### Overview

Delete a subject type. 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://dnd37xeb23o8n.cloudfront.net/stefon.simmons/docs-astro-web-10435/ja/api/latest/scopes.md#experiments) to access this endpoint.
