You need a Calendly paid plan, Standard or above. Calendly refuses bookings and webhooks from other apps on its Free plan. If you connect a Free account, the Calendly card tells you to upgrade.
Know the limits before you connect
Calendly sets these limits on bookings from other apps:- Booking cap: below Enterprise, each Calendly user gets 10 bookings a minute, 50 an hour and 100 a day. A trial gets 5 a day.
- Moves: Calendly has no way for an app to reschedule. LobbyStack books the new time, then cancels the old one, so a move counts as one booking.
- Length: every booking takes the event type’s default length.
What Calendly receives
For each appointment, Calendly receives:- Invitee name: the caller’s, so you see who booked
- Invitee email: a stand-in address unique to the appointment, so Calendly doesn’t email the caller
- Answers to the event type’s questions: the caller’s name, phone number and real email go in a text question, so you can reach them

A link from
POST /calendars/calendly/connect works only for an owner or admin of the business. For a business with neither, the API answers 409, so invite one with POST /team/invitations first.Set up the event type in Calendly
After you pick an event type, the dialog lists anything to fix in Calendly:- Required choice questions: make them optional. Your AI agent can’t answer a required single-select or multiple-select question, so you can’t pick an event type that has one.
- Text question: add one to the event type. Without it, your team can’t see the caller’s phone number or email in Calendly.
- Duration: set the event type to the length of your services. Calendly books every appointment at that length.
- Location: add a phone or in-person location. Otherwise bookings carry a video link.
Use Calendly with Google Calendar or Cal.com
Busy time on every connected calendar blocks bookings. New appointments go to Calendly or Cal.com over Google Calendar, because their booking pages take bookings on their own. A team member’s own calendar still comes first for their appointments.Change the event type
- Open Business > Integrations.
- Click the Calendly card.
- Choose another event type.
