You can use the WhatsApp Business API to send text messages, media/documents, and message templates to your customers. You should use the

There are no charges for these messages.
At any time, you can send business-initiated messages to customers who have opted-in. Throughout the documentation, these messages are also called notifications, message templates, or templated messages.
