API & Integrations

Connect everything.
Break nothing. |

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.

Six integration capabilities.
One connected ecosystem.

From REST and GraphQL APIs to payment gateways, CRM/ERP connectivity, and real-time data sync — we build every layer of your integration stack.

REST & GraphQL API Development

Production-grade APIs built to industry standards — RESTful endpoints, GraphQL schemas, versioning, rate limiting, pagination, and comprehensive documentation that developers love.

REST
GraphQL
OpenAPI
Swagger

Third-Party Service Integrations

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.

Twilio
SendGrid
AWS S3
Zapier

Payment Gateway Integrations

Secure, PCI-compliant payment integrations with Stripe, Razorpay, PayPal, and regional gateways — including subscriptions, refunds, webhooks, and multi-currency support.

CRM & ERP Connectivity

Bi-directional integration between your applications and enterprise systems — Salesforce, HubSpot, SAP, Oracle, and custom ERPs — with data mapping, transformation, and conflict resolution.

Secure Auth & Authorization

Enterprise-grade API security — OAuth2, JWT, API key management, rate limiting, IP whitelisting, and granular permission scopes — protecting every endpoint from day one.

Real-Time Data Synchronization

WebSocket connections, webhook infrastructure, event-driven architecture, and message queues — keeping your data consistent and up-to-date across every system in real time.

Load testing, security scans & QA

6. Documentation & launch

Developer docs, monitoring & support

API discovery & scoping

We map every system, data flow, and integration requirement — existing APIs, third-party services, authentication needs, and performance expectations — before designing anything.

  • System & data flow mapping
  • Integration requirements gathering
  • Authentication & security scoping
  • Performance & scalability benchmarks

APIs that are built to
last and scale.

The reasons engineering teams across India, USA, and Australia trust Intellihub to build and maintain their integration layer.

 

Documentation-first approach

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.

Security at every layer

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.

Performance that holds under load

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.

Maintained and monitored

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.
