title: "Add Auto Moderation custom_message Action Metadata Field"

Add new `custom_message` [action metadata](/docs/resources/auto-moderation#auto-moderation-action-object-action-metadata) for the `BLOCK_MESSAGE` [action type](/docs/resources/auto-moderation#auto-moderation-action-object-action-types)). You can now specify a custom string for every Auto Moderation rule that will be shown to members whenever the rule blocks their message. This can be used as an additional explanation for why a message was blocked and as a chance to help members understand your server's rules and guidelines.
