# doPeriodic

The `doPeriodic` method should be called at least once a day to deposit transactions and update the AEA database. This method generates a Z report summarizing the day's transactions.

## Request

<Note>
  **JSON-RPC 2.0**

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

In the request, ensure to configure the following:

* The `method` field must be set to `doPeriodic`.
* The service must be set to `ashrait` in the `params`.
* An optional string specifying the report format (`narrow`, `medium`, `wide`, or `xml`)

The request contains a list of parameters that can include a `forceUpdateParams` boolean flag to force the terminal to update its retailer parameters.

```json theme={null}
{
    "jsonrpc": "2.0",
    "method": "doPeriodic",
    "params": [
        "ashrait",
        "wide",
        {
            "forceUpdateParams": true
        }
    ],
    "id": 2
}
```

### Request Parameters

This method's parameters are a list of values, not a dictionary.

* Service Name (string, mandatory): The service name. Currently, this is a fixed value: ashrait.
* Report Format (string, optional): The format of the report. Values include narrow, medium, wide, or xml.
* Force Update (boolean, optional): An optional dictionary with a `forceUpdateParams` key. When true, it forces the terminal to update the retailer parameters.
