Your appointment link lets you do four things: book a time, reschedule it, change your details, or cancel it — all without an account or a password. Every one of those sends you a confirmation email, and each of those emails carries the links you need to make the next change.

Open the appointment link you were sent. It opens on a month calendar showing when the person you are booking with is available.

Only the highlighted dates have availability — the rest cannot be selected, so you cannot accidentally pick a day that will not work.

On some schedules each time shows how many places are left — for example Available: 3. That means several people can book the same window, so you are choosing a period rather than a private slot.

The date and time you picked stays visible on the left while you type, so you can check it before confirming. Which fields you are asked for varies — whoever set the schedule up chooses whether to ask for a unit number, whether you own or rent, and site access notes.

You get a confirmation email straight away, headed New Booking. Keep it: it contains the links to reschedule, update or cancel this booking. The person the appointment is assigned to is notified at the same time.

If you lose the email, ask whoever sent you the original booking link — the links are unique to your booking and cannot be looked up from the booking page.

Select Reschedule in your confirmation email. The page shows your current appointment beside the new one you are choosing, so you can see exactly what is changing before you commit.

Pick the new date and time, check your details are still right, then select Reschedule Booking. You will get a Booking Rescheduled email confirming the new time.

Select Update in your confirmation email. This changes your details — name, phone, unit number, site access notes — while keeping the same appointment time. You will get a Booking Updated email.

Use Reschedule instead if you want a different time. Update will not move the appointment.

Select Cancel in your confirmation email. Your booking details are shown read-only so you can check you are cancelling the right one.

Select Cancel Booking to confirm. You will get a Booking Cancelled email, and the person you were booked with is told as well. Cancelling cannot be undone — to come back later, book a new appointment from the original link.

Every one of these also goes to the person your appointment is with, so you do not need to tell them separately.

Check your spam or junk folder first — the email comes from a do not reply address, which some filters treat as promotional. If it is not there, the address may have been mistyped when booking. Contact whoever sent you the booking link; they can see the booking and correct it.

No. It is sent from an unmonitored address. Use the Reschedule, Update or Cancel links in the email, or contact the company directly.

Dates without availability cannot be selected. That means the schedule does not run that day, the day is outside its date range, or every slot is taken. Try a highlighted date, or move to the next month using the arrows above the calendar.

That depends on how the schedule was set up — some allow multiple bookings from the same person and some do not. If a second booking is refused, that schedule allows one per person.

No. The booking link works without signing in, and so do the reschedule, update and cancel links.

Times are shown in the schedule's timezone, named on the left of the booking page — for example W. Australia Standard Time. The current time in that timezone is shown underneath, so you can check it against your own.
