# Invalid Off-Hours Quote

> The off-hours quote failed tamper validation

## Cause

The supplied quote identifier has a valid wire shape, but its tamper-evident validation failed. The appointment was not created.

## Fix

Discard the quote, list openings again, and retry with an unmodified `quoteId` from the new response.

## Retry safety

Not retryable until the underlying state or request changes.

## Raised by
