# Google Chat

> Direct messages, app mentions, and optional unmentioned space messages.

Google Chat is available only for organizations enabled by Serval. Message the
Serval app directly, or mention it in a space. Direct messages do not require
the optional space subscription described below. Google's ordinary app message
triggers include DMs and app mentions. [Google message triggers](https://developers.google.com/workspace/add-ons/chat/build)

## Unmentioned space messages

An additional connection can deliver messages in a named, threaded space without
an app mention. It requires Serval operator setup, Google Workspace administrator
authorization, and a separate opt-in for each connected space. Availability does
not mean a space is receiving messages; check its delivery status.

In the Google Chat app's help-desk settings, open **Unmentioned messages** on the
connected space, then enable **Receive unmentioned space messages**. The selected
response mode still applies. **On demand** requires a mention to start a request;
a permitted unmentioned reply can continue its existing ticket. Until delivery
is active, mention Serval in each space reply. DMs continue through their existing
connection and do not receive space subscriptions.

Turning the setting off stops that connection's intake immediately; Google-side
cleanup can finish afterward. Disconnecting or removing and re-adding the app
requires a fresh space opt-in. Another team's existing opt-in to the same space
is preserved.

Serval manages the Google app and Cloud infrastructure for the hosted deployment.
Customers authorize the app in Workspace; this setup does not ask them to buy a
Google add-on or attach their own Cloud billing account. Workspace Events requires
a billed Cloud project, and Pub/Sub usage can incur infrastructure charges. This
page does not define Serval commercial pricing or promise free delivery.
