Transactional SMS, DLT done for you.
One API for OTPs, alerts and order updates — sub-3-second delivery on direct operator routes, with DLT registration, sender IDs and templates handled by our team.
Direct routes, real compliance, no middlemen.
The SMS layer underneath your OTPs and alerts — and the fallback that keeps multi-channel auth reliable.
Three ways to wire it, one API.
Pick the flow that matches your product. Every one runs on the same endpoint, the same DLT registration and the same delivery webhooks.
Transactional SMS, direct route
Your app calls POST /v1/sms. QuickAuth checks the DLT header and template, routes the message on direct Jio, Airtel, Vi and BSNL routes, and posts the DLR webhook back the moment the handset confirms delivery.
WhatsApp-first, SMS fallback
The code goes to WhatsApp first. If it is not delivered inside the window, the same verify ID falls back to a DLT-registered SMS on its own — no second API call, no duplicate code.
Multi-channel routing
One verify ID, three roads. The router picks SMS, WhatsApp or voice per number from reachability and cost, and moves to the next channel if the first one fails.
SMS & DLT, answered.
Do I have to do DLT registration myself?+
No. We register your principal entity, sender IDs and SMS templates on Jio TrueConnect — the TRAI-mandated DLT registry — for you, usually within 24 hours, and keep the registry in sync as templates change. You stay compliant without touching the portal.
How fast is SMS delivery in India?+
Sub-3-second p95 on direct operator routes across Jio, Airtel, Vi and BSNL — no aggregator hops. Real-time DLR webhooks push delivered / failed status back to your system so every message is auditable.
What is the difference between transactional and promotional SMS on DLT?+
Transactional / service templates (OTPs, alerts, order and payment updates) are tied to a user action and are not subject to promotional time-window or scrubbing rules. Promotional SMS needs separate consent and DLT scrubbing. We register your templates in the correct category so they clear and deliver reliably.
Can SMS fall back to WhatsApp or voice automatically?+
Yes. One verification ID routes across SMS, WhatsApp and voice by reachability and cost — if a channel isn't reachable it falls back automatically, so a number that can't receive SMS still gets verified.
SMS that just works in India.
DLT-registered, sub-3s, INR-billed — and ready to fall back to WhatsApp or voice.
