FAQ

Questions about Calendly + Slack.

How do I post Calendly bookings into a Slack channel?
Calendly Invitee Created → Slack Send Message to #bookings with an embed-style attachment showing invitee, scheduled time, event type, and link to the booking. One trigger, immediate team awareness.
Can I DM the host with prep notes?
Yes. Look up the host's Slack ID by Calendly email → Slack Send Direct Message with the booking + prep content (intake answers, CRM context). Personal heads-up without channel noise.
How do I route different Calendly event types to different Slack channels?
Switch on event_type slug. Demos → #sales-bookings. Customer-research → #research. Support-calls → #support-bookings. One Calendly trigger, multiple channel destinations.
Can I notify Slack of cancellations too?
Yes. Calendly Invitee Canceled → Slack Send Message with "{Invitee} cancelled their {event_type} for {time}". Useful for time-sensitive bookings (interviews, customer demos) where the host needs to plan a follow-up.
How do I include intake-answer details in the Slack message?
Format the questions_and_answers array as Slack Block Kit fields. Each Q/A pair becomes one field. Caps display nicely; agents see context without clicking through to Calendly.
Can Slack threads collect post-meeting feedback?
Yes. Post the original booking as a parent message; after the meeting, post follow-up messages in the same thread. Or use a slash command (/recap) to add structured recap fields back into the thread.
