What does a Razorpay integration involve?
A Razorpay integration connects your website, app or ERP to Razorpay for checkout, UPI, payment links and subscriptions, handles webhooks for success, failure and refund events, and reconciles settlements against invoices. Stack18 builds it with retries, idempotency and an audit trail.

Razorpay Integration questions.
Do you handle PCI and card data?
Card data is handled by Razorpay's hosted checkout, so your systems do not store card numbers. We design the integration to keep it that way.
Can you integrate with our ERP or Tally?
Yes. We post payments and settlements to your accounting records and flag mismatches for review.
Do you support other gateways too?
Yes. We can design a gateway layer so you can add or switch providers without rewriting the business logic.
How do you stop duplicate or lost payments?
With signature-verified webhooks, idempotent processing and a retry queue, so a repeated or delayed event cannot create a double entry or a lost order.
How long does it take?
A standard checkout and webhook integration is scoped in a two-week Discovery Sprint. Reconciliation and subscription logic depend on your accounting set-up.
Let's scope your Razorpay Integration project.
