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.
