# User Value

**Example**

```json
{
    "email": "john@dow.com",
    "id": "ca4be988-cc85-4c35-94a4-8558e30c1dd3",
    "image": null,
    "isBot": false,
    "name": "John"
}
```

Identify a user using `email`, user `id`, or `customIdentifier`. At least one of `id`, `email`, or `customIdentifier` must be provided for non-bot authors.

`customIdentifier` - the value is normalized (trimmed and stored in lowercase), so responses may return it in a different case than provided in the request.

If the author is a bot, set the `isBot` property to `true`.

**Identifier precedence:** when multiple identifiers are provided, the system resolves the user in the following order: `id` > `email` > `customIdentifier`. If a user is found by a higher-priority identifier, the remaining ones are ignored for lookup purposes. If both `email` and `customIdentifier` are provided and the user is found by email, the `customIdentifier` will be attached to that user if not already set.
