# ErrorMessage.Details

A single error detail entry describing one part of a failed change history request.

```
object ErrorMessage.Details
```

## Discussion

Each entry in `ErrorMessage`’s `details` array narrows down which part of the request caused the failure. Use these entries, together with the top-level `message`, for diagnostic logging or user-facing error displays. Use the top-level `code` on [`ErrorMessage`](/documentation/Apple-Ads-Platform-API/ErrorMessage) for programmatic error handling.

### Example

```json
{
  "code": "MISSING_FIELD",
  "message": "eventTime must be provided.",
  "info": {
    "field": "eventTime"
  }
}
```

[`object ErrorMessage.Details.Info`](/documentation/Apple-Ads-Platform-API/ErrorMessage/Details-data.dictionary/Info-data.dictionary)
