API integration that does not fail quietly at 2am
Integrations are where most systems break: a rate limit, an expired token, a webhook that fired twice. We build them with typed clients, idempotent handlers, queues with retries and monitoring that pages a person before a customer notices — so the connection between your systems is the reliable part, not the fragile one.
Systems we connect
Anything with an API, an export or a database — and a few things without.
- Payments: Razorpay, Stripe, PayU, UPI flows and subscription billing
- Messaging: WhatsApp Business API, SMS, email and push notifications
- CRM and marketing: HubSpot, Zoho, Salesforce, Meta and Google lead forms
- ERP and accounting: Tally, Zoho Books, SAP Business One, custom ERPs
- Maps and logistics: Google Maps, Mapbox, delivery and tracking APIs
- AI models and vector databases through tool calling and queues
Reliability built in
Every integration ships with typed request and response models, idempotency keys on writes, exponential backoff, a dead-letter queue for failures, and dashboards for volume, latency and error rate. When a vendor changes an API, the type check fails in CI before production does.
Two-way sync done carefully
Bi-directional sync between, say, a CRM and an ERP is where duplicated records and overwritten data come from. We define a source of truth per field, log every change with its origin, and provide a reconciliation report so conflicts are visible instead of silent.
Deliverables at handover.
- Typed integration clients with documentation
- Queue, retry and dead-letter handling
- Monitoring dashboards and alerting
- Reconciliation reports for two-way syncs
- Credentials and infrastructure in your accounts
Every project also includes what is listed on the features page and follows the six-stage process. Pricing follows one of three engagement models.

API integration: what people ask.
Can you integrate the WhatsApp Business API?
Yes. We handle business verification, template approval, inbound webhooks and outbound messaging, and connect it to your CRM or booking system.
What happens when a third-party API goes down?
Requests queue and retry with backoff, failures land in a dead-letter queue for review, and an alert goes to your team. Nothing is lost and nothing is silently dropped.
Do you build integrations for existing software we did not write?
Frequently. We start with a short audit of the existing system and its API surface, then scope the integration against what is actually available.
Where this service has done the most.
Often combined with.
