Issue in capturing historical data

Print out your start_timestamp and your yesterday_timestamp and put them into postman. If it doesn’t work there it’s not going to work in your code. 

You might need to divide both timestamps by 1000 before casting to int. I don’t remember if LM wants seconds or milliseconds and i don’t remember which one python gives you.

if i use this i am getting data

current_timestamp = int(datetime.utcnow().timestamp())

start_timestamp = int((datetime.utcnow() - timedelta(days=30)).timestamp())
queryParams =  f'?start={start_timestamp}&end={current_timestamp}'
print(start_timestamp)

From today to last 30 days we are getting data

epoch = str(int(time.time() * 1000))  ( both the cases we are using this)
