# `/sys/wrapping/unwrap`

The `/sys/wrapping/unwrap` endpoint unwraps a wrapped response.

## Wrapping Unwrap

This endpoint returns the original response inside the given wrapping token.
Unlike simply reading `cubbyhole/response` (which is deprecated), this endpoint
provides additional validation checks on the token, returns the original value
on the wire rather than a JSON string representation of it, and ensures that the
response is properly audit-logged.

This endpoint can be used by using a wrapping token as the client token in the
API call, in which case the `token` parameter is not required; or, a different
token with permissions to access this endpoint can make the call and pass in the
wrapping token in the `token` parameter. Do _not_ use the wrapping token in both
locations; this will cause the wrapping token to be revoked but the value to be
unable to be looked up, as it will basically be a double-use of the token!

| Method | Path                   |
| :----- | :--------------------- |
| `POST` | `/sys/wrapping/unwrap` |

### Parameters

- `token` `(string: "")` – Specifies the wrapping token ID. This is required if
  the client token is not the wrapping token. Do not use the wrapping token in
  both locations.
