PayPal Integration Services
Payment integration bugs are the most expensive kind
A bug in a payment flow doesn't just create a support ticket - it can mean charging customers incorrectly, failing to fulfill paid orders, or missing subscription renewal events. We treat payment integration testing with a level of rigor that matches those stakes: real sandbox transaction testing across success, failure and edge cases, not just a single happy-path checkout tested once.
What we build
- Checkout flow integration - one-time payments through PayPal's standard or advanced checkout, matched to your actual product flow
- Subscription billing setup if you have recurring charges, including proper handling of renewal, cancellation and failed payment events
- Webhook handling for asynchronous payment events (delayed confirmations, disputes, refunds) processed reliably, not just the immediate checkout response
- Reconciliation support - matching PayPal's transaction records against your own order/subscription database to catch discrepancies early
Our process
1. Map your real payment scenarios
One-time vs. subscription, refund policy, what happens on a failed payment - all defined before building, not improvised during integration.
2. Build against PayPal's sandbox
All development and testing happens in sandbox mode first, never against real transactions during development.
3. Test edge cases explicitly
Failed payments, disputed transactions, subscription cancellations - each tested deliberately, not just the successful checkout path.
4. Go live with monitoring
Real transaction monitoring from the first live payment, so any issue is caught immediately rather than discovered from a customer complaint.
Pricing
Rs 40,000-180,000 depending on whether it's one-time checkout or subscription billing, and how many edge cases need handling.
