Python example code for an authenticated call to Bitfinex API v1

bitfinex-python.py

import requests  # pip install requests

           'nonce':time.time(),
           'options':{}

#payload = {

payload_json = json.dumps(payloadObject)
print payload_json

r = requests.get(url, data={}, headers=headers)

print 'Response Code: ' + str(r.status_code) 
print 'Response Header: ' + str(r.headers)
print 'Response Content: '+ str(r.content)

hi:
run the code ,it returns Key symbol was not present.where is the problem?

@mingyun, you probably forgot the API key / secret. PS. Don't post these publically!

@jordanbaucke, I updated the URL to https://api.bitfinex.com/v1/ and the hashlib calls to m = hashlib.sha384(api_secret + payload).hexdigest(). BFX returns

Response Code: 400
Response Header: {'status': '400 Bad Request', ...}
Response Content: {"message":"Invalid X-BFX-SIGNATURE."}

Any ideas?

Streblo, I've had the same issue but fixed it. My working code is below, using Python 3.4:

#PYTHON 3.4
import requests
import json
import base64
import hashlib
import time
import hmac

bitfinexURL = 'https://api.bitfinex.com/v1/balances'
bitfinexKey = 'KEY HERE'
bitfinexSecret = b'SECRET KEY HERE' #the b is deliberate, encodes to bytes

def start():
    print("BitFinex")
    payloadObject = {
            'request':'/v1/balances',
            'nonce':str(time.time() * 100000), #convert to string
            'options':{}
    }

    payload_json = json.dumps(payloadObject)
    print("payload_json: ", payload_json)

    payload = base64.b64encode(bytes(payload_json, "utf-8"))
    print("payload: ", payload)

    m = hmac.new(bitfinexSecret, payload, hashlib.sha384)
    m = m.hexdigest()

    #headers
    headers = {
          'X-BFX-APIKEY' : bitfinexKey,
          'X-BFX-PAYLOAD' : base64.b64encode(bytes(payload_json, "utf-8")),
          'X-BFX-SIGNATURE' : m
    }

    r = requests.get(bitfinexURL, data={}, headers=headers)
    print('Response Code: ' + str(r.status_code))
    print('Response Header: ' + str(r.headers))
    print('Response Content: '+ str(r.content))

@mingyun, see following msg
@jordanbaucke, see following msg
@BitcoinResearch, see following msg:

I get the "Key symbol was not present" even thogh I provide the X-BFX-APIKEY header. I doublechecked that the key is correct.

Do you have any thought or suggestion here?

Hello

I saw commented code in sample that could enable me to make a trade. I looked at BitcoinResearch code example and wrote my info into it, but seems that I get no answer back from site. Also there is no trade. Wallet info is working fine. What could be the issue here?

Good! Thank you!

@BitcoinResearch

I've tried your code, but it is not working. Actually the response code it gets is 200 but the content is not right. Would you help me?

My code is like this:

import requests
import json
import base64
import hashlib
import time
import hmac

bitfinexURL = 'https://api.bitfinex.com/'
bitfinexKey = 'key'
bitfinexSecret = b'secret' #the b is deliberate, encodes to bytes

def start():
    print("BitFinex")
    payloadObject = {
            'request':'v1/order/new',
            'nonce':str(int(time.time()*1000000)), #convert to string
            'options':{'symbol':'tIOTUSD',
                     'amount':'100.00',
                     'price':'0.98500',
                     'exchange':'bitfinex',
                     'side':'buy',
                     'type':'limit'}
    }

    payload_json = json.dumps(payloadObject)
    print("payload_json: ", payload_json)

    payload = base64.b64encode(bytes(payload_json, "utf-8"))
    print("payload: ", payload)

    m = hmac.new(bitfinexSecret, payload, hashlib.sha384)
    m = m.hexdigest()

    #headers
    headers = {
          'X-BFX-APIKEY' : bitfinexKey,
          'X-BFX-PAYLOAD' : base64.b64encode(bytes(payload_json, "utf-8")),
          'X-BFX-SIGNATURE' : m
    }

    r = requests.get(bitfinexURL, data={}, headers=headers)
    print('Response Code: ' + str(r.status_code))
    print('Response Header: ' + str(r.headers))
    print('Response Content: '+ str(r.content))
