### Overview

Delete a non-decision metric group and its memberships. Decision groups remain managed through the experiment resource. This operation does not start a pipeline. Read experiment results after deletion to check stale metadata, then explicitly refresh results when required.

This endpoint requires the `product_analytics_experiments_write` permission.

OAuth apps require the `product_analytics_experiments_write` authorization [scope](https://dnd37xeb23o8n.cloudfront.net/jen.gilbert/astro-base/ja/api/latest/scopes.md#experiments) to access this endpoint.
