This is the complete guide to selling on Amazon — from authorizing your Seller account to mapping products, syncing inventory, and pulling orders into your unified inbox.
ℹ️ Before you start: you’ll need an active Amazon Seller Central account on the Professional plan, admin access to authorize apps, and your products already in the catalog with clean SKUs.
1. Connect your Seller account
- Open the Amazon channel — go to Channels and select Amazon, then click Connect.
- Authorize via Amazon — sign in with your Seller Central admin account and approve the requested permissions.
- Select your marketplace — choose the Amazon marketplace(s) you sell in (e.g. amazon.com).
✅ Once connected, the channel status shows Connected and begins its first sync. No inventory or price is pushed until you map products.
2. Map products to Amazon listings
Amazon identifies products by ASIN. You either match an existing ASIN or create a new listing.
Match to an existing ASIN
- From the Amazon channel, open Listings → Map products.
- Provide the product’s UPC/EAN/GTIN or ASIN. The system validates it against Amazon’s catalog.
- Review the matched detail page and confirm. Your SKU is now tied to that ASIN.
Create a new listing
- Choose the closest product type in Amazon’s taxonomy.
- Fill the required attributes — these pull from your catalog attributes where mapped.
- Submit. Amazon processes new listings asynchronously.
⚠️ Brand gating & restricted categories: some brands and categories are gated on Amazon and require Brand Registry or category approval on Amazon’s side. Resolve gating in Seller Central — the platform can’t bypass Amazon’s approvals.
3. Sync inventory and price
| What syncs | Direction | When |
|---|---|---|
| Inventory quantity | App → Amazon | On change + scheduled |
| Price | App → Amazon | On change + scheduled |
| Orders | Amazon → App | Short polling interval |
| Tracking / fulfillment | App → Amazon | When you ship |
💡 Tip: Inventory is keyed by SKU. If quantities look wrong on Amazon, the usual cause is a SKU mismatch between your catalog and the mapped listing.
4. Import Amazon orders
Amazon orders flow automatically into your unified Orders inbox, normalized to the standard order lifecycle.
5. Automate fulfillment (recommended)
- Create a flow triggered by Order paid, filtered to the Amazon channel.
- Add Push to ShipStation so paid Amazon orders route automatically. See ShipStation.
- When you ship, tracking pushes back to Amazon automatically.
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Channel shows “Disconnected” | Authorization expired | Reconnect from Channels → Amazon |
| Inventory not updating | SKU mismatch | Confirm catalog SKU matches the mapped listing |
| Listing rejected | Brand gating / missing attribute | Resolve gating in Seller Central; fill required attributes |
| Orders not importing | Sync paused / marketplace not selected | Check channel status |
