API Development & Integration Services

Our API development and integration services cover the complete lifecycle: requirements analysis, API architecture design, custom development (REST, GraphQL, gRPC), third-party integration, security testing, documentation, deployment, and post-launch support. We deliver APIs for enterprises, startups, and government organisations under CMMI Level 5 quality processes and ISO 27001 security standards.

REST APIs use multiple endpoints with fixed data structures, are simple, widely supported, and ideal for most integrations. GraphQL uses a single endpoint where clients request exactly the data they need, reducing over-fetching best for complex data relationships. SOAP is an XML-based protocol suited to legacy enterprise systems requiring formal contracts and strict compliance. We recommend the right approach based on your integration requirements.

Development timelines depend on complexity and scope. Simple REST APIs with 5–10 endpoints typically take 4–8 weeks from discovery to production. Complex enterprise integrations with microservices architecture, compliance requirements, and multiple third-party connections generally take 3–6 months. We use agile methodology to deliver working endpoints incrementally, allowing early testing throughout the build.

We implement multi-layered API security at every stage: OAuth 2.0 and JWT authentication, SSL/TLS encryption at rest and in transit, rate limiting, input validation, and full OWASP Top 10 compliance. Our QA team conducts penetration testing and security audits before every production release. For healthcare clients, we build to HIPAA standards; for government, we follow CERT-In guidelines.

Yes. We specialise in India Stack integrations, including Aadhaar eKYC, DigiLocker document verification, UPI payment rails, GSTN compliance APIs, and e-Sign services. Our team follows UIDAI guidelines, NPCI protocols, and CERT-In security standards. We have delivered live government API integrations for the Bureau of Energy Efficiency and the Parliament of India in production environments.

Yes. We build HIPAA-compliant healthcare APIs with HL7 FHIR-based data exchange, end-to-end encryption, role-based access control, and detailed audit logging at every data access point. We also support ABDM Health ID integration and FDA 21 CFR Part 11 compliant electronic records systems for healthcare clients operating in India and internationally.

An API gateway is a centralised entry point that manages all incoming API traffic, handling authentication, rate limiting, request routing, load balancing, and analytics in one layer. If you are exposing APIs to multiple consumers, running microservices, or need centralised security enforcement, an API gateway is strongly recommended. We implement Kong, AWS API Gateway, and Azure API Management depending on your stack.
