# Update comment settings

`PATCH https://api.cademi.com.br/api/v3/settings/support/comments`

Operation ID: `settings.support.comments.update` · API v3

Updates the lesson comment settings. Only the fields included in the request are changed; omitted fields are left unchanged.

Setting `moderation_enabled` to `false` publishes every comment in the account that is pending moderation. The number of comments published is returned in `effects.approved_pending_comments`.

To avoid overwriting a newer version, send the `ETag` returned by the retrieve operation in the `If-Match` header. The header is optional; when it is omitted, the update is applied to the current revision.

Required permissions: `settings.update_support`.

## Parameters

| Name | In | Type | Required | Description |
