WhatsApp message templates expand the content you can send recipients beyond the standard message template type to include these components: headers, media and buttons. That is, the template allows you to predefine the configuration of text message, media and buttons features and personalized fields (placeholders) that provide additional information.
If you want to create the message template via Templates API, you need to provide the WhatsApp Business Account ID (WABA) or the unique identifier of the sender.
To know how to create a text message template go to the Creating & Sending WhatsApp Text Message Template section or create a media message template go to the Creating & Sending Media Message Template section.
