What Is WhatsApp Authentication?

WhatsApp Authentication is a business verification solution that enables brands to authenticate users using WhatsApp messages rather than traditional SMS. It’s a key feature of the WhatsApp Business API that ensures instant OTP delivery.

How It Works

01

User Initiates Verification

The user enters their mobile number and performs a secure action, such as payment and login.

02

OTP Generated via API

Your system sends a request to Getgabs WhatsApp Authentication API to generate a secure one-time password (OTP).

03

OTP Delivered on WhatsApp

The OTP is directly sent to the user’s main WhatsApp account with built-in security.

Types of WhatsApp Authentication Templates

One-Tap Autofill Authentication Templates

A seamless bridge that connects WhatsApp with your app. It is where users receive a message with the “Autofill” button, and when clicked, it automatically opens your app and enters the code.

  • User Experience: "One-Click Login." No typing or switching screens required.
  • Best For: Enhancing registration rates on Android devices.

  • Best For: Web-based platforms and cross-platform mobile apps.

Why Choose WhatsApp for Authentication?

WhatsApp verification is not just about security; it's about offering a premium user experience that SMS can’t.

Linked Device Security

Secure your every authentication message with Linked Device Security. OTPs are delivered only to the user’s primary WhatsApp device, whereas messages on WhatsApp Web and Desktop stay hidden.

Superior Global Delivery Rates

Network issues often lead to failed SMS. With WhatsApp authentication, you get guaranteed OTP delivery across the globe with 99% success rate.

Reduced Friction & Higher Conversions

Remove “copy-paste” hurdle using features such as one-tap autofill and zero-tap authentication. Instant logins lead to fewer abandoned carts and higher user retention in your app.

Verified Brand Trust

When users get a WhatsApp OTP from a verified profile (logo & blue tick), they feel safer than receiving a code from a random 6-digit SMS sender ID.
