Modify how user custom properties are considered by Kevel Forecast by associating a forecast type. Currently, the only type of user custom properties that can be defined is "static".
Typically, Kevel Forecast considers the value of each user custom property as it existed at the time of the historical Ad Request. Setting a user custom property as static will cause Kevel Forecast to consider its value as the result of the ingested files. These properties can be targeted by custom targeting rules (Zerkel query) such as $user.custom.<static_property> = 1 (head to Custom Targeting for more details).
Note that this endpoint fully replaces the existing set, so to remove all types association send an empty JSON object. See Static Audiences for more details on this feature.
