API development and system integration

Your tools talking to each other, instead of through people copying data between them. We design and document APIs, connect payment, CRM, accounting and marketplace systems, and keep data in sync both ways.

What’s included

API design, build and documentation

REST or GraphQL APIs with clear documentation your partners can use.

Payment, CRM and accounting connections

Razorpay, Stripe, Zoho, HubSpot, Salesforce, Tally and others.

Marketplace connections

Orders, stock and prices synced with marketplaces wherever they offer an API.

Two-way syncs, webhooks and events

Changes in one system reach the others quickly, with retries when something is down.

Microservices

A large system split into services that can change and scale separately, when that genuinely helps.

When it makes sense

  • Someone on your team copies data between tools every day.
  • Partners or customers want to connect to your system.
  • Two systems disagree and nobody knows which one is right.

What you get

  • API documentation
  • Integrations with logging and retries
  • Alerts when a sync fails
  • A list of every connection and what it moves

Tools we work with

Questions about APIs and integrations

What if a tool has no API?

We look for exports, emailed reports or file drops we can automate. As a last resort, a bot can work the tool’s screens the way a person would.

What happens when one side is down?

Every integration retries, logs what failed and alerts someone, so nothing is lost quietly.
