# Revoke key

`DELETE /keys/{key_id}`

Revoke a credential immediately.

**Permission:** Cluster key, or a namespace key managing collection keys within its namespace.

[API key types and authentication](/engine/reference/authentication.md).

Successful revocation returns 204 with no body. Future requests with the revoked secret fail authentication.

## Example request

```http
DELETE /keys/key_01K6Q6N7D8E9F0G1H2J3K4M5N6 HTTP/1.1
Host: engine.example.com
Authorization: Bearer <GRAPHON_ENGINE_API_KEY>
```

## Path parameters

### `key_id`

**string · required**

Administrative key ID with the key_ prefix. Use the ID returned by create or list, not the secret.

## Responses

### 204 · Key revoked

Revocation completed. This response has no body.

#### Response headers

##### `x-request-id`

**string · required**

Request correlation ID. Retain it when investigating a failed or unexpected request.

No response body.

## Errors

[Error format and retry guidance](/engine/reference/errors.md).

### 400 · `invalid_request`

A field, path, parameter, or conditional request rule is invalid.

Correct the request. Unknown fields are rejected.

```json
{
  "error": {
    "code": "invalid_request",
    "message": "A field, path, parameter, or conditional request rule is invalid.",
    "request_id": "req_example",
    "retryable": false,
    "details": {}
  }
}
```

### 401 · `unauthenticated`

The API key is missing, invalid, or revoked.

Send an active key in Authorization: Bearer or X-API-Key.

```json
{
  "error": {
    "code": "unauthenticated",
    "message": "The API key is missing, invalid, or revoked.",
    "request_id": "req_example",
    "retryable": false,
    "details": {}
  }
}
```

### 403 · `forbidden`

The key can see the resource but lacks permission for this operation.

Use a key with the required action or scope kind.

```json
{
  "error": {
    "code": "forbidden",
    "message": "The key can see the resource but lacks permission for this operation.",
    "request_id": "req_example",
    "retryable": false,
    "details": {}
  }
}
```

### 404 · `not_found`

The resource is absent, deleted, or outside this key’s scope.

Check the identifier and the key’s namespace and collection scope.

```json
{
  "error": {
    "code": "not_found",
    "message": "The resource is absent, deleted, or outside this key’s scope.",
    "request_id": "req_example",
    "retryable": false,
    "details": {}
  }
}
```

### 503 · `temporarily_unavailable`

A dependency, cluster readiness condition, or capacity limit prevents this operation.

Inspect retryable and details. Retry only when permitted, preserving the idempotency key for the same write.

```json
{
  "error": {
    "code": "temporarily_unavailable",
    "message": "A dependency, cluster readiness condition, or capacity limit prevents this operation.",
    "request_id": "req_example",
    "retryable": true,
    "details": {}
  }
}
```

### 500 · `internal_error`

An unexpected server failure prevented this request from completing.

Retain x-request-id for investigation. Follow retryable before retrying a write.

```json
{
  "error": {
    "code": "internal_error",
    "message": "An unexpected server failure prevented this request from completing.",
    "request_id": "req_example",
    "retryable": false,
    "details": {}
  }
}
```
