# DevOps Research and Assessment (DORA) key metrics API **(ULTIMATE)**
|
|
|
|
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/279039) in GitLab 13.10.
|
|
> - The legacy key/value pair `{ "<date>" => "<value>" }` was removed from the payload in GitLab 14.0.
|
|
> `time_to_restore_service` metric was introduced in GitLab 14.9.
|
|
|
|
All methods require at least the Reporter role.
