REST & GraphQL APIs, payment gateways, CRM/ERP connectivity, secure auth, and real-time data sync — we build the integration layer that makes your entire technology ecosystem work as one.
From REST and GraphQL APIs to payment gateways, CRM/ERP connectivity, and real-time data sync — we build every layer of your integration stack.
Production-grade APIs built to industry standards — RESTful endpoints, GraphQL schemas, versioning, rate limiting, pagination, and comprehensive documentation that developers love.
Connect your platform to any third-party service — communication tools, cloud storage, analytics platforms, marketing tools, and more — with reliable, monitored, and fault-tolerant connectors.
Secure, PCI-compliant payment integrations with Stripe, Razorpay, PayPal, and regional gateways — including subscriptions, refunds, webhooks, and multi-currency support.
Bi-directional integration between your applications and enterprise systems — Salesforce, HubSpot, SAP, Oracle, and custom ERPs — with data mapping, transformation, and conflict resolution.
Enterprise-grade API security — OAuth2, JWT, API key management, rate limiting, IP whitelisting, and granular permission scopes — protecting every endpoint from day one.
WebSocket connections, webhook infrastructure, event-driven architecture, and message queues — keeping your data consistent and up-to-date across every system in real time.
Intellihub sits at the centre of your technology ecosystem — connecting every platform, tool, and data source through a single, secure, high-performance integration layer.

We map every system, data flow, and integration requirement — existing APIs, third-party services, authentication needs, and performance expectations — before designing anything.
The reasons engineering teams across India, USA, and Australia trust Intellihub to build and maintain their integration layer.
Every API we build is documented from the first endpoint — OpenAPI specs, Postman collections, and developer guides that make integration fast for your team and your clients.
From OAuth2 and JWT to rate limiting, IP whitelisting, and encryption in transit — every endpoint is secured before it goes live, never as an afterthought.
Sub-50ms response times, efficient caching strategies, database query optimisation, and load-tested infrastructure — APIs that perform whether you have 100 or 1 million requests.
We don't just build and hand over. We monitor uptime, track error rates, manage versioning, and evolve your APIs as your product and integrations grow.
