Json – Wootrade V3 API authentication in Python

I have taken the example code from https://docs.woo.org/?shell#authentication and have adapted the code to get the V3 normalised request to use in the signature generation. For endpoints that don’t require any parameters, this works fine, but if parameters are required, I get this error:

"{‘success’: False, ‘code’: -1001, ‘message’: ‘The API signature is invalid.’}"

I have checked my API key and secret and the settings on my account, and everything should be fine.

import datetime
import hmac, hashlib, base64
import requests
import json


staging_api_secret_key = 'MY API SECRET'
staging_api_key = 'MY API KEY'

def _generate_signature(data):
  key = staging_api_secret_key#'key' # Defined as a simple string.
  key_bytes= bytes(key , 'utf-8') # Commonly 'latin-1' or 'utf-8'
  data_bytes = bytes(data, 'utf-8') # Assumes `data` is also a string.
  return hmac.new(key_bytes, data_bytes , hashlib.sha256).hexdigest()


milliseconds_since_epoch = round(datetime.datetime.now().timestamp() * 1000)

headers = {
    'x-api-timestamp': str(milliseconds_since_epoch),
    'x-api-key': staging_api_key,
    'x-api-signature': _generate_signature(str(milliseconds_since_epoch)+'POST/v3/algo/order{ "symbol": "SPOT_BTC_USDT",  "side": "BUY",  "reduceOnly": false,  "type": "MARKET",  "quantity": "0.0001",  "algoType": "TRAILING_STOP",  "callbackRate": "0.012"}'),
    'Content-Type': 'application/json',
    'Cache-Control':'no-cache'
}
data = {"symbol": "SPOT_BTC_USDT",  "side": "BUY",  "reduceOnly": False,  "type": "MARKET",  "quantity": "0.0001",  "algoType": "TRAILING_STOP",  "callbackRate": "0.012"}



response = requests.post('https://api.woo.org/v3/algo/order', headers=headers, data=data)
print(response.json())

    Customer support came with the following code that seems to work:

    import datetime
import hashlib
from urllib.parse import urlencode
import hmac
import requests
import json
 
API_SECRET = ""
API_KEY = ""
API_ENDPOINT_BASE = ""
 
ts = round(datetime.datetime.now().timestamp() * 1000)
algo_order ={}
algo_order["symbol"] = "SPOT_BTC_USDT"
algo_order["side"] = "BUY"
algo_order["type"] = "MARKET"
algo_order["quantity"] = "1"
algo_order["algoType"] = "STOP"
algo_order["triggerPrice"] = "27500"
json_formatted_str = json.dumps(algo_order, indent=4)
#hashed_sig = hashlib.sha256(API_SECRET.encode('utf-8'))
def _generate_signature(data):
  key = API_SECRET#'key' # Defined as a simple string.
  key_bytes= bytes(key , 'utf-8') # Commonly 'latin-1' or 'utf-8'
  data_bytes = bytes(data, 'utf-8') # Assumes `data` is also a string.
  return hmac.new(key_bytes, data_bytes , hashlib.sha256).hexdigest()
 
sign = str(ts) + "POST/v3/algo/order"+json_formatted_str
api_endpoint = API_ENDPOINT_BASE + "v3/algo/order"
userdata = requests.post(api_endpoint,
                       headers={
                           "x-api-signature": _generate_signature(sign),
                           "x-api-timestamp": str(ts),
                           "x-api-key": API_KEY,
                           'Content-Type': 'application/json',
                       },data=json_formatted_str
)
print(userdata.json())

    It’s hard for me to tell exactly if this will work since I don’t have the actual API credentials, but you should try something like this:

    import json
import datetime
import requests
import hmac, hashlib


staging_api_secret_key = 'MY API SECRET'
staging_api_key = 'MY API KEY'


def _generate_signature(data):
    key = staging_api_secret_key  # 'key' # Defined as a simple string.
    key_bytes = bytes(key, 'utf-8')  # Commonly 'latin-1' or 'utf-8'
    data_bytes = bytes(data, 'utf-8')  # Assumes `data` is also a string.
    return hmac.new(key_bytes, data_bytes, hashlib.sha256).hexdigest()


milliseconds_since_epoch = round(datetime.datetime.now().timestamp() * 1000)
data = {"symbol": "SPOT_BTC_USDT", "side": "BUY", "reduceOnly": False, "type": "MARKET", "quantity": "0.0001", "algoType": "TRAILING_STOP", "callbackRate": "0.012"}
headers = {
    'x-api-timestamp': str(milliseconds_since_epoch),
    'x-api-key': staging_api_key,
    'x-api-signature': _generate_signature(f'{milliseconds_since_epoch}POST/v3/algo/order{json.dumps(data)}'),
    'Content-Type': 'application/json',
    'Cache-Control': 'no-cache'
}


response = requests.post('https://api.woo.org/v3/algo/order', headers=headers, data=data)
print(response.json())

    The difference is that I am created the signature with the exact data in the dictionary, using json.dumps(data). Let me know if this works for you, and if not, what error messages you see.
