Features Built for Developers
Everything You Need to Send OTPs
A complete OTP platform designed for Indian developers who want reliability without complexity.
Skip the weeks-long DLT registration process. We handle all compliance so you can focus on building.
Sign up, get your API key, and start sending OTPs. Just a quick verification and you are good to go.
One POST request to send an OTP. Clean JSON responses. Works with any language or framework.
Automatic failover between SMS providers ensures your OTPs always get delivered.
Built-in idempotency keys prevent duplicate OTP sends even with network retries.
No monthly fees. Add funds to your wallet and pay Rs 0.25 per OTP sent.
Track every message with delivery status updates. Full audit trail for all OTP requests.
OTP codes are bcrypt-hashed. API keys are SHA-256 hashed. Your data is always protected.
Designed for Production
OTP codes are bcrypt-hashed before storage — never stored in plaintext. API keys are SHA-256 hashed. All communication over HTTPS. Your users' data is protected at every layer.
We route OTPs through multiple SMS providers (Twilio, MSG91) with priority-based fallback. If one provider fails with a service error, we automatically retry with the next provider.
Every OTP send request requires an idempotency key. If you accidentally send the same request twice (network retry, double click), the duplicate is ignored. No double-sends, ever.
Track every OTP from queued to delivered. Each message includes a full status history timeline with timestamps, provider details, and cost tracking.
Upcoming features
We are investing beyond core SMS OTP: deeper DLT tooling, WhatsApp with campaign scheduling, and SDK-first integrations for mobile teams. Timelines will ship in product changelog order—this is what we are building toward next.
If you need something that is not on the public roadmap yet, email us at startmessagingdotcom@gmail.com with your volume, timelines, and a short technical brief—we reply to qualified requests with a feasibility note and next steps.
