@Jhaydon - I’m in the process of putting a script together to gather survey responses from multiple surveys.  I plan to build in the handling of the scrollID for pagination.  Once I’m done and have it working, I’ll post some snippets here.

@Jhaydon - Hoping this will help you with whatever you’re writing up from a Python perspective:
 

############################################
# FUNCTION TO GET API CALL WITH SCROLLING. 
# Reference API documentation:
# https://gainsightpx.docs.apiary.io/#reference/surveyresponse
############################################

def get_surveyresponsesapi(engagementId, scrollId):

    if scrollId == "":
        # Set the request url for the first page of results
        url = BASE_URL + "/v1/survey/responses?filter=engagementId=="+ engagementId + "&pageSize=" + str(API_PAGE_SIZE) + "&sort=-date"

    else:
        # Set the request url for the subsequent pages of results
        url = BASE_URL + "/v1/survey/responses?filter=engagementId=="+ engagementId + "&pageSize=" + str(API_PAGE_SIZE) + "&sort=-date" + "&scrollId=" + scrollId

    payload={}
    headers = {
    'Accept': 'application/json',
    API_KEY_NAME: API_KEY_VALUE
    }

    # Make the API call
    return requests.request("GET", url, headers=headers, data=payload)


############################################
# SETTING UP TO PARSE THE API CALL(S)
############################################

# create a counter for the number of survey responses returned
totalResponseCount = 1
currentresponsecount = 0
currentScrollId = ""

# Does currentresponsecount < totalResponseCount? If so, we need to scroll through the results
# Good Reference:   https://jonathansoma.com/lede/foundations-2018/classes/apis/multiple-pages-of-data-from-apis/


##############################################################################
# LOOP WHILE CURRENT RESPONSE COUNT IS LESS THAN TOTAL COUNT RETURNED BY API
##############################################################################

while currentresponsecount < totalResponseCount:

    # Make the API call
    surveyResponses = get_surveyresponsesapi(engagement, currentScrollId)

    if surveyResponses.status_code == 200:
        #Successful API call

        # Parse the response as JSON
        responseData = surveyResponses.json()

        # Extract the list of surveys from the JSON response
        responses = responseDataD'results']

        # Increase the totalResponseCount by the API's count of total responses
        # Note this may update if new responses are received while we parse each page.
        totalResponseCount = responseDataD'totalHits']

        # count the number of responses returned in this page of API responses
        currentresponsecount = currentresponsecount + len(responses)

        # set the scrollId for the next page of results
        currentScrollId = responseDataD'scrollId']

        ######################################
        # DO THE WORK THEN LOOP
        ######################################


    else:
        Print("Error: " + surveyResponses.status_code)

Looking forward to it @rterakedis 

@revathimenon  - I posted a response last week with some python code snippets, but it looks like it had to get reviewed by a moderator.   Can you please review and post it?   Thank you!

@rterakedis - the code must have alerted the system for spam check.

Approved it now, thanks for sharing! 

If you’re looking for something more complete, I put a sanitized/slimmed down version that also supports “last x days” filtering in GitHub:  https://gist.github.com/rterakedis/437614bb6de6d5e74b9128de0de20c1f
