Send group iMessage using applescript

Question

Does anyone know how to send a group message using applescript/osascript? I've tried a bunch of stuff but nothing seems to work.

Answer 1

If you take a look into the iMessages (former iChat) dictionary you see that you only can send messages to a buddy or a text chat . There is no "group" available. BUT, if you have a group, say a list of people, you can compare this to available buddies and send to each one of them, like suggested in this post .

Answer 2

@turingtested's response above led me to a solution that solved this problem for me, provided that there's an already-existing named chat.

In AppleScript's documentation, send can send to a chat :

A chat has a name property that is how the chat's name appears in the chat list:

I then went into Messages, created the desired group and added a group name. Once you've done that, the following code will do the trick:

tell application "Messages"
    send "Your message here" to chat "group name"
end tell
