# Appointment Opening Offer Stale

> The authority behind the regular opening offer changed

## Cause

The barber, location, services, occurrence, time zone, schedule, booking window, or service terms no longer match the issued offer. The appointment was not created.

## Fix

List openings again, ask the customer to choose from the current regular offers, and create the appointment with the new `offerId`.

## Retry safety

Not retryable until the request carries an offer for the current booking rules.
