Amazon Integration Guide

Purpose

This guide provides step-by-step instructions for connecting your Amazon Seller Central account to EFS for both merchant fulfillment (orders shipped by EFS) and FBA prep services (preparing inventory for Amazon FBA).

1. Before You Begin

  • Active Amazon Seller Central account
  • Professional seller account (required for API access)
  • Admin access to authorize API connection

Important: If you don’t have Integration Portal credentials, contact your Client Care Account Specialist before proceeding.

2. Understanding Amazon Integration Types

EFS offers two types of Amazon services:

Merchant Fulfillment (MFN)

  • EFS fulfills orders placed on Amazon directly to customers
  • You remain the merchant of record
  • Orders sync automatically from Amazon to EFS
  • Tracking updates sent back to Amazon
  • Inventory levels can sync to prevent overselling

FBA Prep Services

  • EFS prepares your inventory for shipment to Amazon FBA warehouses
  • Services include labeling, poly bagging, bundling, case packing
  • You create shipments in Amazon Seller Central
  • You place prep orders in FCP
  • EFS ships prepared inventory to Amazon fulfillment centers

This guide covers both services. Follow the sections relevant to your needs.

3. Setting Up Merchant Fulfillment Integration

Step 1: Access Integration Portal

  1. Log into the Integration Portal at https://integration.efulfillmentservice.com
  2. Navigate to the Integrations tab
  3. Click the blue “+ Add” button in the upper right

Step 2: Select Amazon

  1. From the dropdown menu, select Amazon
  2. The Amazon integration configuration page will appear

Step 3: Configure Basic Settings

Fill out the following fields:

Integration Name:

  • Enter a one-word name (letters and numbers only, no spaces)
  • Example: “AmazonUS” or “AmazonStore”
  • Helps identify the integration if you have multiple

WMS Target:

  • Should auto-populate with “FcpLive”
  • If you have multiple warehouses, select the appropriate one

Order Sync Schedule:

  • How often we check for new orders (recommended: Every 30 minutes)
  • Select from dropdown

Inventory Sync Schedule:

  • How often we update Amazon inventory (recommended: Hourly or Every 2 hours)
  • Select from dropdown

MWS Auth Token:

  • Leave blank (legacy field, not used)

LWA Refresh Token Expiration:

  • Leave blank (auto-populated after OAuth)

Marketplace Region:

  • Select your marketplace:
    • North America (US, Canada, Mexico)
    • Europe (UK, Germany, France, Italy, Spain, etc.)
    • Far East (Japan, Australia, etc.)
  • You need a separate integration for each region

Fulfillment Latency:

  • Number of days to fulfill orders after they’re placed
  • Recommended: 2-3 days
  • This tells Amazon how long before tracking will be uploaded
  • Accounts for time between order placement and EFS receipt

Important: Setting this too low (1 day) may cause late shipment issues. EFS ships within 1 business day after we receive the order, but there’s delay between placement and our receipt.

Remote Fulfillment with FBA:

  • Select Yes if you use Amazon’s remote fulfillment feature
  • Select No if you don’t (most common)
  • Choosing incorrectly will cause integration issues

Step 4: Save Integration

Click the blue “Save Integration” button at the bottom of the page.

Important: Do NOT close the window. You’ll be automatically redirected to Amazon for authorization.

Step 5: Authorize Amazon Access (OAuth)

  1. You’ll be redirected to Amazon Seller Central login
  2. Log in with your Amazon Seller Central credentials
  3. Amazon will show the permissions EFS is requesting:
    • Read order information
    • Update order status
    • Access inventory data
    • Upload tracking numbers
  4. Check the box to acknowledge the permissions
  5. Click “Confirm”

You’ll be redirected back to the Integration Portal.

Step 6: Verify Connection

After redirect, verify the following fields are now populated:

  • Marketplace ID

4. Testing the Amazon Integration

Step 1: Refresh Cart Items

  1. In Integration Portal, go to your Amazon integration
  2. Click “Cart Items”
  3. Click the blue “Refresh Cart Items” button

Important: Amazon does NOT provide a product list through the API. You must manually add SKUs you want to sync.

Step 2: Add Custom Cart Items

For each product you want EFS to fulfill:

  1. Click “+ Add Custom Item”
  2. Fill out the form:
    • Item Name: Product description (for your reference)
    • Item SKU: Must match EXACTLY as listed in Amazon
    • Declared Value: Leave blank
  3. Click “+ Add”

SKU Matching:

  • Use Amazon’s “Seller SKU” (not ASIN)
  • Found in: Seller Central → Inventory → Manage Inventory
  • Must match FCP SKU or create SKU mapping

Tip: For multiple products, contact your Client Care Account Specialist for bulk upload assistance.

Step 3: Create a Test Order

  1. In Amazon Seller Central, create a test order
  2. Use Amazon’s “Test Order” feature or place a real order
  3. Ensure the product SKU is in your FCP inventory
  4. Wait for next sync cycle (up to 30 minutes)

Step 4: Check Received Orders

  1. In Integration Portal, go to your Amazon integration
  2. Click “Received Orders”
  3. Look for your test order

Success indicators:

  • Order appears with status “NEW” or “ACCEPTED”
  • Order details are correct (address, SKU, quantity)

Step 5: Verify Order in FCP

  1. Log into your Fulfillment Control Panel
  2. Go to Orders → Search/Edit Orders
  3. Search for the test order

Success: Order appears as “Pending” (yellow box) and ready for fulfillment

5. Setting Up Inventory Sync

Amazon inventory syncing prevents overselling by updating Amazon with your available FCP inventory.

Step 1: Activate Products for Sync

  1. In Integration Portal, go to Cart Items
  2. Find products you want to sync
  3. Click the green “Play” button in the Options column
  4. Status changes to “ACTIVE”

Only activate products you want synced. Unactivated products won’t have inventory updated.

Step 2: Set Sync Schedule

  1. Go to your Amazon integration main page
  2. Verify Inventory Sync Schedule is set appropriately
  3. Recommended: Hourly or Every 2 hours
  4. Save if you made changes

Step 3: Enable Inventory Sync

  2. Switch to ON (blue)

Step 4: Monitor First Sync

Wait for the next sync cycle, then:

  1. Go to Amazon Seller Central
  2. Navigate to Inventory → Manage Inventory
  3. Verify quantities match your FCP inventory
  4. Check that quantity updates when you adjust FCP inventory

Note: Syncing updates the Fulfillment Latency setting on a SKU-by-SKU basis. Changes to Fulfillment Latency only apply when inventory syncs.

6. Configuring Ship Method Mappings

Amazon uses standardized shipping service levels that need to be mapped to EFS shipping codes.

Step 1: Access Ship Maps

  1. In Integration Portal, go to your Amazon integration
  2. Click “Ship Maps” in the navigation

Step 2: Create Standard Mappings

Amazon typically uses these shipping methods:

Expedited 3DAY 3-day express
NextDay OVERNIGHT Next day delivery
SecondDay 2DAY 2-day delivery

For International Orders:

Amazon Method EFS Shipping Code Purpose
International INTERNATIONAL_DEFAULT Standard international
IntlExpress INTERNATIONAL_PRIORITY Express international

Step 3: Create Each Mapping

For each method:

  1. Click “+ New Ship Map”
  2. Cart Method: Enter Amazon’s method name exactly (case-sensitive)
  3. WMS Shipping Code: Select appropriate EFS code from dropdown
  4. Signature Required: Check if needed (typically only for high-value)
  5. Click “Save”

Repeat for all methods used in your Amazon store.

Tip: Use “Best Rate Economy Lightweight Post” for Standard method to enable rate shopping and save on shipping costs.

7. Enabling Order Sync

Once testing is successful, enable automatic order syncing.

Step 1: Turn On Order Sync

  1. Go to your Amazon integration main page in IS2
  2. Find the Order Sync toggle

Step 3: Verify Tracking Updates

  1. Wait 4-6 hours after an order ships
  2. Check Amazon Seller Central → Orders
  3. Verify tracking number appears
  4. Confirm order status updated to “Shipped”

Tracking updates occur:

  • Approximately 4 hours after order ships
  • Multiple times per day (every 30 minutes at :20 and :50)
