# Link products

Syncing an order to Shopify **requires a corresponding item** in Shopify. If the item was not previously synced via EcomSend Connector, it cannot be automatically matched, which may cause the order sync to fail.

Don’t worry! EcomSend Connector provides a **Link Product** feature that allows you to link the order item to the existing Shopify product.

## What does Link Product mean?

When two products are linked, our app treats them as the same product. For example, if you link **TikTok Shop product A** to **Shopify product C**, the following will happen:

* When an order containing **product A** is generated on TikTok Shop and synced to Shopify, our app will create a corresponding order using **product C** in Shopify and deduct the inventory of **product C** accordingly.

## How does the Link Product feature work?

If there are **unlinked products** in your store, a **Link product** button will appear in the top-right corner of the **Orders** page. Clicking it will take you to the Link products page.

On this page, EcomSend Connector lists products from existing synced orders that were **not originally synced** via EcomSend Connector to TikTok Shop.

There are two ways to link products:

1. **Auto-link same products:** Automatically link products between TikTok Shop and Shopify that share the same SKU.
2. **Manual link:** Link each product manually based on your requirements.

#### Auto-link same products

If the products to be linked share the same SKU as existing Shopify products, an **Auto-link same products** button will appear in the top-right corner.

1. Click **Auto-link same products** → A popup appears showing the corresponding products.
2. Verify that the products match your expectations.
3. Click **Auto-link** → The system will automatically link the products.
4. After linking, you can see the updated link status in the list.

> To unlink a product, click the **Unlink** button in the **Action** column.
