Instant Book decides whether a shift someone reserves is confirmed straight away or has to be approved by an admin first.
It is a per opportunity setting, so you can run some opportunities open and keep others gated.
Only people already approved or assigned to that opportunity.
Instant Book does not open your shifts to the public or to anyone who has not been through your recruitment process. It only changes what happens after that point, which is the part most often misread.
Every reservation lands in your Shift requests queue for approval.
Two consequences worth knowing before you turn it off:
If your recruitment workflow lets people choose shifts while they register, Instant Book decides how much of that sticks:
This is why Vome recommends pairing an auto-approve form action with Instant Book. Auto-approving someone into an opportunity and then making them wait on every shift is a half-open door, and it tends to surprise both sides.
When who is on a given shift genuinely matters, and a wrong booking is expensive to unpick. Typical cases are shifts with a hard skill requirement, work with vulnerable clients, or a tightly capped site.
For general help, events and anything where an extra pair of hands is welcome, leaving it on saves your coordinators the queue entirely.
On the opportunity itself. When it is already on you will see Instant Book enabled, which you tap to disable, and Vome confirms the change.
You can change it at any time. It applies to reservations made from then on, so turning it off does not retract shifts already confirmed.
