Building a Python Script for Amazon Bestseller Trend Alerts

Building a Python Script for Amazon Bestseller Trend Alerts

For Amazon businesses and market analysts, staying ahead of the competition requires constant monitoring of product performance. Tracking bestseller trends can reveal valuable insights into market demand, emerging opportunities, and potential threats. This blog post guides you through building a Python script that leverages the SellerMagnet API to monitor Amazon bestseller trends and receive timely alerts.

Why Track Amazon Bestseller Trends?

Monitoring bestseller ranks offers numerous strategic advantages:

• Competitive Analysis: Identify competitor strengths and weaknesses by tracking their product rankings.
• Inventory Management: Optimize inventory levels based on real-time demand fluctuations reflected in bestseller lists.
• Market Research: Discover emerging product categories and trending items to inform product development and marketing strategies.
• Early Threat Detection: Identify potential market saturation or declining demand for existing products.

Leveraging SellerMagnet's API for Bestseller Tracking

SellerMagnet provides an enterprise-grade Amazon data API, offering a reliable and efficient way to access real-time product data. Our API eliminates the need for unreliable and legally questionable Amazon Web Scraping techniques. We will utilize the Amazon Product Statistics endpoint for this project.

Setting Up Your Python Environment

Before diving into the code, ensure you have Python installed (preferably version 3.6 or higher). You'll also need to install the requests library to make HTTP requests to the SellerMagnet API.

pip install requests

The Python Script

Here's a Python script to fetch bestseller rank data and trigger alerts based on predefined thresholds:

import requests
import json

API_KEY = "YOUR_API_KEY" # Replace with your actual SellerMagnet API key
ASIN = "B08N5WRWNW" # Replace with the ASIN of the product you want to track
MARKETPLACE_ID = "ATVPDKIKX0DER" # Replace with the desired marketplace ID (e.g., US)

# Function to fetch product statistics
def get_product_stats(asin, marketplace_id, api_key):
    url = f"https://sellermagnet-api.com/amazon-product-statistics?asin={asin}&marketplaceId={marketplace_id}&api_key={api_key}"
    try:
        response = requests.get(url)
        response.raise_for_status()  # Raise HTTPError for bad responses (4xx or 5xx)
        data = response.json()
        return data
    except requests.exceptions.RequestException as e:
        print(f"Error fetching data: {e}")
        return None

# Function to check for bestseller rank changes and trigger alerts
def check_bestseller_rank(asin, marketplace_id, api_key, threshold):
    product_data = get_product_stats(asin, marketplace_id, api_key)
    if product_data and product_data["success"]:
        rank = product_data["data"]["bestSellerRank"]
        print(f"Current Bestseller Rank for {asin}: {rank}")
        if rank > threshold:
            print(f"ALERT: Bestseller rank has exceeded the threshold of {threshold}!")
            # Add your alerting mechanism here (e.g., send an email)
        else:
            print("Bestseller rank is within acceptable limits.")
    else:
        print("Failed to retrieve bestseller rank.")

# Example usage
THRESHOLD = 100 # Set your desired threshold for bestseller rank

check_bestseller_rank(ASIN, MARKETPLACE_ID, API_KEY, THRESHOLD)

Before running the script, remember to replace YOUR_API_KEY, B08N5WRWNW, and ATVPDKIKX0DER with your actual API key, the product's ASIN, and the appropriate Amazon Categories marketplace ID. The THRESHOLD variable defines the bestseller rank at which you want to trigger an alert.
