Basic API Workflow

Sample Python Code

“`python
import requests
import hashlib
import hmac
import time

api_key = “YOUR_API_KEY”
secret_key = “YOUR_SECRET_KEY”

def get_balance():
timestamp = str(int(time.time()))
method = “GET”
request_path = “/api/v5/account/balance”
message = timestamp + method + request_path
signature = hmac.new(secret_key.encode(), message.encode(), hashlib.sha256).hexdigest()

headers = {
    "OK-ACCESS-KEY": api_key,
    "OK-ACCESS-SIGN": signature,
    "OK-ACCESS-TIMESTAMP": timestamp
}

response = requests.get("https://www.okx.com" + request_path, headers=headers)
return response.json()

“`
