Step 1 — Create the New App Integration Account

Settings → Integrations → Add Integration → Amazon → Seller Central — Amazon as a sales channel

  • App type: trackstar_cart
  • Name it clearly (e.g. "FBM" or "Amazon FBM")
  • Authenticate to Amazon Seller Central when prompted
  • Enable Get Products

Step 2 — Map SKUs

Inside the new integration account → Manage Products:

  • Run Automap Product SKUs first to match Luminous SKUs to your Amazon FBM listings automatically
  • Review the results and manually map any SKUs that didn't automap
  • Any unmapped SKU will block orders from posting — confirm everything is mapped before going live

Step 3 — Update the FBM Channel

Manage → Channels → Edit your FBM channel

  • Get Orders Scroll to the Order Source section. Under Pull Orders From you'll see a dropdown showing your current integration account. Change this to your new trackstar_cart account. This controls where Luminous pulls incoming FBM orders from.
  • Push Stock to Integration Scroll to the Push Inventory Stocks and Costs section. Under Push To Integration Account, change the selected account to your new trackstar_cart account. This controls where Luminous sends your inventory quantities so your Amazon FBM listings stay up to date.
  • Warehouse Group In the same Push Inventory Stocks and Costs section, confirm the Warehouse Group dropdown is set to the warehouse where your FBM inventory lives. This should not have changed during the swap, but it's worth a quick check to make sure it didn't get cleared when you updated the integration account.
  • Once all three are updated, click Save at the bottom of the form.

Step 4 — Verify Before Decommissioning

  •  Settings → Integrations: new account shows SUCCESS on Get Products and Push Stock
  •  Trigger a manual stock push and confirm inventory updated on your Amazon FBM listings
  •  Confirm incoming orders are landing correctly in Luminous (not in purgatory)

Step 5 — Disable the Old ecart Account

Only once Step 4 is confirmed:

  • Deactivate the old FBM ecart integration account
  • Don't delete it right away — keep it available for reference until you're confident the new setup is stable

One thing to check after the swap: if you had any per-SKU buffer quantities configured on the FBM channel, verify those are still in place under Manage → Channels → Product Mapping.
