JSON representation
{ "filter": string, "force": boolean }

Fields

Fields
`filter`	`string` Required. The filter string to specify the events to be deleted with a length limit of 5,000 characters. The eligible fields for filtering are: `eventType`: Double quoted `UserEvent.event_type` string. `eventTime`: in ISO 8601 "zulu" format. `userPseudoId`: Double quoted string. Specifying this will delete all events associated with a visitor. `userId`: Double quoted string. Specifying this will delete all events associated with a user. Examples: Deleting all events in a time range: `eventTime > "2012-04-23T18:25:43.511Z" eventTime < "2012-04-23T18:30:43.511Z"` Deleting specific eventType: `eventType = "search"` Deleting all events for a specific visitor: `userPseudoId = "visitor1024"` Deleting all events inside a DataStore: `*` The filtering fields are assumed to have an implicit AND.
`force`	`boolean` The `force` field is currently not supported. Purge user event requests will permanently delete all purgeable events. Once the development is complete: If `force` is set to false, the method will return the expected purge count without deleting any user events. This field will default to false if not included in the request.
