Connected systems, less manual work
Modern software platforms rely on Application Programming Interfaces (APIs) to communicate seamlessly with external SaaS services, mobile applications, third-party partners and internal microservices. Poorly designed APIs result in data synchronization failures, security vulnerabilities, unhandled rate limits and slow overall system performance. Netbii engineers robust RESTful and GraphQL APIs that serve as secure, high-performance integration layers for your business software assets.
We work with web platforms, mobile apps, custom database systems and enterprise software products to build custom APIs and integrate third-party commercial tools into your operational workflows.
Our integration solutions ensure your data flows automatically between legacy software systems, cloud applications and mobile clients without requiring manual entry or brittle file exports.
APIs designed to last
We engineer APIs following strict industry architectural standards, ensuring long-term maintainability, backward compatibility, clear error handling and high server availability under heavy traffic loads:
- RESTful API engineering building clear, standardized HTTP interfaces with predictable URL resource structures, standard status codes and structured JSON error responses.
- GraphQL API development allowing mobile and frontend web clients to request exact data fields, reducing network payload size and eliminating multiple round-trip requests.
- Authentication and authorization implementing OAuth 2.0, JWT token validation, API key management and granular role-based access scope permissions.
- Webhook and event-driven architecture processing real-time event notifications with asynchronous background queue workers and automated retry logic.
- Comprehensive API documentation generating interactive OpenAPI (Swagger) specifications and Postman collections for internal and external developer onboarding.
Integrations we build
We connect custom software platforms with major third-party SaaS products, cloud tools and financial infrastructure. We handle complex authentication flows, rate-limiting constraints, data transformation and error recovery across external service providers:
We build custom integrations for payment gateways (Stripe, PayPal, Square), CRM platforms (Salesforce, HubSpot), accounting software (Xero, QuickBooks), ERP platforms (SAP, NetSuite) and communications services (Twilio, SendGrid, Slack, WhatsApp Business API).
Whether you are exposing public endpoints for ecosystem developers or syncing data across internal business departments, we structure your integration architecture to handle network failures gracefully.
Security, reliability and monitoring
API security is paramount, as public endpoints represent primary targets for automated attacks. We protect API infrastructure with request throttling, IP rate limiting, strict CORS origin policies, input sanitization and token revocation mechanisms. We also implement real-time monitoring to track API response times, error rates and payload performance continuously.
We also implement request signature validation, HMAC authentication tokens, and audit logging layers to protect your backend APIs against replay attacks, data tampering, and malicious request injection attempts across all public endpoints.
API lifecycle management and versioning
As business requirements shift, APIs must evolve without breaking existing web apps or mobile clients. We use semantic versioning, documented deprecation policies and automated integration test suites. Together with an API gateway, response caching and clear rules for breaking changes, this lets your API evolve while existing apps keep working.
Our engineering team also implements response caching headers, Redis-backed rate limiting gates, and fallback queue buffers so your frontend applications stay fast and responsive even when third-party partner services experience temporary downtime or network degradation.
