When use Web Service Endpoint have feature to transformation Json data format

in Acumatica I am exposing data of purchases order by Web service endpoint but json data is not in expected format as required, do acumatica have feature to transformation Json data format.

Acumatica json format:

{ "id": "81f542f0-42d5-ed11-9272-00155d056707", "rowNumber": 1, "note": { "value": "" }, "warehouseCode": { "value": "01" }, "type": { "value": "PO" }, "supplyNo": { "value": "123" }, "lineID": { "value": "1" }, "custom": {}, "_links": { "self": "/AcumaticaSmartFactory/entity/ewsfendpoint/22.200.001/PurchaseOrder/81f542f0-42d5-ed11-9272-00155d056707", "files:put": "/AcumaticaSmartFactory/entity/ewsfendpoint/22.200.001/files/PX.Objects.PO.POOrderEntry/Document/81f542f0-42d5-ed11-9272-00155d056707/{filename}" } }

Required json format:

    {
        "warehouseCode": "01",
        "type": "Purchase Order",
        "supplyNo": "123",
        "lineID": 0         
    }
