02 — ENGINEAPI DEVELOPMENT

Your systems should talk to each other. Without babysitting.

Broken integrations and missing APIs are silent revenue killers. As an API development agency for Indian startups, we build reliable, documented, and monitored API infrastructure — so your tools stay connected and your team stays focused.

THE PROBLEM

Every broken integration is a manual process waiting to happen.

When APIs fail silently, your team fills the gap with spreadsheets, copy-paste workflows, and morning check-ins to confirm that the previous night's data transfer actually worked. Every missing integration is a hidden headcount cost.

Good API infrastructure means your systems stay connected, your data stays consistent, and your team spends their time on work that compounds — not on monitoring whether the tools behaved overnight.

Two critical tools don't talk to each other — data gets copied manually
A third-party integration was built once by a freelancer and breaks constantly
No API documentation — every integration requires a Zoom call to explain
Webhook events drop silently with no retry logic and no alerting
No rate limiting — a single bad actor can take down the entire backend
WHAT WE BUILD

APIs that are reliable by design.

Every API development engagement includes six deliverables — design, build, documentation, auth, monitoring, and integrations. Not a single endpoint without observability.

01

RESTful API Design & Build

Clean, versioned REST APIs with proper resource naming, HTTP method conventions, pagination, filtering, and error responses — built to a standard any developer can understand and extend.

02

Third-Party API Integrations

WhatsApp Business, Razorpay, Stripe, Google Workspace, Slack, Salesforce, HubSpot, or any other service your product needs to connect with — handled as a complete integration, not a tutorial.

03

Webhook Infrastructure

Inbound webhook receivers, event processing queues, retry logic, and delivery monitoring — so your system reacts to external events reliably without dropping data.

04

Authentication & Rate Limiting

API key management, OAuth 2.0, JWT authentication, and per-client rate limiting — so your API is secure and your infrastructure isn't vulnerable to a single abusive caller.

05

API Documentation

Swagger/OpenAPI spec auto-generated from your codebase, plus a developer-facing documentation portal — so partners and your own team can integrate without a call.

06

Monitoring & Alerting

Response time tracking, error rate dashboards, uptime monitoring, and Slack alerts for anomalies — so you know about API failures before your customers do.

WHO THIS IS FOR

Is this the right fit?

Our API integration services are for teams where connectivity between systems is a bottleneck. If you fit below, let's map the integration.

A startup that needs two or more critical systems integrated and working reliably
A SaaS product that needs to expose an API for partner or enterprise integrations
A team with a broken legacy integration that needs a proper rebuild
A company building a data pipeline between internal and external systems

NOT A FIT: Simple Zapier/Make automations that don't require custom code, or API builds without a defined system on both ends.

"We had webhook events dropping silently for months. We only discovered it when a client complained. The rebuild included proper retry logic and alerting — we've had zero silent failures since."
