How to Change Ad Price on Binance Using Python: A Step-by-Step Guide

Programmatically changing the price of an ad on the Binance exchange

Modern cryptocurrency traders are increasingly turning to automation of routine processes. This is especially relevant for P2P traders, where it is important to quickly adapt to market conditions.

In this article, we will show how you can change the price of your ad in Python using the Binance API. We will provide a working example of the code and tell you what you should pay attention to when using it.

Why Automate Ad Price Changes?

Automating ad price adjustments allows you to:

• ⚡ Quickly respond to market fluctuations

• 📉 Reduce the risk of financial losses

• 💼 Optimize business processes

• ⏰ Save traders’ time

What Do You Need to Get Started?

Before you begin coding, make sure to:

1. Obtain your Binance API keys.

2. Ensure your account is a verified merchant (only merchants can modify ads via the API).

3. Install the requests, library if it’s not already installed:

pip install requests

Code Example: Changing Ad Price

Below is a working Python example:

import time
import hmac, hashlib
import requests

class BinanceAPI:
    def __init__(self, api_key, api_secret):
        self.api_key = api_key
        self.api_secret = api_secret

    def getServerTime(self):
        return int(time.time() * 1000)

    def getSignature(self):
        query_string = f"timestamp={self.getServerTime()}"
        return hmac.new(self.api_secret.encode("utf-8"), query_string.encode("utf-8"), hashlib.sha256).hexdigest()

    def getApiKey(self):
        return self.api_key

    def edit_ad(self, adv_num, new_price):
        payload = {'advNo': adv_num, 'price': new_price}
        params = {'timestamp': self.getServerTime(), 'signature': self.getSignature()}
        headers = {"Content-Type": "application/json", "X-MBX-APIKEY": self.getApiKey()}

        res = requests.post('https://api.binance.com/sapi/v1/c2c/ads/update?', headers=headers, json=payload, params=params).json()

        if res.get('code') == -1002:
            print("Access error: Merchant keys required.")
        elif res.get('success'):
            print(f"Price changed: ad {adv_num} - new price {new_price}")
        else:
            print(f"Price change error: {res.get('message', 'Unknown error')}")

        return res

Example Usage:

if __name__ == '__main__':
    api = BinanceAPI("YOUR_API_KEY", "YOUR_API_SECRET")
    api.edit_ad("1234567890987654321", "46")

Possible Errors and How to Fix Them

• code -1002:  Access denied. Make sure you are using merchant API keys.

• success: False:  Check if the ad ID is correct.

• 403 or 401 errors: Authorization issue — verify your API keys.
