You can check the REST API documentation here.
The JSON request message for above get_data request will be:
POST https://product.datastream.com/DSWSClient/V1/DSService.svc/rest/GetData { "DataRequest": { "Instrument": { "Properties": null, "Value": "<VOWG_p.DE>" }, "DataTypes": [{ "Properties": null, "Value": "VO" }, { "Properties": null, "Value": "P" } ], "Date": { "End": "", "Frequency": "", "Kind": 1, "Start": "2017-01-01" }, "Tag": null }, "Properties": { "Key": "Source", "Value": null }, "TokenValue": "**** TOKEN VALUE *****" }

Hi @YD,
If you are using Python, I would recommend to use the DSWS library for requests, and invoke the API like:
df = ds.get_data(tickers='<VOWG_p.DE>', fields=['VO','P'], start='2017-01-01', kind=1)
which returns a dataframe with all the values.
To get the list of all the fields, please use the Datastream Navigator.
