+# Settings updates at runtime
+
+> **Note:** Available in Grafana Enterprise v8.0+.
+
+Settings updates at runtime allows you to update Grafana settings with no need to restart the Grafana server.
+
+Updates that happen at runtime are stored in the database and override
+[settings from the other sources](https://grafana.com/docs/grafana/latest/administration/configuration/)
+(arguments, environment variables, settings file, etc). Therefore, every time a specific setting key is removed at runtime,
+the value used for that key is the inherited one from the other sources in the reverse order of precedence 
+(`arguments > environment variables > settings file`), being the application default the value used when no one provided
+through one of these, at least.
+
+Currently, **it only supports updates on the `auth.saml` section.** 
+
+## Update settings via the API
+
+You can update settings through the [Admin API]({{< relref "../http_api/admin.md#update-settings" >}}).
+
+When you submit a settings update via API, Grafana verifies if the given settings updates are allowed and valid. If they are, then Grafana stores the settings in the database and reloads
+Grafana services with no need to restart the instance.
+
+So, the payload of a `PUT` request to the update settings endpoint (`/api/admin/settings`) 
+should contain (either one or both):
+- An `updates` map with a key, and a value per section you want to set.
+- A `removals` list with keys per section you want to unset.
+
+For example, if you provide the following `updates`:
+
+```json
+{
+  "auth.saml": {
+    "enabled": "true",
+    "single_logout": "false"
+}
+```
+it would enable SAML and disable single logouts. And, if you provide the following `removals`:
+```json
+{
+  "auth.saml": ["allow_idp_initiated"]
+}
+```
+
+it would remove the key/value setting identified by `allow_idp_initiated` within the `auth.saml`.
+So, the SAML service would be reloaded and that value would be inherited for either (settings `.ini` file,
+environment variable, command line arguments or any other accepted mechanism to provide configuration).
+
+Therefore, the complete HTTP payload would looks like:
+
+```json
+{
+  "updates": {
+    "auth.saml": {
+      "enabled": "true",
+      "single_logout": "false"
+    }
+  },
+  "removals": {
+    "auth.saml": ["allow_idp_initiated"]
+  }
+}
+```
+
+In case any of these settings cannot be overridden nor valid, it would return an error and these settings
+won't be persisted into the database.
+
+## Background job (high availability set-ups)
+
+Grafana Enterprise has a built-in scheduled background job that looks into the database every minute for
+settings updates. If there are updates, it reloads the Grafana services affected by the detected changes. 
+
+The background job synchronizes settings between instances in high availability set-ups. So, after you perform some changes through the
+HTTP API, then the other instances are synchronized through the database and the background job.
