This article provides sellers with details on how they can use the auto combine orders feature to group multiple orders from a buyer into one package in Shopify.
Note: This only applies to sellers who use the "Shipped by Seller" option.

How does it work

You can now streamline your shipping with the Auto Combined Orders feature. Once enabled, it will automatically sync TikTok Shop’s recommended order groupings to Shopify, allowing you to instantly see which packages to combine, therefore saving you valuable fulfillment time and cutting down on shipping fees.

1. To enable this, first go to: Seller Centre > Logistics > Shipping > Automated order combination
   

Automated Order Syncing

• A customer places multiple eligible orders on TikTok Shop.
• TikTok Shop automatically groups these orders together and assigns a unique Group ID.
• When the orders sync to Shopify via the TikTok app, this Group ID is automatically added to the Notes section of each corresponding order.

Identification & Fulfillment

• Have your fulfillment team check the order Notes in Shopify to spot orders with matching Group IDs that need to be packed together.
• Fulfill each of the grouped orders directly within Shopify (or through your integrated ERP/OMS system).

Add Tracking & Sync

• Enter the exact same tracking number and carrier information for every Shopify order that belongs to that combined package.
• Once the tracking is saved in Shopify, the TikTok Shop app will automatically sync the data back to TikTok Shop, marking all the grouped orders as fulfilled.
  

How to view it in Shopify Admin

To check whether an order contains the grouping signal in Shopify Admin:

1. Go to Shopify Admin.
2. Open Orders.
3. Click the target order.
4. Scroll to Additional Details.
5. Look for the entry that contains auto_combine_group_id.
