Hey @Alan-Daniel
I assume you wanted the first two items of blobJson. In that case you can do something like this:
# importing the requests and ast library import requests import ast # api-endpoint URL = "https://ws1.chic.ulster.ac.uk/SensorCentral/REST/SensorDataRangeNanos/flgSh9oHnutzvZVOnnixFNjXIda2zula_101_101?startTs=1594297110372000000&endTs=1594297110372000000" # sending get request and saving the response as response object r = requests.get(url = URL) # extracting data in json format data = r.json() # Get value for blobJson blobJson = data[0]["blobJson"] # Convert string to list list = ast.literal_eval(blobJson) # Get first two items in list firstTwo = list[:2] # Print first two items of list print(firstTwo)Let me know if that worked for you.

Hey @Alan-Daniel
How about something like this:
# importing the requests library import requests # api-endpoint URL = "https://ws1.chic.ulster.ac.uk/SensorCentral/REST/SensorDataRangeNanos/flgSh9oHnutzvZVOnnixFNjXIda2zula_101_101?startTs=1594297110372000000&endTs=1594297110372000000" # sending get request and saving the response as response object r = requests.get(url = URL) # extracting data in json format data = r.json() # Printing the results print(data)source: https://www.geeksforgeeks.org/get-post-requests-using-python/

@avan said in How to retrieve data from a specific REST endpoint. (prefer using Python):
equests.get(url = URL)
extracting data in json format
data = r.json()
Get value for blobJson
blobJson = data[0]["blobJson"]
Convert string to list
yes, thanks! it works well!
