Quick Answers

What payment rails are used for payout API transactions?

Payout APIs in India route transactions over IMPS (real-time, up to ₹5 lakh), NEFT (batch-based, any amount), RTGS (real-time, ₹2 lakh+), and UPI (real-time, up to ₹2 lakh for P2M). The optimal rail is selected based on amount, time sensitivity, and bank availability.

What is the typical payout API success rate?

Enterprise-grade payout APIs like NxtBanking's achieve 99%+ transaction success rates through multi-bank connected routing with automatic failover. Single-bank integrations typically achieve 90–95% success due to periodic bank downtime and maintenance windows.

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.
