Combined Booking Links (Collective Availability)

The link format

A combined link is your normal booking URL with more than one handle in it, joined by +:

• calendarbridge.com/book/frank+chad: each person’s default scheduler.
• calendarbridge.com/book/frank_sales+chad_sales: a specific scheduler for each person, written as handle_scheduler.
• calendarbridge.com/book/frank+chad_sales: mix and match; each side is resolved independently.

In other words, take the URL you would normally share, /book/frank/sales, replace the slash with an underscore to get frank_sales, and join it to the next person with +.

Three ways to assign the meeting

By default a combined link is collective: everyone has to be free, and everyone ends up on the meeting. Add one more token at the end of the link to change that:

• calendarbridge.com/book/frank+chad: Everyone together. Only times when every host is free; all of them are invited.
• calendarbridge.com/book/frank+chad+fa: First available. A time is offered if any host is free. The first person in the link who is free at that time takes the booking, and only they are on the meeting.
• calendarbridge.com/book/frank+chad+rr: Round robin. Same availability as first-available, but bookings rotate: whoever has gone longest without one goes next.

The mode token has to be the last thing in the link. fa and rr can never clash with a real handle, since handles are at least five characters, so there is nothing to escape.

Build one from the dashboard

You don’t have to assemble the URL by hand. On the Schedulers page, click Build a combined link in the top-right of the Schedulers card.

1. Pick your scheduler
   Choose which of your own schedulers should drive the link, or leave it on your default one. This scheduler sets the meeting length, booking window, event subject, timezone, branding, and any workflow. The other people only contribute availability.
2. Choose how bookings are assigned
   Pick Everyone together, First available, or Round robin (see above). The builder appends the right token for you.
3. Add your teammates
   Type each teammate’s handle, optionally followed by _ and one of their scheduler names. You can also paste one of their booking URLs and the builder will convert it. Up to five people can share one link.
4. Copy the link
   The finished URL appears at the bottom of the dialog with a Copy button, and an Open button so you can check it before sharing. A combined link works as soon as it exists, and there’s nothing to publish.
5. Save it for next time (optional)
   Give the link a name and click Save. It appears under Saved links in the same dialog, where you can copy it, reopen it in the builder to change who’s on it, or delete it.

Saved links

Because a combined link is just a URL, saving one is purely a bookmark for you: it doesn’t create anything on the server and it doesn’t notify the people on it. Saved links are stored with your personal calendar settings, so they follow your login across devices, and you can keep up to 25 of them.

• Copy puts the full URL on your clipboard.
• Edit loads the link back into the builder so you can swap a teammate or point at a different scheduler, then save over it.
• Delete removes the bookmark. Anyone already holding the URL can still book with it, because deleting a saved link does not disable the link itself.

Saving the same set of people twice updates the existing entry’s name rather than creating a duplicate.

How availability is calculated

An Everyone together link shows the intersection of everyone’s availability. A slot is only offered when all of the following hold:

• The day is switched on in every person’s weekly availability.
• The time is inside the overlap of everyone’s working hours for that day: a 9–5 and a 10–3 produce 10–3.
• Nobody is busy, on their booking calendar or on any “additional calendars to check” they configured.

Everything else (meeting length, buffers, minimum notice, booking window, timezone, custom questions, event color, video conferencing) comes from the first scheduler in the link. That’s the one the booking is written to.

First available and round robin

These two flip the rule: a slot is offered if any host could take it. Availability is worked out separately for each person (their own weekly hours, their own booking calendar, their own “additional calendars to check”) and then combined, so one host being booked solid never hides a time another host has free. A day appears on the calendar as soon as one host works it.

The booking page says “Booking with one of” above the avatars so the booker knows they are getting one person, not the whole group. Meeting length, booking window, questions and branding still come from the first scheduler in the link.

What happens when someone books

Everyone together

• Availability is re-checked for everyone at the moment of booking, so a slot that filled up in the meantime is rejected rather than double-booked.
• The event is created on the first person’s booking calendar.
• Everyone else on the link is added as an attendee, so the meeting lands on their calendars as an invitation: one event, one thread, no duplicates that can drift apart.
• The booker and their guests are invited as usual.
• Reschedule and cancel links work exactly as they do for a single-person link, and update the meeting for everyone at once.
• If the first scheduler has a workflow, its reminders, follow-up, and webhook apply to combined bookings too.

First available and round robin

• Each host’s calendar is checked individually at the moment of booking, and only the hosts who are still free are candidates.
• First available gives it to the first free host in link order. Round robin gives it to the free host who has waited longest since their last booking on this link; someone skipped because they were busy keeps their place at the front of the line rather than losing a turn.
• The meeting is created on that host’s calendar, using their scheduler’s event colour, video conferencing, description and workflow. Nobody else on the link is invited.
• The confirmation screen tells the booker who they got.
• Reschedule and cancel act on the assigned host only. Rescheduling does not re-run the rotation: the meeting stays with the same person.
• Round-robin rotation is shared across the link regardless of the order the handles were typed, so frank+chad+rr and chad+frank+rr take turns from the same queue.

Troubleshooting

• “This booking link is no longer available.” At least one handle in the link doesn’t resolve: a typo, a deleted scheduler, or a scheduler name that was renamed. Rebuild the link from the dashboard.
• No times are offered at all. The working hours probably don’t overlap. If one person works Mon–Fri 9–5 Eastern and another Mon–Fri 9–5 in a distant timezone, the intersection can genuinely be empty. Widen someone’s hours or shorten the meeting length.
• Far fewer times than expected. Buffers and minimum notice from the first scheduler apply to the whole link, and every person’s busy time is subtracted. See Refining Your Scheduler Availability.
• A teammate’s handle has an underscore in it. That still works. CalendarBridge tries the longest possible handle first before treating an underscore as the scheduler separator.
• More than five people. A combined link supports up to five.
• Round robin keeps picking the same person. Only hosts who are actually free at the chosen time are eligible, so if the others are busy at the times bookers tend to pick, one host will naturally get more. Check the busy hosts’ weekly availability and “additional calendars to check”.
• A first-available link shows times one host can’t make. That is by design: the slot is offered because someone is free, and the booking goes to whoever that is.
