ConnectWiz + Apple Calendar
Live integrationApple Calendar: bookings out, busy time in
Appointments made in ConnectWiz appear in Apple Calendar and disappear on cancel — and events already in Apple Calendar subtract from availability, so the AI never offers Thursday 15:00 when your calendar has the dentist there.
Calendars
What it does — precisely
Push, with cleanup
New bookings create events in Apple Calendar; cancellations remove them. The practitioner’s calendar is never a day behind the diary.
Busy time counts
External events subtract from availability before any door — panel, AI, flow or widget — offers a slot. Double-booking against your personal life is blocked too.
Direction is a setting
Per connected source you choose: read from it, write to it, both, or busy-only — so a shared clinic calendar and a personal one can play different roles without a fight.
Under the hood
Sync semantics that don’t double-book you
CalDAV with an app-specific password
Apple’s supported third-party door is CalDAV: you mint an app-specific password in your Apple ID (your real password never leaves Apple), and events read and write against your iCloud calendar collection over the open standard.
Roles are three axes, not one dropdown
Per source you set whether it feeds bookings in (never, one-time import, or continuously), whether bookings mirror out to it, and whether its busy time blocks availability — a shared clinic calendar and a personal one can play entirely different roles.
Fail-closed where it must
A calendar that only blocks availability fails closed on a read error — unknown busy time blocks bookings rather than permitting a collision. A source that feeds the ledger fails open. Getting this line wrong is the single most expensive mistake in calendar sync, so it’s a rule, not a mood.
Self-healing connections
A connection that errors is marked so, with the reason — and the next successful read clears it automatically. An outage that ends doesn’t need a human to come and un-tick anything.
Minimal event payloads
What lands in your calendar is the booking type’s name, the guest’s name and notes, and the times — no attendee invitations, no conference links, no reminder overrides. Your calendar clients stay in charge of their own noise.
Conflicts have a declared policy
When two-way editing lands, every source will already carry a conflict policy — hold for a human (the default, which also pauses reminders), ours wins, or theirs wins, with the losing version kept and shown. Declared before it’s needed, because retrofitting a conflict policy mid-incident is how data disappears.
Setup
How it connects
Connect Apple Calendar
Connect via CalDAV with an app-specific password from your Apple ID.
Assign its role
Read, write, both, or busy-only — per calendar.
Book anywhere
Panel, AI, flow or website widget — every door sees the same subtracted availability.
Better together
What it composes with
The booking engine
Availability, buffers, notice windows and overlap-proof holds live in the booking system — the calendar feeds it truth.
Wiz books safely
The AI agent offers only slots that survive the busy-time subtraction — a database constraint, not a hope, prevents the double-book.
CRM diaries
Running Estesoft Stella? Its diary and your calendar both subtract from the same availability — see the Stella integration.
Security & guarantees
The boring guarantees
Minimal scopes
The connection asks for calendar access only — no mail, no contacts, no drive. Tokens are encrypted at rest and refreshed automatically.
Your events stay yours
Busy-time reads pull times, not contents — availability math needs to know that you’re busy, not why.
Disconnect is clean
Removing a connection stops sync immediately; mirrored events already in your calendar remain yours to keep or clear.
The honest fine print
Boundaries, stated
The ledger stays ours
Whatever calendars connect, the booking ledger remains ConnectWiz’s own table — calendars are mirrors and sources, never the master. That’s a design position, stated.
Reminders are ours, not the calendar’s
Booking reminders send from ConnectWiz — email, and SMS where configured — rather than as calendar notifications, so they reach guests who never opened a calendar invite. Stated, because two reminder systems firing is worse than one.
Connected honestly beats connected loudly.
