Frequently Asked Questions
What is the WhatsApp Business Platform (Cloud API)?
It's the Meta-hosted API tier of WhatsApp Business that lets a brand send and receive messages programmatically — no phone farm, no chatbot provider lock-in, and full template/media/interactive-message support.
How much does WhatsApp Business API cost in India?
Meta charges a conversation-based price (currently ~₹0.11–₹0.88 per conversation depending on category: utility, marketing, authentication, service). NxtBanking adds a flat platform fee per account and does not mark up Meta's conversation fees.
Do I need a Meta-verified business?
You need a Facebook Business Manager and a verified business for green-tick status and higher message limits. NxtBanking guides you through BM setup, document submission, and verification as part of onboarding.
What templates are allowed?
Utility (transactional), authentication (OTP), and marketing templates — each with its own Meta policy. We help draft, submit, and maintain templates to keep them within policy and minimise rejections.
Can I send OTPs via WhatsApp?
Yes, via authentication-category templates. Typical delivery latency is under 3 seconds and success rate is higher than SMS OTP for most operators — a strong fallback for SMS-DND users.
Does NxtBanking integrate CRM data into WhatsApp flows?
Yes. We wire up Zoho / Salesforce / HubSpot / custom CRMs to trigger context-aware messages (abandoned cart, order status, payment reminders, support tickets) via webhooks and APIs.
How do I handle opt-in and opt-out?
WhatsApp requires explicit user opt-in before marketing messages. Our platform captures opt-in consent, logs it (audit-ready for DPDP Act 2023), and honours STOP / UNSUBSCRIBE requests automatically.

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.
