Amazon Seller Central Integrations

Most-Used Amazon Integrations

The four pairs that drive the highest search volume and the most frequent ops team requests.

Amazon + Google Sheets

Connector required

For Amazon sellers without a dedicated BI tool, Google Sheets is the default reporting layer — but getting Amazon data there requires an automation tool because there is no native connection. The most common use case is a daily export of FBA inventory health metrics: units available, units reserved, sell-through rate, and stranded inventory count, all appended as time-stamped rows so ops teams can spot trends without logging into Seller Central. A second pattern uses order-level data: every new Amazon order creates a row in Sheets, giving finance a live feed for reconciliation before the bi-weekly settlement report arrives. Setup via Make typically takes 20–30 minutes using the Amazon module and a Google Sheets append-row action.

Amazon + Shopify

Native

When a brand sells on both Amazon and Shopify, inventory desynchronization is the most expensive recurring problem: an FBA sale that doesn't decrement Shopify inventory leads to overselling, cancelled orders, and negative reviews. Connecting Amazon Seller Central to Shopify via Make or n8n creates a real-time inventory bridge — every fulfilled Amazon order triggers a quantity adjustment on the matching Shopify variant, and new Shopify orders can optionally trigger an FBA fulfillment request. The integration also handles order-status sync, so customer-facing fulfillment emails in Shopify reflect the actual Amazon tracking number. Most teams use Make for this because its Amazon SP-API module handles the OAuth complexity; setup takes 45–90 minutes and requires matching SKUs across both platforms before enabling the sync.

Amazon + Xero

Native

Reconciling Amazon sales in Xero is the most time-consuming month-end task for small and mid-sized e-commerce sellers: Amazon pays out every two weeks via a settlement report that bundles product revenue, FBA fees, referral fees, refunds, and advertising charges into a single deposit. Without integration, the bookkeeper manually unpacks this into Xero line items — a 2–4 hour process per settlement. Connecting Amazon to Xero via a tool like Taxomate or a custom Make scenario automatically splits each settlement component into the correct Xero account, creates an invoice for sales, and records expenses for fees. The one-time setup of the account mapping takes more effort than a standard integration, but once live it eliminates the reconciliation burden entirely.

Amazon + Klaviyo

Connector required

Amazon's terms of service prevent sellers from directly emailing customers acquired through the marketplace — but every fulfilled order represents a buyer whose preferences and purchase behavior can inform smarter marketing on other channels. The integration pattern is to sync Amazon order data into Klaviyo as a custom property on a contact record, enabling segmentation by product category purchased, order frequency, and recency without violating Amazon's messaging rules. Sellers use this to build Klaviyo audiences of repeat Amazon buyers and target them via Meta or Google ads, or to suppress Amazon buyers from Klaviyo email flows that would duplicate Amazon's own transactional messages. Setup requires a middleware tool because there is no native Klaviyo-Amazon connector; Make's Amazon module combined with Klaviyo's profile API is the most common approach.

Common Amazon Integration Patterns

• – FBA Order Routing: Multi-channel sellers connect Amazon Seller Central to Shopify via Make or n8n so that FBA inventory levels update in real time — preventing overselling when the same SKU is listed on both channels.
• – Accounting Reconciliation: Finance teams sync Amazon settlement reports into Xero or QuickBooks to automatically categorize FBA fees, storage costs, refunds, and ad spend as separate line items — eliminating the month-end manual reconciliation sprint.
• – Post-Purchase Marketing: Ops and growth teams pipe Amazon order events into Klaviyo or Mailchimp to trigger review-request sequences, cross-sell flows, and lapsed-buyer win-back campaigns — data Amazon's own ecosystem won't surface natively.
• – Inventory Reporting in Sheets: Small seller teams export FBA inventory health data into Google Sheets on a schedule to track sell-through rate, stranded inventory, and reorder points without paying for a dedicated inventory management tool.

Amazon Integration Challenges

• – Amazon SP-API Access: Amazon's Selling Partner API requires a formal app registration and a multi-step OAuth flow — most no-code tools abstract this away, but initial setup takes longer than a typical connector and approval can take 24–72 hours.
• – Settlement Report Complexity: Amazon disburses funds every two weeks in a single lump sum. The settlement report contains 30+ line-item types (FBA fees, referral fees, reimbursements, ad charges) that must be mapped correctly or your Xero/QuickBooks reconciliation will show a single opaque transfer.
• – FBA vs MFN Inventory Separation: Sellers using both Fulfillment by Amazon and Merchant Fulfilled Network need to track two separate inventory pools. Many integration templates conflate them, causing stock-level errors in connected Shopify or WooCommerce stores.
• – Amazon's Restricted Data Policy: Customer PII (shipping addresses, email addresses) is masked or restricted in many API responses — you can sync order events and product data, but cannot build a direct contact list from Amazon buyers.

Before You Integrate Amazon

1. 1. Register Your SP-API Application: Create a Selling Partner API app in Seller Central's developer console before connecting any automation tool. You'll need your MWS credentials and a Developer Central account — allow 24 hours for Amazon's approval.
2. 2. Decide Your Inventory Source of Truth: If you sell on both Amazon and Shopify, decide which platform holds the master inventory count. Most sellers choose Shopify as source of truth and push quantity updates to Amazon — not the reverse — to avoid oversell risk.
3. 3. Map the Settlement Report Fields: Before connecting Amazon to Xero or QuickBooks, download one real settlement report and manually identify which line-item types map to which chart-of-accounts categories. Build this map into your integration before going live.
4. 4. Test with a Low-Volume SKU: Run your first automated sync against a single SKU with known, stable inventory. Confirm quantities, prices, and order statuses land correctly before enabling the full catalog.
5. 5. Set Up Sync Failure Alerts: Amazon's SP-API enforces rate limits and occasionally returns 503 errors during high-traffic periods. Configure Make or n8n to send a Slack or email alert on any failed scenario run — silent failures are the most common cause of inventory drift.

Amazon Integration FAQ

Does Amazon Seller Central have native integrations?

Amazon has native integrations with Shopify, Xero, QuickBooks, and Printify through its SP-API. Most other connections — like Google Sheets, Klaviyo, HubSpot, and Salesforce — require a connector tool such as Make or n8n because Amazon does not offer native connectors to those platforms.

How do I sync Amazon FBA orders to Google Sheets?

There is no native Amazon → Google Sheets connection. The most common approach is Make: create an Amazon module trigger (new order), map the FBA order fields to a Google Sheets append-row action. Setup takes 20–30 minutes. You get a live row per order — ideal for finance reconciliation before settlement reports arrive.

What is the hardest part of Amazon Seller Central integration?

SP-API approval. Amazon requires you to register a developer application in Seller Central before any third-party tool can access your order, inventory, or settlement data. Approval takes 24–72 hours and requires specifying which data roles your app needs. Without this step, no connector tool can authenticate.

How do I connect Amazon to Shopify to prevent overselling?

Shopify has a native Amazon sales channel that syncs inventory bi-directionally. For more control over which SKUs sync and how FBA vs MFN inventory is handled, use Make or n8n to build a custom sync with explicit inventory source-of-truth logic — typically Shopify as master.

How do I reconcile Amazon settlement reports with Xero or QuickBooks?

Settlement reports contain 30+ line-item types (FBA fees, referral fees, refunds, chargebacks). You need to map each fee type to the correct chart-of-accounts code in Xero or QuickBooks before building any automation. Xero has a native Amazon connection; QuickBooks typically requires Make. Map your categories first, then automate — don't automate and figure out the mapping later.

How do I send Amazon post-purchase emails via Klaviyo?

Amazon's Restricted Data Policy masks buyer email addresses in SP-API responses — you cannot export customer emails from Seller Central. The workaround is to trigger Klaviyo events from order data (order ID, SKU, order value) using Make or n8n, then match those events to profiles created at checkout if you also sell on your own storefront. Klaviyo's Amazon integration is designed for this multi-channel scenario where Shopify and Amazon share a customer base.

What is the difference between FBA and MFN inventory for integrations?

FBA (Fulfillment by Amazon) inventory is physically held in Amazon warehouses — Amazon ships it. MFN (Merchant Fulfilled Network) inventory is shipped by you directly. Most connector tools treat them as separate inventory pools. When syncing to Shopify or another storefront, you must decide which pool is your source of truth. Using FBA as the primary pool prevents overselling on Amazon but can cause your Shopify stock to appear lower than reality if you also ship MFN orders.
