How do I change, pause or remove a chat channel?

On the channel's card in Settings → Company → Chat alerts:

• Edit changes its name, its alerts or its address (paste a new one under New webhook address, or leave it empty to keep the one saved). Untick Post alerts to this channel to pause it; the card then says Paused.
• Send a test message checks it still works.
• Remove stops alerts going to it.

If a post fails, the card says why, after Last post failed. Check the address, or make a new webhook in the chat app and paste it in, then send a test message.

A channel gets at most six posts a minute; any more go together as one message, so the channel isn't flooded. A company can have up to 20 channels. If the add-on ends, your channels stay saved, and nothing is posted until you add it again.
