# Sync fulfillment

{% hint style="info" %}
The fulfillment sync feature is currently available for **US** TikTok Shop **only**.

If you use **other** connector apps with TikTok Shop, we recommend using **only** our app for product and order sync to **prevent duplicate syncing**.
{% endhint %}

Here’s how EcomSend Connector synchronizes fulfillments:

#### Fetching **fulfillment info**

Under fulfillment type-fulfilled by seller, there are **two shipping types**:

* **Seller shipping (SELLER):** Also called *shipped via seller*. Sellers manage shipping through their own channels (e.g., Shopify).
  \*

  ```

  ```
* **TikTok shipping (TIKTOK):** Also called *platform shipping* or *shipped via platform*. Sellers purchase shipping labels through TikTok Shop and either schedule a pick-up by a TikTok Shop carrier or drop off parcels at a TikTok Shop carrier location.
  \*

  ```

  ```

**How fulfillment info is fetched:**

* **Seller shipping:** Fulfillment info is synced from **Shopify to TikTok Shop**. When an order is fulfilled in Shopify, our app automatically fetches the fulfillment information.
* **TikTok shipping:** Fulfillment info is synced from **TikTok Shop to Shopify**. When an order is fulfilled in TikTok Shop, our app automatically fetches the fulfillment information.

#### Syncing fulfillment

* **Seller shipping:** Sync fulfillment info (tracking number, carrier, and other details) **from Shopify to TikTok Shop** based on your settings.

  ```

Sync options:

* **Manual sync:** On the ***Orders page*** in our app, find the order you want to sync and click the **Sync** button in the **Action** column. Or **select multiple orders** to **sync in bulk**.
  \*

  ```
  <figure><img src="/files/3fkp8y8H1YA1aO2JAuNH" alt=""><figcaption></figcaption></figure>
  ```
* **Automatic sync:** **Enable** the *Automatic Sync* feature under ***Settings → Orders → Fulfillment***. The system will automatically sync all 'Not synced' fulfillment information (existing and new).
  \*

## Field mapping details <a href="#field-mapping-details-shopify-tiktok-shop" id="field-mapping-details-shopify-tiktok-shop"></a>

The following section explains in detail how the main fields are synced.

> **TikTok Shop**: Go to TikTok Shop Seller Center Admin → Orders page → Manage Orders → Select specific order to see details

### **Seller shipping**

Sync fulfillment info **from Shopify to TikTok Shop.**

When fulfilling orders in Shopify, you can choose your own shipping carrier. However, the following criteria must be met:

1. The carrier **must** be from the approved list of [**TikTok Shop's Integrated Carriers**](https://seller-us.tiktok.com/university/essay?knowledge_id=8308896260065025\&role=1\&course_type=1\&from=search%7BcontentIdParams%7D\&identity=1#EB7F00D0)**.**
2. A valid, traceable **tracking ID** must be uploaded to the Seller Center for all dispatched orders.

> TikTok Shop currently supports tracking for **integrated carriers only**. Since shipping service names can vary across platforms, we provide a **carrier name mapping** feature to minimize mismatches.
>
> Different carriers use different tracking number formats, so to ensure successful order syncing, make sure your **tracking numbers match the format required** by the corresponding TikTok Shop shipping provider.

#### Tracking number → Tracking ID, Carrier → Shipping provider
