WhatsApp Template messages use pre-approved message templates called MTMs for outbound notifications such as delivery alerts and appointment reminders. They cannot be used for marketing. You must use a WhatsApp Template Message if more than 24 hours have elapsed since the user last responded to you. Any other type of message will fail.

There are 10 notification types as given below, each with allowed use cases. Each template is language and country-specific. WhatsApp processes each approval request for a new template or an update to an existing template. Approvals can take up to four business days.
