APIs your partners can actually build on.
Versioned, documented and authenticated — so integrating with you isn't a support ticket.
Sound familiar?
- “Your partners keep emailing your developers because the API has no documentation.”
- “Changing one endpoint breaks three integrations you didn't know existed.”
- “Every new integration is a bespoke project because there's no consistent interface.”
If any of those land, this is the page for you. Here's how we approach it.
What you get
What api development actually changes.
Integration without hand-holding
Documentation good enough that a partner can integrate without talking to your team.
Change without breaking people
Proper versioning and deprecation windows, so improvements don't take down someone's production system.
Secure by design
Authentication, rate limiting, input validation and scoped permissions on every endpoint.
Fast under load
Caching, pagination and query efficiency so response times hold when traffic multiplies.
Observable
Logging and monitoring per endpoint, so you know what's slow and who's calling it.
A platform, not a one-off
A consistent interface means the next integration is configuration rather than a project.
What's included
Everything in the engagement.
REST & GraphQL
Whichever suits your consumers — often both, over the same core.
OpenAPI documentation
Interactive docs generated from the code, so they can't go stale.
Authentication
API keys, OAuth 2.0, JWT and scoped access per client.
Rate limiting
Per-client quotas that protect you from a single misbehaving integration.
Versioning
Clear version strategy and deprecation policy.
Webhooks
Outbound events with retries and signature verification.
Third-party integrations
Razorpay, Stripe, Tally, Zoho, WhatsApp Business, Salesforce, and more.
Sandbox environment
A test environment so partners can build before going live.

REST for straightforward resource access and public APIs where caching matters. GraphQL when clients need to fetch varied, nested data and you want to avoid a dozen bespoke endpoints. Plenty of systems justify both.
Often. Options include database-level integration, file-based exchange, screen automation as a last resort, or building an API layer over the legacy system. We'll be honest about which of these is fragile.
Authentication on every endpoint, scoped permissions, rate limiting per client, validation of all input, TLS everywhere, and secrets kept out of the codebase. We also log enough to investigate an incident.
Generated from the code via OpenAPI, so it can't drift from reality — hand-maintained documentation is always eventually wrong. Partners get an interactive console to try calls against a sandbox.
Yes — Razorpay, PayU, CCAvenue, Cashfree and UPI, including webhook handling, reconciliation and the failure cases that matter more than the happy path.
