# sendGeneralEvent

The `sendGeneralEvent` method allows the terminal to communicate specific operational events or status updates to the system. This is mainly used to monitor the results of background processes such as periodic communications, setup routines, or reporting transaction-specific data.

## 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 `sendGeneralEvent`, as shown in the example below:

```json theme={null}
