The High Cost of a Delayed OTP
Every second counts during an onboarding or checkout flow. If an OTP takes longer than 15 seconds to arrive, over 40% of users will abandon the process—costing you direct revenue and ballooning your customer acquisition costs. At SMS Dekho, OTP APIs bypass standard traffic lanes. They are injected into a dedicated, high-priority queue engineered purely for multi-factor authentication (MFA).
Automatic Multi-Protocol Failovers
Telecom networks are inherently erratic. A cell tower could be congested, or an operator's node might drop. Our Smart Failover Algorithm monitors packet latency in real-time. If an SMS OTP is not confirmed delivered within 5 seconds, the system automatically pivots and delivers the pin via an automated Voice Call or WhatsApp message—ensuring your customer gets verified no matter what.
API Built for Developers
Integrating robust security should not require weeks of engineering. SMS Dekho provides RESTful APIs equipped with idempotent keys to prevent duplicate pin firing. Webhooks fire instant DLR (Delivery Reports) back to your backend, allowing your frontend UI to dynamically show "Resend OTP" buttons exactly when required.
