SMS platforms are built for marketers. You need one built for engineers.
A financial OTP that takes eight seconds isn't an OTP — it's a customer-support ticket. A transaction alert that misses one customer in a hundred is a compliance risk and a reputational risk.
Most SMS platforms were designed for promotional blasts. Regulated messaging needs dedicated routes, strict idempotency, India-resident infrastructure, and an audit trail your compliance team can hand straight to a regulator.
Sub-1s
median OTP delivery on clean DLT traffic — on a priority route isolated from promotional bulk.
A messaging stack regulated messaging actually deserves.
Priority OTP routes, DLT-approved transactional templates, WhatsApp for KYC flows, and a compliance layer designed around DPDPA 2023.
OTP API with priority route
Dedicated infrastructure separated from promotional bulk. Automatic retry, idempotency keys, and fallback logic for failed OTPs.
Transaction alerts over DLT-approved SMS
Pre-registered templates for every common event — credit, debit, UPI, failed transaction, card swipe — with carrier-level audit logs.
KYC and onboarding over WhatsApp
Document upload, selfie submission, and follow-up questions — in the customer's language, with end-to-end encryption in transit.
Compliance and audit layer
DLT entity, Sender ID, and PE certificate management in the dashboard. Data residency in India. Exportable logs for regulators.

Questions our engineering and compliance teams get most.
Do you sign Data Processing Addendums with regulated customers?
Yes — our standard DPA is available at /legal/dpa. Our team can also review your counter-signed version for enterprise agreements.
Are your OTP routes dedicated?
Yes. OTP traffic runs on a separate priority route, isolated from bulk promotional traffic, with automatic retry on failure.
Can I enforce idempotency on OTP API calls?
Yes. Every /v1/otp/send request accepts an idempotency_key header so retried requests never trigger duplicate OTP sends or extra charges.
What audit trail do I get for regulators?
Every message is logged with timestamp, sender, recipient, template ID, carrier, delivery status, and cost. The full log is exportable per account and per sub-account.
How do we integrate the fintech SMS API into our stack?
A single API call per message, with idempotency keys, delivery-status webhooks, and pre-approved DLT templates for OTP and transaction-alert flows. Most banking and fintech teams complete integration and DLT onboarding in under a week.
