### Overview

Update a non-decision metric group. Omitted attributes are unchanged; a supplied metrics array is the complete ordered replacement. Decision groups remain managed through the experiment resource. This operation does not synchronously recompute results.

This endpoint requires the `product_analytics_experiments_write` permission.

OAuth apps require the `product_analytics_experiments_write` authorization [scope](https://dnd37xeb23o8n.cloudfront.net/stefon.simmons/docs-astro-web-10435/ja/api/latest/scopes.md#experiments) to access this endpoint.

### Arguments

| ---------------------------- | ------ | ----------------------------- |
| experiment_id [*required*]   | string | The UUID of the experiment.   |
| metric_group_id [*required*] | string | The UUID of the metric group. |
