What is 24 Hours Window in Chat
WhatsApp provides a 24 hour customer service window during which you can exchange any number of free flowing messages with the customer. This 24 hour window is calculated from the time your customer last messaged you. Beyond the 24hours, you can only send template messages to the customer. The 24hour window will open up again ONLY once the customer responds to you. Till the customer responds, you can only send template messages.
Here’s an article on Templates that can help rekindle chats after the the 24hour window.
Note: This is WhatsApp’s policy and hence Zoko has no control over it.
