Quick Answers
What makes a good fintech API integration?
A well-built fintech API integration covers: proper OAuth 2.0 authentication, idempotency keys on every write request, webhook HMAC signature verification, exponential-backoff retry logic for transient errors, and a status-query fallback for ambiguous outcomes. NxtBanking's sandbox environment lets you test all these scenarios before production.
How do I handle failed transactions in a payment API?
Categorise failures: (1) Hard failures (invalid account, KYC mismatch) — do not retry; notify user. (2) Transient failures (timeout, 5xx) — retry with idempotency key and exponential back-off. (3) Ambiguous (no response) — call the transaction status endpoint before retrying to avoid duplicate processing.
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.
