+# ledger_current
+[[Source]](https://github.com/XRPLF/rippled/blob/master/src/ripple/rpc/handlers/LedgerCurrent.cpp "Source")
+
+The `ledger_current` method returns the unique identifiers of the current in-progress [ledger](../../../../concepts/ledgers/index.md). This command is mostly useful for testing, because the ledger returned is still in flux.
+
+## Request Format
+
+An example of the request format:
+
+{% tabs %}
+
+{% tab label="WebSocket" %}
+```json
+{
+   "id": 2,
+   "command": "ledger_current"
+}
+```
+{% /tab %}
+
+{% tab label="JSON-RPC" %}
+```json
+{
+    "method": "ledger_current",
+    "params": [
+        {}
+    ]
+}
+```
+{% /tab %}
+
+{% tab label="Commandline" %}
+```sh

+{% /tab %}
+
+{% /tabs %}
+
+[Try it! >](/resources/dev-tools/websocket-api-tool#ledger_current)
+
+The request contains no parameters.
+
+
+## Response Format
+An example of a successful response:
+
+{% tabs %}
+
+{% tab label="WebSocket" %}
+```json
+{
+  "id": 2,
+  "status": "success",
+  "type": "response",
+  "result": {
+    "ledger_current_index": 6643240
+  }
+}
+```
+{% /tab %}
+
+{% tab label="JSON-RPC" %}
+```json
+200 OK
+
+{
+    "result": {
+        "ledger_current_index": 8696233,
+        "status": "success"
+    }
+}
+```
+{% /tab %}
+
+{% tab label="Commandline" %}
+```json
+{
+   "result" : {
+      "ledger_current_index" : 56844050,
+      "status" : "success"
+   }
+}
+```
+{% /tab %}
+
+{% /tabs %}
+
+The response follows the [standard format][], with a successful result containing the following field:
+
+| `Field`                | Type                                | Description   |
+|:-----------------------|:------------------------------------|:--------------|
+| `ledger_current_index` | Unsigned Integer - [Ledger Index][] | The ledger index of this ledger version. |
+
+A `ledger_hash` field is not provided, because the hash of the current ledger is constantly changing along with its contents.
+
+## Possible Errors
