FREQUENTLY ASKED QUESTIONS

Common Questions About Payment Gateway Integration

Clear, honest answers to the questions clients ask us most before kicking off an engagement.

For domestic Indian transactions, Razorpay, Cashfree, and PayU are the clear leaders due to their high UPI success rates and developer-friendly APIs. For international payments, Stripe and PayPal are optimal.

No. We strictly implement tokenized payment flows where sensitive card numbers are processed directly by the PCI-DSS Level 1 certified gateway. No card details ever touch your server, keeping you 100% compliant and secure.

Webhooks are server-to-server notifications sent by the payment gateway immediately when a transaction settles. Even if a customer closes their browser window before redirecting, our webhook listener updates your database and confirms the order automatically.

Indian payment gateways require standard corporate KYC: Company PAN, Certificate of Incorporation or GST registration, canceled cheque, director ID proofs, and a compliant website with Terms, Privacy Policy, and Refund Policy pages.

Yes. We can automate GST-compliant invoice generation upon payment completion and integrate admin buttons for one-click partial or full refunds directly through the gateway API.
