WhatsApp’s Session messages and Template messages

The Zoko WhatsApp Business API makes 3 types of communication possible.

Outgoing Session Messages — Any message sent by the business to customers, within 24 hours of an Incoming Session Message becomes an Outgoing Session Message.

Outgoing Template Messages — If it has been 24 hours since the last Incoming Session Message from the customer, OR if the customer has never messaged the business, then the business can send only an pre-approved Outgoing Template Message.
