API & Business Integrations

Make your systems talk to each other.

We build APIs and connect the systems your business depends on — payments, messaging, authentication, third-party platforms, and internal tools — so information moves automatically instead of by hand.

Common questions

The connective tissue

Integration is where software either pays off or falls down.

Every system your business touches generates useful data, but it only pays off when that data moves reliably between systems. We design and build the APIs, connectors, and data flows that make your tools work as one — without fragile scripts that break in production.

When your tools don't talk to each other

Manual data transfer is the costliest software you already own.

01

Data has to be entered twice

Orders, customers, leads, and inventory sit in separate systems, so everything is retyped and nothing is consistent.

02

Business logic is repeated everywhere

Pricing, validation, and rules duplicated across tools go out of sync and behave differently depending on the path.

03

Manual handoffs are slow and error-prone

People spend hours exporting, cleaning, and importing data — and the errors quietly leak into your operations.

04

You depend on fragile one-off scripts

Ad-hoc scripts and manual processes break silently, and nobody knows until something goes wrong.

Capabilities

End to end, under one roof.

01

API Design & Engineering

Clean, documented, and secure APIs built to be consumed — not just exposed.

  • REST API design
  • Authentication and authorization
  • Rate limiting and security
  • API documentation
  • Versioning strategy
02

System Integration

Reliable connectors between the tools your business actually runs on.

  • Payment gateways
  • Messaging and notifications
  • Authentication providers
  • Third-party platforms
  • Legacy system connectivity
03

Data & Automation

Automatic data flows that keep systems in sync without manual steps.

  • Webhooks and event streaming
  • Data sync and mapping
  • Scheduled pipelines and jobs
  • Error handling and retries
  • Reconciliation and audit logs
04

Operational Reliability

Integrations that run themselves and tell you when they need attention.

  • Monitoring and alerting
  • Failure recovery
  • Security and compliance
  • Deployment strategy
  • Ongoing support

Working together

How we'll approach this project.

  1. 01

    Map

    We map the systems involved, the data that needs to move, and every manual step that exists today.

  2. 02

    Design

    We design the API contracts, data mapping, and failure handling before writing any code.

  3. 03

    Build

    We build the connectors and workflows with retries, logging, and security built in from the start.

  4. 04

    Test

    We test the real flows end to end — including the failure cases, not just the happy path.

  5. 05

    Operate

    We deploy with monitoring in place and support the integration as your systems evolve.

Technology

Built on the right foundation.

A glimpse of the stack we typically use for this type of engagement. We recommend the right tools for the job rather than applying one template to everything.

  • Node.js
  • TypeScript
  • REST APIs
  • Webhooks
  • Stripe
  • Razorpay
  • JWT / OAuth
  • MongoDB
  • PostgreSQL
  • Redis

Deliverables

What you walk away with.

  • Custom APIs
  • System integrations
  • Payment gateway integration
  • Messaging notifications
  • Authentication setup
  • Webhooks and data sync
  • Automation and pipelines
  • API documentation
  • Error handling and retries
  • Monitoring and alerts
  • Ongoing support

FAQ

Questions worth asking before you commit.

Anything with a documented API — payments, messaging, CRMs, accounting, shipping, authentication providers, and more. For systems without an API, we build the connector from the format they do provide.

A single well-defined integration typically takes one to three weeks. Multi-system data pipelines or custom API platforms take longer and are scoped after discovery.

Yes. We integrate with whatever stack you run today, whether that means connecting to an existing application or building a standalone service.

We build retries, idempotency, and alerting into the integration so failures are caught, replayed, and reported rather than silently losing data.

Yes. Every API and integration ships with clear documentation of endpoints, data models, and failure behaviour, so your team can understand and extend it.

Let's build

Your systems are already generating useful data. Make it flow.

Tell us which tools you use and where the manual work happens. We'll design the integration that removes it.
