WhatsApp Message Templates are fixed reply templates that you can use when responding to your customers’ inquiries in Engage. A support agent who wishes to reply to a customer after 24 hours of receiving the message must use WhatsApp message templates according to WhatsApp's terms of service.
Note:
Currently, Engage only supports plain text-based message templates.
Updating and changing message templates is managed through the WhatsApp Business Manager. Please refer to Meta's help center for steps on creating message templates for your WhatsApp Business account.
After your message templates have been created and approved, they will be available to use in Engage. Open the WhatsApp message in Engage and click on Manage Templates. Then, select one of the templates with the WhatsApp icon.
