Authentication Templates in Mark360.ai

Authentication templates allow businesses to send secure one-time passcodes (OTP) to users during key identity verification steps such as login, registration, account recovery, or fraud detection challenges. These templates are compliant with WhatsApp's guidelines and include required buttons for OTP interaction.

When to Use Authentication Templates​

Use an authentication template only when you’re delivering a one-time password (OTP) or verification code via WhatsApp.

Ideal Use Cases:​

  • New account signup
  • Password reset
  • Identity verification
  • Suspicious login detection

📝 Sample Authentication Message Templates​

Here are some WhatsApp-compliant samples:

  • {{1}} is your verification code.
  • {{1}} is your verification code. For your security, do not share this code.
  • {{1}} is your verification code. This code expires in 15 minutes.

Only preset text and OTP buttons are allowed. Media, emojis, and URLs are not supported.

Mandatory Template Components​

Fixed Text{{1}} is your verification code.
Security Disclaimer (Optional)For your security, do not share this code.
Expiry Warning (Optional)This code expires in <NUM_MINUTES> minutes.
Button (Required)Copy Code or One-Tap Autofill
No Custom Body/Text AllowedUse only pre-approved Meta text

OTP Button Types​

1. Copy Code​

  • Copies the OTP to clipboard
  • Users must manually paste it into your app

2. One-Tap Autofill​

  • Seamlessly sends OTP to your app
  • Works only on Android
  • Requires app handshake setup with Meta

Even if you choose Zero-Tap Setup, the template must include buttons as a fallback.

Handshake Setup for One-Tap​

To enable One-Tap Autofill, you’ll need:

FieldDescriptionExample
<PACKAGE_NAME>Android app’s package namecom.mark360.app
<SIGNATURE_HASH>Your app signing key hash (see Meta docs)K8a%2FAINcGX7

Contact your developer team to generate the Signing Key Hash.
