Template messages are a special message type available to businesses for use to send notification type messages to consumers. Businesses can register content for their most commonly used messages and simply send the relevant variable parameters instead of recreating the entire message during the API call each time it is used.
For the consumers who receive a notification message from your verified business for the first time and do not have the business saved as a contact in their phone book, the WhatsApp application will recognize the registered template and display the message without any warnings. This will reduce the likelihood of your messages being marked as spam by the consumer.
Once your business is verified by WhatsApp, you can proceed with the registration and approval of Template Messages. Read more about how to create a WhatsApp message template for approval.
