Deleting custom actions
Custom actions created in default settings can also be deleted. Deleting a custom action in the default settings removes it from the default settings and means the action will no longer be added to newly added servers. Deleting the action in the default settings does not remove it from existing source servers that have it. To delete a custom action from existing servers, go to the Source server details page, select the Post-launch settings tab and delete the action from there. Pre-defined actions cannot be deleted through AWS console. If a pre-defined action is not required, it can be deactivated or deleted via API.
Locate the action you want to delete in the Actions card view, or use the search field to filter the actions by name. Select the action, and click the Delete button. To confirm, press Delete.
