Integrate secure numerical OTP delivery and verification into your system. Secure logins, payments, and registrations with PingDart's fast, telecom-direct OTP API in India.
PingDart provides a developer-friendly OTP generation and verification platform. With our specialized endpoints, you don't even need to maintain verification codes or expiration states on your own backend.
Simply call our generation endpoint, and we will construct a high-entropy numeric token, dispatch it to the user's mobile carrier, and manage its validity duration. Once the user submits their input, send it to our verification gateway for immediate check.

}'Track delivery timings down to the millisecond. PingDart's dashboard and webhooks feed you real-time metadata on whether codes reached devices, which operators were route paths, and exact network latencies.
Monitor status metrics for conversion, and identify if a user fails login verification due to handset network issues, blocking codes, or signal degradation.
Keep your verification conversion rates close to 100% with our smart, automated failover capabilities.
If direct connectivity to Jio or Airtel has a localized outage or traffic lag, the system automatically redirects delivery through alternative telecom routes within milliseconds.
Enable automated API-level retry flags. If an operator reports the message is undelivered within a 15-second window, we retry utilizing high-priority channels.
Set up rules to convert SMS OTPs into voice call OTPs or WhatsApp message delivery fallbacks automatically if SMS cannot be received after a specified duration.
Simple, transparent, volume-based pricing. No monthly commitments or hidden setup charges.
We provide cloud infrastructure and communication APIs that developers trust. Compare our security features.
We connect directly with carrier SMSCs in India, avoiding middle hops that introduce failure states and latency bottlenecks.
Verification tokens are hashed in memory and deleted completely upon expiry or successful match. No raw codes are stored.
Protect your billing balance. Define request limits per mobile number, device IP, or browser session to avoid denial-of-service SMS attacks.
Consume detailed network payload notifications on delivery confirmation or error events directly inside your web application.
