# not_found

> The not_found error from the Warmerly API (HTTP 404): The resource doesn't exist, or doesn't belong to you.

Source: https://warmerly.com/docs/errors/not-found

The API returns `not_found` with HTTP status **404**.

The resource doesn't exist, or doesn't belong to you.

## Where the API reference mentions it

- [Steps (Campaigns)](https://warmerly.com/docs/campaigns/steps)

## What the response looks like

```json
{
  "error": {
    "code": "not_found",
    "message": "...",
    "details": null
  }
}
```

`error.code` is stable and safe to branch on. `error.message` is debugging context, not something to parse. The full list of codes, and the rate limits, are on [Errors & Rate Limits](https://warmerly.com/docs/errors).
