FAQ

Questions about Slack + Google Calendar.

How do I post upcoming Calendar events to Slack?
Scheduled 9am daily: List Events for today → format as bullet list → Slack Send Message to your DM or a team channel. Single morning checkpoint instead of constantly checking calendar.
Can I get a Slack DM 15 minutes before each meeting?
Yes. Calendar Event Starting Soon → Slack Send DM to the organizer with meeting details + join URL. Reduces "I forgot" meetings.
How do I post Calendar event changes to the team?
Calendar Event Updated → Slack Send Message in a team channel with what changed (time, attendees, location). Useful when shared team meetings move and not everyone reads calendar notifications.
Can Slack reactions update Calendar event responses?
Yes. Slack message with RSVP buttons → button click trigger → Calendar Update Event response (accept/decline). Useful for team-meeting RSVPs without leaving Slack.
How do I set Slack status when a Calendar meeting starts?
Calendar Event Starting → Slack Set Status with emoji "🤝 In a meeting" and expire timer matching event end. Auto-clears on meeting end. Reduces interruption pings.
Can I avoid Slack noise for back-to-back meetings?
Aggregate. Replace per-meeting pings with a single morning digest. Or only ping for meetings with external attendees (when prep actually matters).
