Hi there,
I’m new to Binance API, I want to create a new order on Binance Futures but I get an error like this:
Here is what I tried to do (Actually, I followed this example: https://github.com/binance-exchange/binance-signature-examples/blob/master/python/futures.py):
import hmac
import time
import hashlib
import requests
import json
from urllib.parse import urlencode
KEY = API_KEY
SECRET = API_SECRET
BASE_URL = 'https://fapi.binance.com' # production base url
def hashing(query_string):
return hmac.new(SECRET.encode('utf-8'), query_string.encode('utf-8'), hashlib.sha256).hexdigest()
def get_timestamp():
return int(time.time() * 1000)
def dispatch_request(http_method):
session = requests.Session()
session.headers.update({
'Content-Type': 'application/json;charset=utf-8',
'X-MBX-APIKEY': KEY
})
return {
'GET': session.get,
'DELETE': session.delete,
'PUT': session.put,
'POST': session.post,
}.get(http_method, 'GET')
# used for sending request requires the signature
def send_signed_request(http_method, url_path, payload={}):
query_string = urlencode(payload)
# replace single quote to double quote
query_string = query_string.replace('%27', '%22')
if query_string:
query_string = "{}×tamp={}".format(query_string, get_timestamp())
else:
query_string = 'timestamp={}'.format(get_timestamp())
url = BASE_URL + url_path + '?' + query_string + '&signature=' + hashing(query_string)
print("{} {}".format(http_method, url))
params = {'url': url, 'params': {}}
response = dispatch_request(http_method)(**params)
return response.json()
# used for sending public data request
def send_public_request(url_path, payload={}):
query_string = urlencode(payload, True)
url = BASE_URL + url_path
if query_string:
url = url + '?' + query_string
print("{}".format(url))
response = dispatch_request('GET')(url=url)
return response.json()
### public data endpoint, call send_public_request #####
# get klines
response = send_public_request('/fapi/v1/klines' , {"symbol": "BTCUSDT", "interval": "1d"})
print(response)
# get account informtion
# if you can see the account details, then the API key/secret is correct
response = send_signed_request('GET', '/fapi/v2/account')
print(response)
### USER_DATA endpoints, call send_signed_request #####
# place an order
# if you see order response, then the parameters setting is correct
# if it has response from server saying some parameter error, please adjust the parameters according the market.
params = {
"symbol": "BNBUSDT",
"side": "BUY",
"type": "LIMIT",
"timeInForce": "GTC",
"quantity": 1,
"price": "15"
}
response = send_signed_request('POST', '/fapi/v1/order', params)
print(response)
I tried to Google that error but still didn’t know why I encountered it and how to fix it. I’m sure that the API_KEY is accurate and valid. I also don’t restrict IP address.
I tested on testnet and it worked well
Hope you can give me some help. Thanks a lot
