Please note that:  Our integration now supports TikTok Shop US, catering exclusively to shipping within the United States.

I. Registering for TikTok Shop US

Begin by creating an account on the TikTok Seller Center. US merchants should visit TikTok Seller US.

Follow the step-by-step guide provided here for detailed instructions.

Complete the registration by clicking “Submit". TikTok may take 1-2 days to review your account. Once approved, you can proceed to set up your TikTok Shop and link it with Merchize.

II. Select a Shipping Option for your TikTok Shop

TikTok Shop US provides two shipping options, “Shipping by TikTok” and “Shipping by Seller”. Merchize currently supports both options for our fulfillment orders.

  • TikTok Shipping: Merchize will print orders and prepare your packages. Afterward, the designated carrier will collect the package and deliver it to your customers. With this option, sellers will be eligible for Seller compensation for any logistic issues. TikTok will also handle any issues regarding logistics and cover the cost of the package in case of Returns.
  • Seller Shipping: Merchize will handle fulfillment and shipping for your orders on your behalf.
    In the shipping settings of your TikTok Shop US, as illustrated below, you can choose either “Shipping by TikTok” or “Shipping by Seller”.

III. How to Process TikTok Shop orders with Merchize

1. For Seller Shipping orders

You can fulfill TikTok orders with Seller Shipping option by one of the following methods:

(1) Automatically synchronize TikTok orders by integrating your TikTok Shop account with Merchize

(2) Create manual orders in Merchize

(3) Import orders via CSV file

(4) Automate order using API

With (2), (3), and (4), the fulfillment process of TikTok’s Seller Shipping orders is essentially similar to regular orders. Note that “tiktok" tag must be added to differentiate TikTok Seller Shipping orders from other fulfillment options. 

How to automate Automatically synchronize Seller Shipping orders

To link your Merchize account with your TikTok shop, visit the TikTok channel integration page. 

On the integration page:

  • Tick the box indicating agreement with the documentation and click “Connect".
  • You’ll be redirected to TikTok. Choose “North America seller” as your account type to initiate authorization.

  • In the “Duration” dropdown, select “Unlimited”. Ensure you check the box next to “By clicking confirm…” and then click “Confirm to install”.

  • Click on “Authorize".

  • You may need to wait until the authorization process is complete and the screen redirects to the TikTok integration page on Merchize.
  • Your TikTok shop should now be connected to Merchize. The “Accounts connected" column will display your account as active.

Once your TikTok account is linked with Merchize and you select Seller Shipping for your TikTok Shop, the system will automatically synchronize all orders labeled as “Awaiting shipment."

  • To see all TikTok orders using the Seller Shipping option, from the Order import log page, select “TikTok” from the “Source” dropdown.

Any errored orders will be listed under the Failed tab, along with an error message.

  • To proceed with fulfillment for your Seller shipping orders, navigate to your order detail page and upload the print file to each order item.

Merchize will automatically process and update the tracking information for the orders in your TikTok store.

(Your “order history" keeps track of all transaction and processing activity for an order, with status updates along the way.)

Product details will also be synchronized with your Merchize store.

You have the option to fulfill the entire order or parts of it, and include branding labels and other packaging customizations.


2. For TikTok Shipping orders

Currently, Merchize only supports manually importing fulfillment order details into Merchize using a CSV file. 

Note: A label handling fee of $0.5 will be charged for each TikTok Shipping label.

Compulsory fields must be filled in for each order item (exclusively for TikTok Shipping order importer):

  • label: The image link to shipping label provided by TikTok. The only accepted format for label files is PDF.
  • tracking number: The tracking number of orders provided by TikTok.
  • Merchize warehouse:  The location of selected Merchize warehouse. Merchize currently has two warehouses in two locations, which are California and New Jersey. So, “CA" and “NJ" are the only two accepted values in this column.

Other required fields for CSV files include mockUpFront, mockUpback (and such), designFront/ designBack (and such), type, title, size, color, orderNumber, quantity. For more details about each field on the CSV file, you can read our guidelines on how to import orders to Merchize manually.
