Hi Hunters! 👋
Ever had users complain they never received the SMS verification code? Or paid $0.10 per message that never delivered?
I built WhaOTP to fix this. It uses WhatsApp—the app already on everyone's phone—for OTP verification.
It's simple:
Send OTP request with phone number
User gets WhatsApp message with 4-digit code
User replies with the code
Your app gets verification status
Why devs love it:
• 2 API calls. That's it.
• Works globally
• 3 attempts & 300s expiry
• No SMS costs
• 5-minute integration
Code snippets for cURL, Python, Node.js, PHP, Go on the site.
Launch your auth system in minutes. Not months.
