Description
These parameters and the possible property values for the respective dashboard widget field objects allow to configure the Top triggers widget in dashboard.create and dashboard.update methods.
Widget fields properties are not validated during the creation or update of a dashboard. This allows users to modify built-in widgets and create custom widgets, but also introduces the risk of creating or updating widgets incorrectly. To ensure the successful creation or update of the Top triggers widget, please refer to the parameter behavior outlined in the tables below.
