Seller teams already living in Google Sheets often want to use it as the control layer, pulling Amazon FBA performance data in rather than pushing Sheets data out. The integration pattern here is read-heavy: a scheduled scenario in Make or n8n queries the Amazon SP-API on a defined interval and writes inventory levels, suppressed listings, or pending orders into a named tab in the master spreadsheet. Finance teams use this to track FBA fee trends over time; ops teams use it as an early-warning dashboard for stranded inventory or order defect rate anomalies. Because Amazon doesn't offer a native Sheets connector, a middleware tool is required. Make's Amazon module and n8n's HTTP node are the two most reliable paths.
