• 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.

• 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.
