Overseas App API Integration & API Delivery Services — Tools / Payments / Tickets / Currency Apps

Our Capabilities

We are a technology services team focused on App interface integration and authorized API integration, with many years of experience in mobile apps and fintech. We specialize in delivering deployable API source code, OpenAPI documentation, Postman collections, and automated test scripts for overseas tools, payments, and ticketing apps through compliant authorizations, protocol analysis, and Open Data integration.

Compliance Note: We operate only with explicit client authorization or based on official/public APIs (Open Data / Authorized APIs). We strictly comply with applicable laws and privacy protections, and NDA can be signed when necessary.

Core Service Highlights

• Cross-platform support: Android / iOS client integrations and backend examples (Node.js / Python / Java)
• Standardized deliverables: OpenAPI/Swagger docs, Postman collections, and sample code
• Authentication & Security: OAuth2, JWT, HTTPS/TLS, two-factor and biometric integration guidance
• Open Data & Third-party integrations: access to exchange rates, ticketing, lotteries, and AEPS data sources
• Extensibility: caching strategies, rate limiting, retry mechanisms, and anomaly alerting

Frequently Asked Questions

What if I only provide the App name, what can you do?

You simply provide the target App name and requirements (e.g., need for transaction details, exchange rates, ticketing or payment interfaces); we will perform protocol analysis and Open Data/third-party API integration within the authorized scope and deliver runnable implementations and documentation.

How do you handle private interfaces that aren\'t publicly accessible?

We prioritize official APIs / authorized channels and public data. If compatibility work is required for non-public protocols, we will confirm legal authorization with the client first and use compliant reverse engineering or Open Data alternatives with a compliance assessment.

What is the typical delivery timeline?

Timeline depends on complexity; common tool/transform interfaces take 3–7 business days, while payments/banking/ticketing with compliance integration take 7–15 business days.
