Use Cases

OTP Verification

Two-factor authentication and verification codes via WhatsApp. Implement secure OTP delivery for login, signup, and transaction verification.

When to use OTP verification

Login from a new device. Confirm a large transfer. Reset a password. OTP adds a second factor—something the user has (their phone) plus something they know. WhatsApp delivers the code quickly and reliably.

What you get

Login Verification

Verify user identity during login with OTP. Send a code when someone signs in from a new device. Simple, effective security.

Account protection

Transaction Verification

Confirm high-value transactions via WhatsApp OTP. Banking, payments, or sensitive actions—get explicit user confirmation.

Fraud prevention

Password Reset

Secure password reset flows with OTP verification. User requests reset, gets a code on WhatsApp, enters it. No email phishing risk.

Secure recovery

Frequently asked questions

What is WhatsApp OTP verification?

OTP verification sends a one-time code to the user via WhatsApp. They enter the code in your app to confirm identity—for login, transactions, or password reset. WAPing delivers the message through your connected WhatsApp number (QR-linked session); it is not Meta’s official WhatsApp Business API product.

How do I implement WhatsApp OTP in my app?

Create an account at app.waping.app, upgrade to Starter or higher for REST API access, then create an API key and connect a WhatsApp number via QR code. When you need to verify a user, call our send-message API with your OTP message format and the code. The user receives it on WhatsApp and enters it in your app.
