## Common Errors

### 401 Unauthorized

**Cause:** Missing or invalid API key

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Invalid API key",
  "code": "INVALID_API_KEY"
}
```

**Solution:** Verify your API key is valid and active.

### 403 Forbidden

**Cause:** The facility does not belong to your organization

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Facility doesn't belong to organization",
  "code": "FACILITY_NOT_BELONG_TO_ORGANIZATION"
}
```

**Solution:** Verify the `facility_id` belongs to your organization using the [Facilities API](/api-reference/facilities/list).

### 422 Validation Error

**Cause:** Missing required `facility_id` or invalid query parameter values

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["query", "facility_id"],
      "msg": "field required",
      "type": "value_error.missing"
    }
  ]
}
```

**Solution:** Ensure `facility_id` is provided and all filter values are valid.
