Quick Answers

What is KYC and why is it required in fintech?

KYC (Know Your Customer) is the mandatory identity verification process required by RBI under its Master Direction on KYC. It involves verifying a customer's identity (via Aadhaar, PAN, passport, or other documents) and address before onboarding them for financial services.

What is the difference between KYC and eKYC?

Traditional KYC uses physical document submission and in-person verification. eKYC (electronic KYC) uses Aadhaar OTP or biometric authentication via UIDAI for instant, paperless verification. eKYC is faster, cheaper, and enables digital-first onboarding for fintech apps.

Is NxtBanking RBI-compliant for payment APIs?

Yes. NxtBanking operates through RBI-licensed partner banks for all payment services (IMPS, NEFT, RTGS, UPI) and is NPCI-certified for BBPS, AEPS, and UPI flows. All APIs follow RBI's Master Directions on payment aggregators, KYC, and PMLA obligations. We maintain audit logs, data localisation, and consent frameworks compliant with the DPDP Act 2023.

How does NxtBanking handle API downtime and failover?

NxtBanking uses a connected-banking architecture that links a single API credential to multiple RBI-licensed partner banks. When one bank's rails experience degradation or maintenance, the API automatically routes to the next available bank — with no code change required on the client side. This multi-bank failover is what delivers 99%+ transaction success rates and 99.9% API uptime SLA for enterprise clients.

What does it cost to integrate NxtBanking APIs?

NxtBanking offers pay-as-you-go pricing with no setup fees and no minimum commitment for most APIs. Typical pricing: IMPS/UPI payout ₹3–₹8 per transaction, NEFT ₹1–₹3, BBPS bill payment ₹0.50–₹3, AEPS cash withdrawal ₹2–₹5. Enterprise clients on committed volumes negotiate flat-rate pricing. Sandbox access is free and unlimited. Contact sales for a custom quote based on your expected transaction volume.
