About This Topic
NxtBanking provides a comprehensive suite of B2B fintech API services — Payout, BBPS, AEPS, UPI Collection, KYC, Recharge, DMT, Micro-ATM, and Travel APIs — plus custom fintech software development, white-label platform builds, and mobile app engineering. All API services are available under one master agreement, one credential, and one unified dashboard, with RBI-licensed bank rails and NPCI certification built in.
Quick Answers
What APIs does NxtBanking provide?
NxtBanking provides 18+ fintech APIs on a single platform: Payout (IMPS/NEFT/RTGS/UPI), BBPS Bill Payment, AEPS, UPI Collection & QR, KYC & Identity Verification (Aadhaar, PAN, Bank, Driving Licence, Voter ID, RC), Mobile & DTH Recharge, Domestic Money Transfer, Micro-ATM, Pay-In/Escrow, and Travel (Bus, Hotel, Air, IRCTC).
How long does NxtBanking API integration take?
Sandbox access is available immediately after sign-up. For most APIs, a developer can complete sandbox integration in 2–5 business days. Production go-live, including KYC, compliance review, and bank account setup, takes 7–21 business days depending on the API type.
What support does NxtBanking provide during integration?
NxtBanking provides dedicated technical onboarding (email + video call), comprehensive API documentation with Postman collections and code samples, a sandbox with simulated error scenarios, and email/chat support for integration queries. Enterprise accounts get a dedicated technical account manager.
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.
