The record is soft-deleted and stops appearing in reads. The call is idempotent: deleting the same subject type again also returns 204. The organization's default subject type cannot be deleted; make another one the default first. A subject type that experiments, exposure SQL models, metric SQL models or protocols still reference cannot be deleted either; the refusal names the blockers. This endpoint requires the `product_analytics_settings_write` permission. OAuth apps require the `product_analytics_settings_write` authorization [scope](https://docs.datadoghq.com/api/latest/scopes.md#experiments) to access this endpoint. ### Arguments #### Path Parameters
