New WhatsApp Authentication Template Requirements - May 2023

WhatsApp requires new authentication templates to include one-time password (OTP) buttons in order to be approved. These new authentication templates are referred to as compliant authentication templates. They must follow the format predetermined by WhatsApp (please see link above for details) and cannot be edited by the business. 

The compliant authentication template format is supported in Content Template Builder and Legacy WhatsApp Templates. There are some differences in what is supported in each platform:

  • Content Template Builder: Support for basic authentication message, and optional expiry code and security advisory.
  • Legacy Templates: Support for basic authentication message and automatic inclusion of security advisory.

Notice: As highlighed on Meta’s public documentation, authentication templates are not currently supported in India. Any Authentication messages sent to Indian WhatsApp numbers will result in error 63024. You will need to use alternative methods to send OTP type messages to Indian numbers, such as Twilio's Verify API:
