Historical API returns error 400!!!! - Python

SKExplorer

Historical API keeps returning Http Status 400 even with the EXAMPLE GIVEN!!!!! why ?

here is my code...

http = urllib3.PoolManager()
API_ENDPOINT = "https://apiconnect.angelbroking.com/rest/secure/angelbroking/historical/v1/getCandleData"

#thirty_days_ago = datetime.now() - timedelta(days=30)
#from_date = thirty_days_ago.strftime("%Y-%m-%d %H:%M")
#to_date = datetime.now().strftime("%Y-%m-%d %H:%M")

from_date = "2021-07-01 09:41"
to_date = "2021-07-29 10:41"

print(from_date)
print(to_date)

payload = { "exchange": "NSE",    
            "symboltoken": "3045",
             "interval": "ONE_HOUR",  
            "fromdate": from_date,
             "todate": to_date
             }


encoded_data = json.dumps(payload).encode('utf-8')

r = http.request('POST', API_ENDPOINT,
                headers=headers,
                
                body=encoded_data)

print(r.status)
print('DRAW:',r.data)
resp_body = r.data.decode('utf-8')
print(f'DATA:{resp_body}')

@Moderator_2 I have tried smartApi.getCandleData, I get the same http 400 error....http response has no error message either to debug!!!!

Is there something additional to be added to the HEADER data for Historical API ? I am successfully sing the same header to retrieve quote data.

can you try my code and see whats wrong ?

@Moderator_2 I am posting the code again.....

http = urllib3.PoolManager()
API_ENDPOINT = "https://apiconnect.angelbroking.com/rest/secure/angelbroking/historical/v1/getCandleData"

#thirty_days_ago = datetime.now() - timedelta(days=30)
#from_date = thirty_days_ago.strftime("%Y-%m-%d %H:%M")
#to_date = datetime.now().strftime("%Y-%m-%d %H:%M")

from_date = "2021-07-01 09:41"
to_date = "2021-07-29 10:41"

print(from_date)
print(to_date)

payload = { "exchange": "NSE",
"symboltoken": "3045",
"interval": "ONE_HOUR",
"fromdate": from_date,
"todate": to_date
}

encoded_data = json.dumps(payload).encode('utf-8')

r = http.request('POST', API_ENDPOINT,
headers=headers,

        body=encoded_data)

print(r.status)
print('DRAW:',r.data)

resp_body = r.data.decode('utf-8')
print(f'DATA:{resp_body}')

Hi @SKExplorer

As verified on the API request params from the shared code snippet, we are able to retrieve the response without facing 400 status code. Please refer our working python SDK getCandleData() function

@Moderator_2 below is the simple code that I am testing... I am trying off market hours not live...

http = urllib3.PoolManager()
API_ENDPOINT = "https://apiconnect.angelbroking.com/rest/secure/angelbroking/historical/v1/getCandleData"

#thirty_days_ago = datetime.now() - timedelta(days=30)
#from_date = thirty_days_ago.strftime("%Y-%m-%d %H:%M")
#to_date = datetime.now().strftime("%Y-%m-%d %H:%M")

from_date = "2021-07-01 09:41"
to_date = "2021-07-29 10:41"

print(from_date)
print(to_date)

payload = { "exchange": "NSE",
"symboltoken": "3045",
"interval": "ONE_HOUR",
"fromdate": from_date,
"todate": to_date
}

encoded_data = json.dumps(payload).encode('utf-8')

r = http.request('POST', API_ENDPOINT,
headers=headers,

            body=encoded_data)

print(r.status)
print('DRAW:',r.data)

resp_body = r.data.decode('utf-8')
print(f'DATA:{resp_body}')
