Autoresponder for Google Hangouts
Supported Google Products
Autoresponses are only guaranteed to work for direct messages where both the sender and receiver are using Google Hangouts. Even though other kinds of messages are visible in Google Hangouts, they're not sent over the only public api (which was originally developed for Google Talk).
Here are the common kinds of messages that will not trigger an autoresponse:
- Hangouts group messages, except for the initial invitation
- Google Voice SMS messages
- Google Chat direct messages
