The developer is testing APIs.

Kolkata's trading, distribution, and manufacturing businesses often run several systems that don't talk to each other — an ERP here, a billing tool there, a partner portal somewhere else. APIs are what tie them together and let data move without manual re-entry. Boldally builds and integrates APIs for Kolkata companies remotely on the same IST clock, with clear documentation, sensible security, and weekly progress. We come on-site for kickoffs or major milestones when a project needs them. Whether it's a new API for your app or connecting to a payment or logistics provider, we keep it clean and well-documented.

Built for how Kolkata businesses actually run

Kolkata is a trading and manufacturing city with a deep base in distribution, jute, leather, engineering, and a growing services and IT sector around Salt Lake. Most off-the-shelf software ignores how these businesses actually keep their books and move their stock.

  • Trading & distribution houses

    Order, stock, and ledger systems that match how Burrabazar and wholesale firms work, with GST billing and party-wise outstanding built in.

  • Manufacturers (jute, leather, engineering)

    Software that ties production, raw material, and dispatch into one record so the office and the floor see the same numbers.

  • Services & finance firms

    CRMs, client portals, and dashboards that replace scattered spreadsheets and email follow-ups.

  • IT & startups in Salt Lake / Sector V

    Product MVPs, internal tools, and APIs for teams building software in the city's tech belt.

Our API Development Services Services

Custom API Development

We build APIs around your data and the systems that need to read or write it, so the integrations stop being one-off scripts.

API Management & Optimization

We tune existing APIs for speed and reliability, and add the rate limits, caching, and monitoring they were missing.

Third-Party API Integrations

We connect your app to outside services like payment, shipping, or CRM APIs and handle the auth, errors, and retries that come with them.

Our Process

Our API Development Process

Typical Timeline: 2-6 weeks depending on API complexity and integration requirements

01

Requirements & Planning

We map which systems need to talk, what data moves between them, and how it should be secured. From that we define the endpoints, auth, and schemas, with room to add more later.

02

Design & Documentation

We write the API spec in OpenAPI/Swagger and design the REST or GraphQL endpoints with consistent naming and a versioning plan, so other teams can build against them without guessing.

03

Development & Testing

Using Laravel, Node.js, or Express.js, we build the APIs and back them with automated tests, load tests, and security scans, so they don't buckle under a traffic spike or leak data.

04

Deployment & Monitoring

We deploy to production with rate limiting, caching, and monitoring in place. You get full documentation and SDK examples, and we keep watching performance so problems surface before your users hit them.

Why a same-timezone India team works for Kolkata businesses

  • Same hours, same-day answers

    We work in IST, so a question in the morning gets an answer the same day, not overnight from a foreign agency.

  • We know Indian trade and GST

    Party ledgers, outstanding, batch and lot tracking, and GST billing are things we already build, not things we learn on your project.

  • Weekly progress, code you keep

    A clear scope, working software you can see every week, and clean source code with documentation. You're never locked in.
