# Retry pre-authorization

> Retry a pre-authorization through the dedicated SmartRetry retry operation.

Use this operation to create a new retry attempt for a previous
[pre-authorization](/docs/api-reference/payments/preauth). Identify the originating attempt using one of
the request shapes rendered below.

<Note>
  This operation creates a dedicated retry attempt. It is different from replaying the original
  Pre-authorization request with the same `Idempotency-Key`. See
  [Idempotency](/docs/api-reference/idempotency) for safe request replay.
</Note>
