How do I add a chat channel?

1. In the chat app, make an incoming webhook for the channel and copy its address:
   • Slack: add the Incoming Webhooks app to the channel and copy its webhook URL. It starts with https://hooks.slack.com/services/.
   • Microsoft Teams: open the channel's Workflows, choose "Post to a channel when a webhook request is received", and copy the address it gives you.
   • Google Chat: open the space's Apps and integrations, add a webhook, and copy its address. It starts with https://chat.googleapis.com/.
2. In Masthead, open Settings → Company → Chat alerts (admins, leadership and HR).
3. Under Add a channel, choose Where (Slack, Microsoft Teams or Google Chat), give it a Name, such as #people-team, and paste the Webhook address.
4. Tick the alerts it should get, and click Add channel.
5. On the channel's card, click Send a test message and look for it in the channel.

Keep the address private: anyone with it can post to the channel. Masthead keeps it encrypted and shows only its end.
