Any good plugin to use whatsapp?

Im looking for a plugin that will allow me to send whatsapp message to a contact that is not currently on my contact list
any one knows about such a plugin?

I’ve check this plugin :
But its working only if i have already have this contact in my contacts

And why don’t you add the contact and then send the message?

the idea im having is for users to chat with people they don’t know,
so i was hoping to avoid this
but are you reffering to use this
prior and then use the whatsapp plugin?

That’s exactly what I thought.
