Yuno Wins Best Payment API at the API Awards 2025

Yuno has just won the award for Best Payment API at the API Awards 2025. But what few people see behind this achievement is the complete strategy that made such a robust API also accessible, clear, and scalable.

Behind this recognition lies deep documentation work, in addition to the entire infrastructure development. And it was with great pride that WriteChoice took part in this journey, helping turn complexity into clarity and creating an experience that guides the developer from the first access to final integration.

Three years of building and a continuous purpose: clarity, scale, and well-defined workflows

The project with Yuno started from scratch. At the beginning, it took us just two months to release a docs MVP. However, over the last three years we have been maintaining this portal while Yuno was scaling the product, our team had laser focus onl clear user journeys, agile integration, and accessibility. 

Yuno Docs was designed to map not only endpoints and SDK functions, but also the usage flows a developer must follow to succeed.

In the world of payment APIs, there are many possible paths, but there are also mandatory sequences for everything to work. Many companies fail to document these workflows end to end. In Yuno’s case, each flow was mapped and explained, allowing developers to know exactly what to do and in what order.

More than writing, we architected a developer experience. Each page was created with real testing, a focus on usability, and alignment with the product’s strategic vision.

Today, this portal is considered one of the most inspiring in the FinTech space and is a central part of Yuno’s growth engine.

Your API may be amazing, but without good documentation, it does not sell

Many companies invest millions in API development but neglect documentation. The problem? Without good instructions, the adoption curve grows as much as the support ticket queue.

That is where WriteChoice’s technical documentation team comes in. We extract and organize everything from the most basic to the most advanced information, ensuring that any developer, even without prior experience, can understand and implement with confidence.

In Yuno’s case, clarity was treated as a competitive advantage from day one, and it made all the difference. The documentation was not just a byproduct. It was built as a commercial asset from the very first day. This is what we do best at WriteChoice: turning documentation into strategy and into a growth lever.

When API documentation is built as a product, results follow

WriteChoice goes beyond technical writing. We are an all-in-one solution delivering design, development, UX, QA, and a documentation platform, all aligned with the business vision. This approach allows us to deliver documentation that drives real impact: reducing support tickets, accelerating onboarding, and generating more revenue.

For Yuno, we also designed the experience so that in 15 to 20 minutes, the developer reaches their first “A-HA moment”:

• In 5 minutes, create an account and configure a payment connection on the dashboard.

• In 10 minutes, an experienced dev can create a payment with their SDK.

The bottom line is that in under 15 minutes, they can create a payment and understand the meat of how Yuno works.

These quick wins generate trust and motivation for the developer to explore the product further. Yuno’s recognition at the API Awards is proof of that.

We are building the benchmark in API documentation

Cases like Yuno’s show we are on the right path. WriteChoice has been consolidating its position as the reference company in the API and software documentation market.

Our edge lies in translating ambition into clarity. We deliver in weeks what used to take months, with an international standard and a strategic approach to every line we write. We believe the future belongs to companies that treat documentation as part of the product, and we are ready to lead that transformation.

Congratulations, Yuno,  and thank you for trusting us.

Yuno believed in the importance of documentation from the start. Seeing this API shine on the global stage is a reminder: great ideas need great instructions to go far.
