# Re-identify redacted values.

`POST /api/reidentify`

Reverses one or more values that were redacted via the CRYPTO_REPLACE or FPE_ENCRYPT_REPLACE strategy. The caller must supply a stated reason, which is recorded in the audit log alongside the actor, timestamp, and count of reversals. A user may re-identify their own values; an admin may re-identify any user's values by supplying that user's email via the owner parameter. CRYPTO_REPLACE requires policyName so the key can be resolved from the stored policy. FPE_ENCRYPT_REPLACE uses the user's per-account FPE key; if the policy specified a custom FPE key, also pass policyName so that key is used instead. Requires the `reidentify` scope.
