# Payload Object

Alert `payload` is a loosely structured metadata associated with a particular Alert. You will find that information presented in this field significantly varies depending on the Alert's `dataset`, `class.code` and `resource.type`. It means that when working with `payload` object, you must implement conditional handling of fields, as they might be missing or have an unexpected value type.
