Does it know whether the meeting actually happened?
No, and nothing could. Calendly records that a booking was made and, where relevant, that it was cancelled; whether the person turned up is knowledge only your team has. That is why the useful setup adds an outcome field that somebody fills in. It is one column, and it is the difference between counting bookings and counting meetings.
Can it cancel or reschedule a booking?
No. The connection reads and never writes, so nothing done here changes a Calendly booking and no automation can. Rescheduling stays with Calendly and with the invitee, which is the correct place for it — the link in their confirmation email is the thing they already have, and a second way to move a meeting is a good way to have two records disagree.
How current is the table?
As current as the last import, because this pulls rather than listens. Importing again updates the same table, matched on each Calendly booking, and Keep in sync does that hourly or daily; the outcomes your team fills in live in a column the import never touches, so they stay put. The invitee's name and email are looked up once, when a booking first arrives. If you want a booking to trigger something within seconds of being made, that is a different mechanism from an import.
What if the same person books repeatedly?
Each booking is its own row, which is what you want: three calls with one customer are three meetings, not one. Linking by invitee email gives you both readings at once, since the contact record then shows every booking against it while the events table still counts each one separately. Totalling per contact is a rollup rather than a de-duplication problem.
Does this replace RowFold's own booking pages?
No, and they solve different problems. A RowFold booking page writes the appointment straight into a table you own, checks your team's real calendars for conflicts and can take a deposit. This connector is for teams already committed to Calendly who want the resulting meetings somewhere they can be counted. If you have not chosen yet, the booking pages are the shorter path.
