# Epic Links API[](#epic-links-api-ultimate "Permalink")

**注意：**该端点是在 GitLab 11.8 中[引入的](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/9188) .

管理亲子[史诗般的关系](../user/group/epics/index.html#multi-level-child-epics-ultimate) .

每个对`epic_links` API 调用`epic_links`必须经过身份验证.

如果用户不是组的成员，并且该组是私有的，则对该组的`GET`请求将导致`404`状态代码.

多级史诗仅在 GitLab [Ultimate / Gold](https://about.gitlab.com/pricing/)中可用. 如果"多级史诗"功能不可用，将返回`403`状态代码.

## List epics related to a given epic[](#list-epics-related-to-a-given-epic "Permalink")

获取史诗的所有子史诗.

## Assign a child epic[](#assign-a-child-epic "Permalink")

在两个史诗之间创建关联，将一个史诗指定为父史诗，将另一个史诗指定为子史诗. 父史诗可以有多个子史诗. 如果新的子史诗已经属于另一个史诗，则该子史诗不会从先前的父史诗中分配.
