Monitor Amazon MAP violations in offer listings with Google Sheets and ScrapeHero

## Amazon MAP Violation Monitor - Google Sheets + Offer Listings ### How it works This workflow manually checks Amazon listings for MAP violations using product ASINs and MAP prices from Google Sheets. It normalizes each input row, fetches current Amazon offer listings through ScrapeHero, combines them with previous offer history, and analyzes seller-level pricing changes. It then writes violation summaries and updated offer price history back to Google Sheets. ### Setup steps - Configure Google Sheets credentials in n8n for all Sheets nodes. - Configure the ScrapeHero credentials/API access for the Amazon offer listings node. - Set the input sheet to contain ASIN and MAP price columns expected by the normalization code. - Configure the previous offer history, violation output, and offer price history Google Sheets nodes to point to the correct spreadsheets, tabs, and columns. - Review the code nodes for expected field names and date/price formatting before running the manual trigger. ### Customization Adjust the analyzer code to change MAP violation rules, seller matching, price-change thresholds, or the output fields appended to Google Sheets.
