# 63052: Legacy WhatsApp Template Used

Log Type: APPLICATION

Log Level: WARNING

## Description

Twilio detected that this WhatsApp message was sent using the legacy WhatsApp templates system. This system is end-of-life. Send WhatsApp templates with the Content Template Builder or the Content API, and use `ContentSid` and `Content Variables` when you send the message.

### Possible causes

* You sent a WhatsApp template with the legacy WhatsApp Templates product instead of a Content Template.
* You used the `body` field to match or send a template that now must be sent with `ContentSid` and `Content Variables`.

### Possible solutions

* Create and manage the template in the Content Template Builder or the Content API.
* Send the template with `ContentSid` and `Content Variables` instead of the legacy `body`-based template flow.
* If you need to change an existing template, duplicate it in the Content Template Builder, update the copy, and submit it again for WhatsApp approval if required.
