+# Update cross-cluster API key API examples
+
+The [update cross-cluster API key API](https://www.elastic.co/docs/api/doc/elasticsearch/v9/operation/operation-security-update-cross-cluster-api-key) updates the attributes of an existing cross-cluster API key, which is used for API key based remote cluster access. This page shows you examples of using this API.
+
+## Create a cross-cluster API key
+
+If you create a cross-cluster API key as follows:
+
+```console
+POST /_security/cross_cluster/api_key
+{
+  "name": "my-cross-cluster-api-key",
+  "access": {
+    "search": [
+      {
+        "names": ["logs*"]
+      }
+    ]
+  },
+  "metadata": {
+    "application": "search"
+  }
+}
+```
+
+A successful call returns a JSON structure that provides API key information. For example:
+
+```console-result
+{
+  "id": "VuaCfGcBCdbkQm-e5aOx",
+  "name": "my-cross-cluster-api-key",
+  "api_key": "ui2lp2axTNmsyakw9tvNnw",
+  "encoded": "VnVhQ2ZHY0JDZGJrUW0tZTVhT3g6dWkybHAyYXhUTm1zeWFrdzl0dk5udw=="
+}
+```
+
+% TESTRESPONSE[s/VuaCfGcBCdbkQm-e5aOx/$body.id/]
+% TESTRESPONSE[s/ui2lp2axTNmsyakw9tvNnw/$body.api_key/]
+% TESTRESPONSE[s/VnVhQ2ZHY0JDZGJrUW0tZTVhT3g6dWkybHAyYXhUTm1zeWFrdzl0dk5udw==/$body.encoded/]
+
+## Inspect the API key
+
+To retrieve key information about the API key, including the exact role descriptor, use the [Get API key API](https://www.elastic.co/docs/api/doc/elasticsearch/v9/operation/operation-security-get-api-key).
+
+```console
+GET /_security/api_key?id=VuaCfGcBCdbkQm-e5aOx
+```
+
+% TEST[s/VuaCfGcBCdbkQm-e5aOx/$body.id/]
+% TEST[continued]
+
+A successful call returns a JSON structure that contains the information of the API key:
+
+```js

+  "api_keys": [

+% NOTCONSOLE
+
+1. Role descriptor corresponding to the specified `access` scope at creation time.
+In this example, it grants cross cluster search permission for the `logs*` index pattern.
+2. The `access` corresponds to the value specified at API key creation time.
+
+## Update access permissions and metadata
+
+The following example updates the API key created above, assigning it new access scope and metadata:
+
+```console
+PUT /_security/cross_cluster/api_key/VuaCfGcBCdbkQm-e5aOx
+{
+  "access": {
+    "replication": [
+      {
+        "names": ["archive"]
+      }
+    ]
+  },
+  "metadata": {
+    "application": "replication"
+  }
+}
+```
+
+% TEST[s/VuaCfGcBCdbkQm-e5aOx/\${body.api_keys.0.id}/]
+% TEST[continued]
+
+A successful call returns a JSON structure indicating that the API key was updated:
+
+```console-result
+{
+  "updated": true
+}
+```
+
+The API key's permissions after the update can be inspected again with the [Get API key API](https://www.elastic.co/docs/api/doc/elasticsearch/v9/operation/operation-security-get-api-key) and it will be:
+
+```js

+In this example, it is updated to grant the cross cluster replication permission
+for the `archive*` index pattern.
