futures fetch_balance returns balances=0.0

Hi, I’m working with ccxt version 1.62.29 in python. I have a testnet futures account in binance, which has 100000 USDT as margin balance. I can see it at testnet.binancefuture.com plataform. But I would like to get that data with my python script, using ccxt. Mi code is:

import sys
import numpy as np
import ccxt


from sandapi01 import *  #Sandbox futures
#from config_01 import *  #real futures

print('ccxt version:',ccxt.__version__ )

# from variable id
exchange_id = 'binance'
exchange_class = getattr(ccxt, exchange_id)
exchange = exchange_class({
   "apiKey": API[exchange_id],
    "secret": SECRET[exchange_id],
    "adjustForTimeDifference": True,
    "enableRateLimit": True,
    "options": {
        'defaultType': 'future',
    },
})

print('nombre:', exchange.name)
markets = exchange.load_markets()
print(exchange.requiredCredentials)  

balances= exchange.fetch_balance()
print(balances['USDT'])

And what I get is:

ccxt version: 1.62.29
nombre: Binance
{'apiKey': True, 'secret': True, 'uid': False, 'login': False, 'password': False, 'twofa': False, 'privateKey': False, 'walletAddress': False, 'token': False}
{'free': 0.0, 'used': 0.0, 'total': 0.0}

As you can see, the values are all zeros, and I don’t know how to get the actual USDT balance.

Thank you Kroitor, that code works. I will do later what you say. Thanks again and best regards

@pedruntu does this snippet work for you (with my testnet keys):

import ccxt

print('CCXT Version:', ccxt.__version__)

exchange = ccxt.binanceusdm({
        "apiKey": "16db8b4176457d63fdc0fd8b2c9418f669237cc9620c8c04c3b8973c7e0c39b3",
        "secret": "a0d07130b34f3debfcfe29d9faf5d2fcf6bdc3b83566d03a0a973a6bc4ab90a4"
})

exchange.set_sandbox_mode(True)
markets = exchange.load_markets()

# exchange.verbose = True  # uncomment for debugging purposes

balances= exchange.fetch_balance()
print(balances['USDT'])

If it works with my keypair, then replace it with your keys. If it doesn’t work with your keys, check your keys (make sure they’re correct and you’ve set proper permissions on them, if necessary, recreate your keypair and try a fresh new keypair, see: https://github.com/ccxt/ccxt/wiki/Manual#troubleshooting )
