# api_key_roll_conflict (/en/docs/errores/api_key_roll_conflict)

This key was rolled concurrently; this roll did not land.

| -------------- | --------------------------------- |
| **Code**       | `api_key_roll_conflict`           |
| **Type**       | `conflict_error` — State conflict |
| **HTTP**       | `409`                             |
| **Retriable?** | **Yes**                           |

## What to do [#what-to-do]

Another roll of the same key won the race, and ITS secret is the live one — the response you are reading carries none. Fetch the key again and roll once if you still need to.

> **Note**
>
> Retrying the same request may work. Respect `Retry-After` when it comes.

## The envelope [#the-envelope]

```json
{
  "error": {
    "type": "conflict_error",
    "code": "api_key_roll_conflict",
    "message": "…",
    "hint": "Another roll of the same key won the race, and ITS secret is the live one — the response you are reading carries none. Fetch the key again and roll once if you still need to.",
    "retriable": true,
    "doc_url": "https://docs.facturia.cl/errors/api_key_roll_conflict",
    "request_id": "req_01K2R7Q9M4T2VB"
  }
}
```

Program against `code`, never against `message` — the prose can be rewritten, the code cannot (§5.8).

`hint` and `retriable` arrive in the response with these exact values: they are a function of `code` and come from the same dictionary `GET /v1/error_codes` serves, so the envelope and the dictionary cannot disagree. Both are English on the wire by design — one registry, one language. More in [The error envelope](/en/docs/errores).
