Is it possible to hit up the API and pull only new responses since the last pull, and is there a way to only pull particular fields from the survey? The code I'm currently using is:

downloadRequestUrl = baseUrl
downloadRequestPayload = '{"format":"' + fileFormat + '","surveyId":"' + surveyId + '"}'
downloadRequestResponse = requests.request("POST", downloadRequestUrl, data=downloadRequestPayload, headers=headers)
progressId = downloadRequestResponse.json()["result"]["id"]
print(downloadRequestResponse.text)

Thanks
