Are someone tried to send messages through the facebook messenger? I have a marketplace where every user can put his item to sell. I want to add possibility to send messages from the sellers to the buyers through the facebook messenger.
Right now I have the button to connect to my facebook application. In plugin that I am using there is also an action to send messages through the facebook but it need to be send manually. My target is to send messages automatically (with default text) after fire a specific event.
Thank you in advance
