Shopee Product Monitor
Real-time product data extraction via reverse-engineered API. Pricing changes, stock levels, seller ratings, and review sentiment. Daily automated delivery to Google Sheets.
The challenge.
An e-commerce brand selling across Southeast Asian marketplaces needed daily competitive intelligence on Shopee — the largest platform in the region. They were manually checking competitor prices and stock levels for 2,000+ SKUs across 5 country stores, burning 20+ hours per week.
The approach.
API Reverse Engineering
Analyzed Shopee's mobile and web API traffic to map internal endpoints for product details, pricing, stock, and seller metrics. Built request authenticators for each of Shopee's 5 target country stores (SG, MY, TH, PH, VN).
Multi-Country Pipeline
Designed a pipeline that runs sequentially across country stores with country-specific proxy pools and request headers. Handles currency conversion and locale differences automatically.
Price & Stock Change Detection
Stores historical snapshots and computes daily deltas for price changes, stock level shifts, and rating movements. Generates alerts when competitors drop prices by more than 5% or run flash sales.
Google Sheets Delivery
Automated daily push to Google Sheets with per-country tabs, conditional formatting for price drops, and a summary dashboard sheet with trend charts that update automatically.
Sample output.
