Cloud, data and integration
API development and system integration
Make your systems talk to each other. We build secure APIs and connect payment gateways, ERPs, CRMs, WhatsApp and government services.
What is API integration?
API integration connects separate software systems through their application programming interfaces so data moves between them automatically, for example sending orders from a website to an ERP, payments to accounting, or leads to a CRM.
What our api development and integration covers
REST and GraphQL APIs plus integrations with payment, ERP, CRM and government systems.
REST and GraphQL
Well documented, versioned APIs.
Payment gateways
Razorpay, PayU, Cashfree and Stripe.
ERP and accounting
Tally, SAP, Zoho and Busy.
Messaging
WhatsApp, SMS and email providers.
Government APIs
GST, e-invoice and DigiLocker through providers.
Monitoring
Retries, logs and alerts.
How we approach api development and integration
Double entry between systems wastes time and creates errors. Integration removes it.
We document every API and add monitoring so failures are noticed.
Every project starts with a short discovery call and ends with software you own: source code, data, cloud accounts and documentation are handed over in your name.
Modules and features
Built for
Technology we use
From first call to launch
The same five stages for every build, with a working demo at the end of each sprint so you see progress, not promises.
Discovery
We map your process, users and data, agree the first release and give you a fixed price for it.
Design
Clickable prototypes of the key screens, reviewed with the people who will use them every day.
Build in sprints
Two week sprints with a demo each time. You can change priorities between sprints.
Test and launch
Functional, security and load testing, data migration, training and a planned go live.
Support and grow
Monitoring, fixes and new features on a monthly plan, or a clean handover to your team.

Learn moreQuestions about api development and integration
Can you connect our website to Tally?
Yes, orders and invoices can sync automatically.
Do you write API documentation?
Yes, using OpenAPI with examples.
What if a third party API is down?
We queue and retry requests and alert your team.
Do you work only in Kolkata?
Our engineering team is based in New Town, Kolkata, and we work with clients across West Bengal, the rest of India and overseas. Most projects run remotely with weekly demos, and we meet in person when it helps.

Share three details. A senior engineer from our Kolkata team will call you, understand the problem and send a written scope with timeline and cost. No obligation, no spam.
- A short call with an engineer, not a salesperson
- A written scope: modules, technology, timeline and fixed cost for phase one
- Honest advice, including when an existing product fits better than custom code
