The booking keeps its id. The response is the moved booking.
The new time must be an open slot. Read the open slots from
GET /v1/availability. Pass the id of this booking as
exclude_booking_id. If you do not, the slot that the booking holds
now counts as busy.
A booking that is not confirmed cannot move.

Section titled “ Request Body required ”object
An RFC3339 timestamp. The new start time.
Moves the booking to this calendar. If it is absent, the booking keeps its calendar.

{ "starts_at": "2026-09-02T14:00:00+01:00"}Responses
Section titled “ Responses ”The moved booking, with the same id.
object
When the booking last changed. Send it back as updated_since on
GET /v1/bookings to read everything that changed after it.
The customer’s manage link token. It is present only on the response that creates the booking. Store it then. No later response repeats it.
When this booking stops holding its slot. It is present only while the booking is on a hold, and absent otherwise.
Show this time rather than counting a fixed number of minutes from now. The window differs between a booking waiting on a code and one waiting on a card, and it is longer for a card because a 3DS redirect goes to the customer’s bank and back.
Present only when the service takes a payment, and only on the response that creates the booking. The key is absent for a service that takes no payment. It is never null, so a client can test for the key itself.
Use these fields to mount Stripe’s Payment Element on the connected account and confirm the payment. The client secret works once, for this booking.
object
What this booking costs, in the smallest unit of the currency. It is a snapshot taken when the booking was made. Changing the service’s price later never changes it.
The business’s Stripe account. Pass it as stripeAccount when you
construct Stripe.js.
The Stripe publishable key to construct Stripe.js with. It is not
your Keptslot pk_ key.
The extras booked with the service, in the order the business lists them. Empty when there are none.
One extra on a booking, as it was when the booking was made. A later change to the service does not change it.
object
The price of the whole visit when it was booked: the service plus every extra. It is null when none of them had a price.
The price of the service alone when it was booked, without its extras. It is null when the service had no price.
The record sent with POST /v1/bookings. It is {} when none was
sent, never null.
