Connect every system, automate every workflow. We design and build rock-solid RESTful and GraphQL APIs that power apps, integrate platforms, and eliminate manual data entry — permanently.
Every modern business runs on APIs — they're the invisible glue between your CRM, ERP, payment gateway, mobile app, and web platform. Our API specialists have built and integrated 300+ APIs across every major platform, delivering the connected, automated business you deserve.
Salesforce ↔ SAP, Shopify ↔ Tally, Zoho ↔ WhatsApp — we integrate any combination of platforms with rock-solid, error-tolerant API bridges.
Real-time bidirectional sync means data entered in one system instantly appears in all others. No more copy-paste, no more human error, no more delays.
OAuth 2.0, JWT, API key management, rate limiting, IP whitelisting, and end-to-end encryption — APIs your security team will sign off on.
Every API we build comes with interactive Swagger documentation, Postman collections, and developer guides — enabling your team to build on top of it.
Horizontal scaling, caching (Redis), async processing (message queues), and load balancing ensure your APIs perform flawlessly under any load.
Push data the instant events happen — no polling, no delays. WebSocket, Server-Sent Events, and webhook architectures for true real-time systems.
A transparent, results-driven process — from your brief to a live, revenue-generating solution.
No hidden fees. Choose the plan that fits your business, or let us build a custom quote.
Every feature, every plan — side by side, so you can choose with complete confidence.

Everything you need to know before making your decision.
REST is simpler and widely understood — ideal for most business integrations. GraphQL gives clients precise control over data fetching — perfect for complex products where bandwidth efficiency matters. We'll recommend the right approach based on your use case.
Yes. We build middleware adapters that read directly from databases (MySQL, MSSQL, Oracle), FTP servers, CSV exports, or legacy file formats — then expose them as modern REST APIs. Your modern frontend gets clean data regardless of how old the backend is.
We implement defence-in-depth: OAuth 2.0/JWT for authentication, HTTPS enforcement, input sanitisation, parameterised queries (SQL injection prevention), rate limiting, CORS policies, IP whitelisting, and API key rotation. Every API undergoes security testing before delivery.
Yes, always. Every API we build includes interactive Swagger / OpenAPI documentation, a Postman collection, and a developer guide. These are kept up-to-date with every API version change.
Yes, absolutely. We have deep experience with Tally ERP integration (using Tally XML API), Busy Accounting, and other Indian ERP systems. We extract inventory, invoices, and customer data in real-time to sync with your website or mobile app.
