Amazon Multi-Channel Fulfillment (MCF) Integration

Connect Amazon Multi-Channel Fulfillment (MCF) with TikTok Shop in AfterShip Feed to auto-sync inventory, fulfill orders via Amazon FBA, and manage returns.

Written by Harneet Kaur

Plans: All plans Platforms: Amazon

Overview

AfterShip Feed enables you to list your Amazon products on TikTok Shop and seamlessly fulfill orders using Amazon FBA (Fulfillment by Amazon) by syncing orders to Amazon. This integration automates the process by generating fulfillment orders on Amazon when an order is placed on TikTok Shop. Once the Amazon FBA fulfillment order has tracking information, it will automatically fulfill the corresponding TikTok Shop order.

Prerequisites

Before using the TikTok Shop and Amazon FBA integration, it's important to keep note of certain limitations.

1. Amazon UK and US compatibility

This integration fully supports Amazon sellers from both the United Kingdom and the United States.

2. Orders and product syncing

  • AfterShip Feed supports both FBA and FBM (Fulfilled by Merchant) product syncing to your TikTok Shop

  • AfterShip Feed for TikTok Shop and Amazon FBA Integration only supports syncing orders that contain Amazon FBA products.

  • AfterShip Feed will block orders that contain FBM (Fulfilled by Merchant) products. Merchants have to manually fulfill FBM orders on the TikTok Seller Center

Please ensure that your products meet the necessary eligibility criteria set by Amazon for order fulfillment through their platform.

3. Understanding order status sync

The integration only syncs TikTok Shop orders with Awaiting shipment status to Amazon and subsequently a fulfillment order will be created on Amazon.

4. TikTok shipping option should be Shipped by Seller

AfterShip Feed only syncs orders with Shipped by Seller, also called the Seller shipping option on TikTok Shop. If you encounter syncing TikTok orders to Amazon, it could be due to the shipping option not being set to Shipped by Seller. You can modify the shipping option on TikTok Shop to resolve this issue. For additional assistance and troubleshooting, watch the demo video here.


​Note: Warehouse addresses in TikTok Seller Center
​

Shipped by Seller requires both a pickup warehouse address and a return warehouse address. To add them, go to My Account > Account Settings > Warehouse Settings in TikTok Seller Center.

  • Pickup warehouse address: If you're a US seller, you can enter the address Amazon MCF recommends: Amazon Fulfillment Center CMH2, 6050 Gateway Ct, Groveport, OH 43125. If you're a UK seller, you can enter a centrally located Amazon fulfillment center in your region.

  • Return warehouse address: Enter your own warehouse or business address. If you don't use AfterShip Feed's MCF return integration, buyers send their returns to this address, so make sure you can receive packages there. If you use the MCF return integration, see Step 5.
    ​

5. Inventory sync reflects available (FBA) stock only

AfterShip Feed syncs only your Available (FBA) inventory to TikTok Shop. The following inventory types are not included in the sync:

  • FC transfer (part of On-hand): units currently moving between Amazon fulfillment centers

  • Inbound: inventory currently in transit to Amazon fulfillment centers

  • Unfulfillable: inventory marked as unsellable (for example, damaged or non-compliant items)

  • Reserved: inventory reserved for pending shipments or fulfillment center transfers

As a result, the inventory quantity displayed on TikTok Shop reflects only your Available FBA stock and may be lower than your total inventory shown in Amazon Seller Central.

This is expected behavior. If you notice a difference between Amazon and TikTok Shop inventory levels, it does not indicate a sync issue.

How to use AfterShip Feed for TikTok Shop and Amazon FBA Integration

Step 1: Install AfterShip Feed for Amazon

  1. Go to Apps and Services in your TikTok Shop Seller Center admin

  2. Click on App and Service Store

  3. Search for AfterShip Feed for Amazon and Install the service.

  4. Select the TikTok store, set the authorization duration, input the contact email, and phone number (optional). Select the confirmation checkbox and click Confirm to install

Or,

Connect TikTok Shop to Amazon on AfterShip Feed admin by directly connecting your Amazon store while setting up the AfterShip Feed account.

Step 2: Sync Amazon products to TikTok Shop

Once your Amazon Seller account is connected to AfterShip Feed, it’s time to sync and map your products to TikTok Shop via AfterShip Feed.

For more information on product syncing and mapping, check out this help guide.

Step 3: Sync orders and manage fulfillment

  1. Once your Amazon (FBA) products are synced to TikTok Shop (Shipped by Seller), any FBA orders placed on TikTok Shop will be synced to Amazon via AfterShip Feed.

    If order synchronization fails due to unexpected reasons, we kindly advise you to check the AfterShip Feed Order Center for detailed reasons and follow the instructions to resolve the mentioned issue to protect your revenue and fulfill your TikTok orders successfully.

  2. A fulfillment order along with the tracking number and shipping service will be created in Amazon.

  3. AfterShip Feed will sync the order fulfillment details to TikTok Shop

Step 4: Track Amazon fulfillment order status

You can conveniently check the status of your fulfillment orders on Amazon. Simply access your Amazon Seller Central account and navigate to Manage orders> Search order ID.

Step 5: Return TikTok products back to MCF warehouse

Available for TikTok US merchants only.

Before enabling return and refund sync, make sure the following are in place:

1. Connect a shipping carrier account: Since Amazon MCF does not handle return logistics directly, you'll need a shipping carrier account connected to AfterShip Feed to generate return shipping labels. Check the list of supported carriers below.

  • If you want additional carriers to be supported to generate returns shipping label, reach out to our customer support for assistance.

2. Configure your TikTok Shipping method: Your TikTok shipping method must be set to Seller Shipping (also referred to as Ship by Seller) for returns to work correctly.

Important: Whitelisting for MCF returns (Beta)
​

MCF returns is in Beta. You need two whitelisting approvals before you can turn on return and refund sync:

  • AfterShip whitelisting: Contact our customer support team to whitelist your AfterShip organization.

  • TikTok Shop whitelisting: Contact your TikTok Shop Account Manager to whitelist your account, and provide your Shop code or Shop ID. Follow up with your Account Manager to check the status.

Before any whitelisting is complete, you can:

  • Add your pickup and return warehouse addresses in TikTok Seller Center (see the note under Prerequisite 4). This step doesn't require whitelisting. You can't publish products on TikTok Shop until you add a return warehouse address, so we recommend doing this first.

  • Connect your Amazon store and TikTok Shop to AfterShip Feed (Step 1).

  • Sync and publish your products to TikTok Shop (Step 2).

After AfterShip whitelists your organization (even if TikTok Shop whitelisting is still pending), you can:

  • Set up your return shipping carrier account in AfterShip Feed.

After both AfterShip and TikTok Shop whitelist you, you can:

  • Turn on Auto-sync returns and refunds in AfterShip Feed.

What to enter as your return warehouse address
​

When return and refund sync is turned on, AfterShip Feed generates each return label using the warehouse address Amazon assigns to that return. This sends each return to the Amazon return warehouse assigned to it. TikTok Seller Center uses your stored return address only as a fallback if a system error occurs, so we recommend entering your own address.

Enabling return and refund sync in AfterShip Feed

  1. Navigate to AfterShip Feed Settings, then Channel settings.

  2. Go to the Return and refund sync settings and toggle the feature on the Auto-sync returns and refunds option.

  3. Under Add Shipping Carrier, select the carrier account you’d like to use for generating return labels. All the carrier accounts your organization is currently connected to and that AfterShip Feed supports will be listed for selection.

  • Select the carrier and click Add carrier.

  • If you want to add more carrier accounts, click Add carrier accounts.

Only one carrier account can be used at a time.

Click Save.

How the return process works

  1. Buyer requests a return from the TikTok App.

  2. AfterShip syncs the TikTok return order to Amazon when the request passes the first approval (according to TikTok policy, almost all products should be returnable; only several product categories need to be manually approved/rejected) and creates an MCF RMA.

  3. Amazon MCF returns an MCF shipping slip and warehouse address to AfterShip.

  4. AfterShip creates a shipping label using the information from the seller's carrier account, and combines the shipping label, MCF slip, and order information into one file and passes the file to the TikTok App.

    • Since different carriers have different address format requirements, pay attention to whether the shipping label is successfully generated during testing.

  5. Buyers access the file from the TikTok App and ship the products back to the MCF warehouse.

  6. AfterShip will track the return tracking number. If the package is confirmed as delivered, a TikTok refund will be triggered. This means the second approval of this TikTok return request will be auto-triggered.

  7. Buyer receives the refund notification sent by TikTok Shop.

FAQs

1. What happens after TikTok Shop whitelists my shop for MCF returns?

You don't need to change anything in TikTok Seller Center. After TikTok Shop whitelists your shop:

  • Buyers no longer see TikTok Shop's standard return shipping options. Returns use the return carrier of your choice instead.

  • When a buyer submits a return request, AfterShip Feed picks up the new return, gets the return label from Amazon MCF, and uploads it to TikTok Shop.

  • Buyers can see the return label in the TikTok Shop app after they submit the return.

For this to work, make sure your Amazon store is connected to AfterShip Feed and Auto-sync returns and refunds is turned on.
