You may use broadcasts To Send
WhatsApp allows only template messages to be broadcasted to the end-users as business-initiated messages.
When end-users reply to any message from the business, they have automatically opened the 24-hour response window in which the business can send all types of free-form messages.
If the 24-hour window lapses, you must re-establish contact through the use of message templates.
