Services
APIs & Integrations
Most products live or die by what they connect to. We design clean REST APIs and wire your app into the services that matter - payment gateways, analytics, auth, and the internal systems your business already runs on.
What we do
REST API design
Well-documented, versioned REST APIs on Django and Node, with auth, rate limiting and sensible error contracts.
Payment gateways
Checkout, subscriptions and invoicing wired to payment and UPI providers, with webhooks and reconciliation handled.
Analytics & tracking
Product and marketing analytics integrated cleanly, with event schemas you can actually trust.
Business systems
Connecting CRMs, ERPs and internal tools so data flows automatically instead of through copy-paste.
Webhooks & sync
Reliable event-driven sync between systems, with retries, idempotency and dead-letter handling.
Outcomes
- Third-party services integrated without lock-in
- Payments and billing wired with proper reconciliation
- Event-driven sync that survives failures and retries
- APIs documented well enough that other teams self-serve
Stack
Questions
Can you integrate a service that has a messy API?+
Yes - that's most of the work. We wrap awkward third-party APIs behind a clean internal contract so the rest of your app stays simple.
Do you handle payments and subscriptions?+
Yes, including checkout, recurring billing, webhooks and reconciliation - the same patterns we run in Caryaa's GST billing and UPI flows.
