使用Google Sheets脚本编辑器调用Kraken API：AddOrder参数位置疑问

Hey there! Nice job getting the balance check working already—you’re halfway there. Let’s clear up how to send those pair, type, and ordertype parameters to the AddOrder endpoint.

First off, Kraken’s private API endpoints (like /0/private/AddOrder) require a POST request, and all your order-specific parameters (plus mandatory auth fields) go directly in the request body. You can’t tack them onto the URL like you might with some public endpoints.

Here’s a concrete example using Python (super common for API testing): #

import requests
import time
import urllib.parse
import hashlib
import hmac
import base64

# Replace these with your actual Kraken API credentials
API_KEY = "your_kraken_api_key"
API_SECRET = "your_kraken_api_secret"

# Your order details—this is where you define your core parameters
order_details = {
    "pair": "XBTUSD",          # The trading pair you’re targeting
    "type": "buy",             # Use "buy" or "sell" depending on your goal
    "ordertype": "limit",      # Options include "limit", "market", "stop-loss", etc.
    "price": "32000",          *# Required for limit orders—set your desired execution price*
    "volume": "0.001",         # How much of the asset you want to trade
    "nonce": str(int(time.time() * 1000000))  # Unique, incrementing number (critical for security)
}

# Generate the required API signature (Kraken’s way of verifying your request is legitimate)
url_path = "/0/private/AddOrder"
encoded_params = urllib.parse.urlencode(order_details).encode()
message = url_path.encode() + hashlib.sha256(str(order_details["nonce"]).encode() + encoded_params).digest()
signature = hmac.new(base64.b64decode(API_SECRET), message, hashlib.sha512)
api_sign = base64.b64encode(signature.digest()).decode()

# Set up headers with your API key and generated signature
headers = {
    "API-Key": API_KEY,
    "API-Sign": api_sign
}

# Send the POST request to Kraken
response = requests.post("https://api.kraken.com/0/private/AddOrder", data=order_details, headers=headers)
print(response.json())

Key things to keep in mind: #

• All order parameters live in the request body: Whether you’re using code, Postman, or another tool, input pair, type, ordertype, and related fields (like price for limits) as form data or JSON in the POST body.
• Don’t skip the auth requirements: The nonce (unique, incrementing number) and API-Sign (generated signature) are mandatory for all private endpoints. Kraken won’t process your order without these.
• Double-check parameter rules: For limit orders, you must include price; for market orders, you can omit it. Also, make sure your API key has "Trade" permissions enabled in your Kraken account settings—otherwise you’ll hit an authorization error.

If you’re using a tool like Postman instead of code, just set the request method to POST, add your parameters as "form-data" in the Body tab, then add the API-Key and API-Sign headers (you’ll need to generate the signature manually or use Postman’s pre-request script to automate it).
