# Resource state events API **(FREE)**

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/35210/) in GitLab 13.2.

Resource state events keep track of what happens to GitLab [issues](../user/project/issues/index.md)
[merge requests](../user/project/merge_requests/index.md) and [epics starting with GitLab 15.4](../user/group/epics/index.md)

Use them to track which state was set, who did it, and when it happened.
