Capabilities

Tools 19

resos_add_booking_note

WRITE: add an internal restaurant note to a booking (for example `Birthday, bring a candle`). The guest does not see it and nothing is sent. At most 50 notes per booking; notes cannot be deleted through the API. Not retried: after a timeout read the booking first, or the note may be added twice. POST /bookings/{id}/restaurantNote.

Discovered
resos_cancel_booking

Date and time are in the restaurant's local timezone. Check resos_get_available_times first: resOS may refuse a slot that is full or closed. It is not retried: if the call times out, read the bookings before you try again, or you may book twice. resOS may silently throttle the same e-mail, phone or IP creating more than 10 bookings in 24 hours.

Not retried: after a timeout read the booking first, or the guest may get it twice. POST /bookings/{id}/comment.

Discovered
resos_update_booking
