delete
https://api.split.io/internal/api/v2/schema/ws//trafficTypes//
Delete an attribute schema by its traffic type and attribute ID. This removes any stored data for that attribute from all Identities (keys) in the Split application. The change to Identity keys is processed asynchronously for traffic types with many Identities it may take up to a minute. However, the Attribute delete occurs synchronously, and if the http call returns as a success (2XX), then the attribute is successfully deleted.
