{{< /details >}}

[Push mirrors](../user/project/repository/mirror/push.md)
defined on a project's repository settings are called remote mirrors. You
can query and modify the state of these mirrors with the remote mirror API.

For security reasons, the `url` attribute in the API response is always scrubbed of username
and password information.

{{< alert type="note" >}}

[Pull mirrors](../user/project/repository/mirror/pull.md) use
[a different API endpoint](project_pull_mirroring.md#configure-pull-mirroring-for-a-project) to
display and update them.
