Amazon Product Price Tracker

Companion code for a YouTube video showing how to track amazon product prices with HasData HasData Amazon Products API.

Tutorial project: Track prices for amazon products. Save data as a CSV file, then send a notification to the user when the product becomes cheap enough to purchase.

This repository runs main.py to do the following:

• Read the settings files, where user inputs the products to track
• Uses HasData Amazon Scraper to find the product prices the user wants to track.
• Saves the results in the repo output/product_data.csv
• Sends a notification if the price drops below a threshold defined by the settings/price_threshold.txt.
• Repeats the scan every hour.

Quick Start

pip install -r requirements.txt

Create .env

HASDATA_API_KEY=your_api_key_here
BOT_TOKEN=telegram_bot_token
BOT_CHAT_ID=telegram_chat_id

Run the main file:
