How Slotghost fills a cancelled slot
Slotghost checks that a cancelled time is still free, offers it to people whose availability fits, and books the first to claim. Everyone else keeps their place.

One email, the time in their own timezone, and one button. If someone else claims it first, they are told and keep their place. They never make an account.

Questions
Plans, order and what happens when a slot is gone.
Which Calendly plans does it work with?
All of them, Free included. Calendly opened its booking and cancellation API to every plan on 3 November 2026.
Who on the waitlist gets the offer first?
Offers go out in the order people joined, three at a time unless you change it. Only you can move someone to the front.
What if Calendly says the slot is gone?
Then nobody is offered it. Slotghost asks Calendly before every offer and again when booking, so your buffers and other calendars count.
Can health care providers use Slotghost?
Coaches, tutors, trainers and wellness practitioners can. Providers bound by HIPAA cannot: Calendly signs no BAA, so bookings there must hold no protected health information.
Is Slotghost made by Calendly?
No. Slotghost is independent and connects through Calendly’s official API.
