# Application settings API **(FREE SELF)**

These API calls allow you to read and modify GitLab instance
[application settings](#list-of-settings-that-can-be-accessed-via-api-calls)
as they appear in `/admin/application_settings/general`. You must be an
administrator to perform this action.

Application settings are subject to caching and may not immediately take effect.
By default, GitLab caches application settings for 60 seconds.
For information on how to control the application settings cache for an instance, see [Application cache interval](../administration/application_settings_cache.md).

## Get current application settings

## List of settings that can be accessed via API calls

> - Fields `housekeeping_full_repack_period`, `housekeeping_gc_period`, and `housekeeping_incremental_repack_period` [deprecated](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/106963) in GitLab 15.8. Use `housekeeping_optimize_repository_period` instead.
> - Parameters `sign_in_text` and `help_text` were [deprecated](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/124461) in GitLab 16.2. Use `description` parameter in the [Appearance API](../api/appearance.md) instead.
> - Parameter `allow_account_deletion` [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/412411) in GitLab 16.1.

In general, all settings are optional. Certain settings though, if enabled,
require other settings to be set to function properly. These requirements are
listed in the descriptions of the relevant settings.

## Housekeeping fields

::Tabs

:::TabTitle 15.8 and later

If the `housekeeping_optimize_repository_period`
field is set to an integer, housekeeping operations are performed after the number
of Git pushes you specify.

:::TabTitle 15.7 and earlier

The `housekeeping_enabled` field enables or disables
Git housekeeping. To function properly, this field requires `housekeeping_optimize_repository_period`
to be set, or _all_ of these values to be set:

- `housekeeping_bitmaps_enabled`
- `housekeeping_full_repack_period`
- `housekeeping_gc_period`
