Service
API Development & Integration
Make the systems you already run talk to each other
Overview
What this service covers and who it is for
Most businesses do not need another system. They need the four they already run to stop being islands. Orders on the website, stock in the ERP, invoices in Tally and conversations on WhatsApp — each holding a piece of the truth, reconciled by a person with a spreadsheet.
We build the connections between them: documented, monitored APIs that move data reliably and tell you when something goes wrong instead of failing quietly.
What we integrate
Payment gateways (Razorpay, PayU, CCAvenue, Stripe, PayPal), WhatsApp Business API, SMS gateways on DLT-compliant Indian providers, transactional email, Tally and other accounting software, courier and logistics tracking, GST and e-way bill services, and marketplace APIs.
Built to fail safely
Third-party services go down. Integrations we build retry with backoff, queue what cannot be delivered, and alert a human when intervention is genuinely needed — so a gateway outage does not silently lose you a day of orders.
- Retry and queue handling for outages
- Alerting when something genuinely breaks
- Full API documentation handed over
- Sandbox testing before anything goes live
What's Included
Payment Gateways
Razorpay, PayU, CCAvenue, Stripe and PayPal with proper webhook handling and reconciliation.
WhatsApp Business API
Template-approved transactional messages for orders, dispatch and payment reminders.
Accounting Sync
Push invoices and vouchers into Tally or your accounting package without re-entry.
Logistics & Tracking
Courier APIs for AWB generation, live tracking and automatic delivery status updates.
Custom REST APIs
Documented, versioned and authenticated APIs so partners and apps can connect safely.
Monitoring & Alerts
Failure alerts and retry logic, so a broken integration is noticed within minutes.
Business Impact
Data entered once
The same order stops being typed into three systems by three different people.
Faster payment collection
Automated reminders and online payment links measurably shorten the receivables cycle.
Fewer status calls
Customers receive updates automatically instead of calling to ask.
Reconciliation that adds up
Gateway settlements matched against orders automatically rather than line by line.
How We Deliver It
-
01
Systems audit
We map what you run, what data each system holds, and where it currently gets re-typed.
-
02
Integration design
Direction of flow, frequency, conflict rules and failure behaviour agreed up front.
-
03
Sandbox build
Built and proven against provider test environments before touching live data.
-
04
Controlled go-live
Phased switch-on with the manual process still available as a fallback.
-
05
Monitoring setup
Alerts, retry policy and a documented runbook for when a provider has an outage.
