UPI Verification API – Real-Time VPA Validation
UPI Verification API
Are you worried about UPI fraud? The UPI Verification API from nxt Banking validates a customer’s Virtual Payment Address (VPA) in real time. With our API, you confirm both the VPA’s validity and the account holder’s name instantly, reducing fraud risk.
Why Use the UPI Verification API?
The UPI Verification API plugs into India’s NPCI database and:
Confirms whether the VPA belongs to an active bank account
Returns the linked account holder’s name

Therefore, businesses avoid failed transactions and fraudulent onboarding. Secure your platform with reliable VPA verification.

Quick Answers
What are the main UPI payment flows for businesses?
Businesses can use UPI Intent (customer-initiated via QR scan or payment link), UPI Collect (merchant-initiated payment request to customer's UPI ID), UPI Mandate (customer-authorised recurring auto-debit), and UPI QR (static for counter payments, dynamic for per-transaction amount binding).
How does UPI payment settlement work for merchants?
UPI payments from customers are received instantly into the merchant's settlement account. NPCI nets settlement daily; funds typically reach the merchant's bank account on T+1, though some payment processors offer intraday settlement for qualifying merchants.
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.
