# Appointment Opening Offer Expired

> The regular opening offer expired before appointment creation

## Cause

The offer passed its published `expiresAt` time before appointment creation. The appointment was not created even if the time is still available.

## Fix

List openings again, ask the customer to confirm the current regular opening, and create the appointment with its new `offerId`.

## Retry safety

Not retryable until the request carries a current opening offer.

## Raised by

This operation can return this problem:

* [Create an appointment](/api-reference/appointments/create-an-appointment)
