# /v3/confirmations/{token}/lock

> Consume a pass so it reads as not passed everywhere.

`POST` Secret key. Idempotent. Applies to the person's pass on this verification, not just the token.

Use it for one pass per human, ever. For double-submit protection use your own idempotency on the token. For once-per-period caps configure a limit on the verification.

## Path parameter

<ParamField path="token" type="string" required>The `vyt` for the pass to lock.</ParamField>

## Response

Same shape as [`GET /v3/confirmations/{token}`](/v3/dev/spec/server-api/confirmations); after locking, `verified` is `false`.

## Errors

| ------ | --------------- | ---------------------------------------------------------- |
| `404`  | `token_invalid` | Not ours, not yours, wrong partition, or the pass is gone. |
| `410`  | `token_expired` | Older than 30 minutes.                                     |
