# getVersion

The `getVersion` method retrieves version information for one or more applications installed on the device, such as agamento, spi, or ashrait. It returns the current version tags for each requested application.

## Request

<Note>
  **JSON-RPC 2.0**

  All methods in TweezerComm follow a JSON-RPC 2.0 structure. See [Get Started](/docs/integrate-pos-device/tweezercomm/tweezercomm-get-started) for more details on how the requests are structured and sent.
</Note>

In the request, the `method` field needs to be set to `getVersion` and the params must include an array of application names, as shown in the example request below:

```json theme={null}
{
    "jsonrpc": "2.0",
    "method": "getVersion",
    "id": "123454352",
    "params": [
        [
            "agamento",
            "spi",
            "ashrait"
        ]
    ]
}
```

## Response

A successful request will return a response similar to the one in the code block below:

```json theme={null}

    "jsonrpc": "2.0",
    "id": "123454352",
    "result": [
        "01.05.00",
