Smart OTP Delivery

The Best OTP Delivery Strategy

Send OTP through WhatsApp first for better delivery, lower cost, and richer user experience. If delivery is not successful, automatically fallback to SMS or Telegram.

How it works

💬
1. Send via WhatsApp

Start with WhatsApp OTP because it is secure, modern, fast, and ideal for business messaging.

↓
⚠️
2. Check delivery status

If WhatsApp delivery fails, is unavailable, or the user cannot receive the message, trigger fallback automatically.

📲
3. Fallback to SMS or Telegram

Use SMS as a universal backup channel, or Telegram where supported, to maximize OTP reach and reliability.
