# Off-Hours Quote Already Used

> The off-hours quote was already redeemed by another request

## Cause

The quote was already redeemed with a different idempotency key. An off-hours quote has one successful redemption. The appointment was not created again.

## Fix

If the original result is unknown, retry the original idempotency key. To make a different booking attempt, list openings again and use a new quote.

## Retry safety

Not retryable until the underlying state or request changes.
