GitLab 如何通过 WebHook 获取单次 Push 的所有 Commit (超过 20 条)?

如题，需要对所有的代码 commit 进行规范审查，但是 WebHook 有限制：

Note: When more than 20 commits are pushed at once, the commits web hoo attribute will only contain the first 20 for performance reasons. Loading detailed commit data is expensive. Note that despite only 20 commits being present in the commits attribute, the total_commits_count attribute will contain the actual total.

有用过这个接口的老哥吗？讨教一下经验，怎么处理这种情况。
