FBM Price and Quantity Feed and Automatic Distributor Orders with n8n
Update FBM listings from a distributor feed and place distributor orders automatically
The first replaced the manual morning upload of the listings spreadsheet; the second removed manual order creation.
Per source From an Amazon forum moderator's answer, not an official policy page.
Copy-paste prompt
Build an n8n workflow that runs at 6:00 every day: 1) download the distributor feed from [URL] (CSV: SKU, cost, quantity); 2) for each SKU in my Amazon FBM catalog, set quantity = distributor quantity minus a buffer of [2], and price = cost x [1.35] rounded to .99, within my min/max in the sheet [name]; 3) send the changes as one SP-API JSON_LISTINGS_FEED and email me the processing report. Skip any SKU missing from the feed and list it in the email.
The source didn't publish its exact prompt. We wrote this starter so you can try the same workflow. Replace anything in [brackets].
What they did
In an n8n community thread on SP-API workflows, an FBM seller described what his n8n workflows do for the business. One takes the distributor's data feed every morning and updates quantity and price on their Amazon listings. Another places an order on the distributor's site through its API whenever an Amazon order comes in.
How it went
The first replaced the manual morning upload of the listings spreadsheet; the second removed manual order creation. He was still building two more: posting the distributor's tracking numbers back to the Amazon order, and answering 'not delivered' buyer messages by pulling proof of delivery from the courier (Royal Mail, DPD, DHL) and replying with AI or a template.

Worth knowing
A first-hand forum reply without numbers. If your stock comes straight from a distributor, the morning feed is the piece that prevents overselling, so build it before the auto-ordering.
