The flow I would like to implement is:

1. A user signs up in the mobile app and enters their phone number.

2. The system generates a one-time verification code (OTP).

3. The OTP is sent to the user via WhatsApp message.

4. The user enters the code in the app to confirm their phone number.

My questions are:

• Is it possible to send WhatsApp OTP messages using Zoho Marketing Automation workflows?

• Can Marketing Automation send dynamic values (like OTP codes) inside a WhatsApp template triggered by an external event (API or webhook)?

• If this is not supported natively, what would be the recommended way to implement this using Zoho tools?
