Case Study: Building the Citcon Developer Portal

About the Client

Citcon is a global leader in cross-border mobile payment solutions, enabling merchants to accept international wallets like Alipay, WeChat Pay, UnionPay, and over 100 other mobile payment methods. Trusted by Fortune 500 retailers and enterprise merchants, Citcon serves as the connective tissue between Western merchants and consumers in Asia, LATAM, and other rapidly digitizing markets.

To scale their platform and attract developers, integrators, and ISVs, Citcon recognized the need to modernize and centralize its developer experience—creating a best-in-class Developer Portal that reflects its product maturity, enables rapid integration, and builds trust through clear, secure, and up-to-date technical resources.

The Challenge

Despite having robust APIs powering payment acceptance and transaction management, Citcon’s documentation and developer onboarding experience were fragmented across internal tools and outdated PDF guides. This made it harder for developers to:

Internally, product and engineering teams lacked a centralized way to manage changelogs, versioning, code samples, and security notices.

Citcon needed a modern Developer Portal to:

  • Support self-serve onboarding for third-party devs and merchant integrators

  • House API docs, SDKs, webhooks, changelogs, and quickstart guides

  • Comply with SOC 2 and PCI security requirements

  • Scale globally with support for international dev teams

  • Reflect the speed, reliability, and elegance of the Citcon platform

The Solution

Pungo designed and built a scalable, user-friendly Developer Portal from the ground up—focused on clarity, ease of use, and long-term maintainability. Our engagement included:

🔧 Architecture & Platform

  • Chose Docusaurus (React-based) as the documentation framework for its extensibility, theming, and developer familiarity

  • Integrated with GitHub CI/CD workflows so engineers could update docs with each API release

  • Set up a custom plugin for versioning, allowing developers to reference current and deprecated API versions seamlessly

📖 Documentation & Content Strategy

  • Consolidated and rewrote all existing docs for consistency, tone, and technical accuracy

  • Created Quickstart guides for key flows: Payment Integration, Refund API, and Webhooks

  • Designed code examples in multiple languages: Node.js, Python, Java, and PHP

  • Added a Changelog system with RSS + web notifications

  • Developed a structured FAQ, API glossary, and error code reference

🔒 Security & Access

  • Added role-based login controls for sandbox vs production access

  • Embedded links to SOC 2 and PCI documentation and endpoint security specifications

  • Created an automated token generation demo and security walkthrough page

🌍 Globalization

  • Designed layout and content structure for multi-language support and future translation into Mandarin and Spanish

  • Followed WCAG accessibility guidelines and ensured responsive design for desktop and mobile devs

💡 Developer Experience

  • Embedded an interactive API explorer using Swagger/OpenAPI

  • Added “Copy Code” buttons, syntax highlighting, dark mode, and personalized onboarding checklists

  • Designed a portal homepage that contextualized each product offering, allowing devs to jump into SDKs, test APIs, or view sample dashboards instantly

Results

After the launch of the Developer Portal, Citcon reported:

  • 70% decrease in time-to-integrate for new partners and developers

  • Significant reduction in support tickets for onboarding and authentication questions

  • Improved API adoption across third-party logistics and POS vendors

  • Internal engineering teams now contribute to docs autonomously via GitHub PRs

  • Enhanced trust from partners during audits and enterprise onboarding

The portal now functions not only as a technical resource, but as a strategic business asset—shortening sales cycles, reducing developer friction, and reinforcing Citcon’s reputation as a modern, secure global payments platform.
