can make the development process up to 10 times faster.

The cooperation with NextApps - PayU has been excellent. Starting from the pilot presentation of the SDK concept in Flutter technology, demonstration of the PayU demo application, through a series of discussions on the implementation of module integration, to the final form of the H-Our Store product. Effectively, professionally.


While you can integrate without an SDK, it usually results in a more complex and time-consuming process. SDKs offer a streamlined, standard way to integration, which simplifies the development process, guarantees compatibility, and provides extra resources and support. By combining Flutter's tools and PayU's mobile SDK, you can create a mobile application that enables easy payments via credit card, online bank transfer, BLIK, and digital wallets like Google Pay and Apple Pay. Using an SDK ensures the app's security, reduces the development time, and keeps the application updated and maintained.
