You have to set categories and attributes (specifics) for your Magento products when adding them to M2E TikTok Shop (TTS) Listing. Products without the category and related attributes can’t be listed on TikTok Shop.
By providing this information, you can ensure your products are accurately categorized and described. This also helps enhance product visibility and appeal on TikTok Shop.
Assign categories #
Once you’ve selected products to be added to your M2E TTS Listing, you will need to assign them to the appropriate category. For that, choose the preferred category settings first.

All Products same Category #
The same category settings will be applied to all products in M2E TTS Listing. Click the Edit button to start assigning the TikTok Shop category to your products.

You can choose from the previously saved categories or browse through the category tree to find the most suitable one.

When choosing a category, you can select a TikTok Shop category automatically suggested based on the product title. The suggestion appears in the Recommended Categories tab:

Confirm your choice to proceed.
Set Manually for each Product #
Set a relevant TikTok Shop category manually for each of the selected products.

Click Edit Category to assign the corresponding TikTok Shop category to your product. You can choose from the previously saved categories or browse through the category tree to find the most suitable one.
A TikTok Shop category is suggested based on the product title when setting a category. You can review it in the Recommended Categories tab:

Confirm your choice to proceed.
Assign attributes #
Once the category is set, you should assign product attributes (specifics) per category. Attributes define such product details as size, color, brand, style, etc., and help customers make informed purchasing decisions.
Click Edit to start assigning the attributes.

In the Mode section, select one of the available options from the drop-down menu:
- Custom Attribute – select a Magento Attribute that contains an appropriate value.
- Custom Value – manually enter the relevant value for the attribute.

TikTok Shop category attributes allow you to provide GPSR compliance files, images, and required product certificates for your European listings.

You can either select a Magento attribute to automatically pull the relevant data or enter a custom value, such as a direct link to an image or certificate. There is also an option to add multiple values if needed.
Product data validation #
TikTok Shop assigns specific attributes to each product category, so your product data must match these to ensure proper classification and visibility. M2E TikTok Shop Connect automatically validates this data whenever you assign or edit a Category for a not listed product in a Listing.
The system checks that Magento attributes mapped to TikTok Shop fields meet format, data type, and value requirements. For example, if a category requires a specific size, the value must fall within TikTok Shop’s accepted range. Any validation errors must be fixed by updating or adding the correct attributes.

After successful validation, M2E TikTok Shop Connect submits the data to TikTok Shop, where it’s reviewed before listing. Additional adjustments may be needed during this review.
Edit categories and specifics #
At any time, you can modify category and attribute settings for your TikTok Shop products. All assigned categories are located under Configuration > Categories.
To edit TikTok Shop category attributes, click Edit next to the relevant category.

⚠️ Any changes made to category data will be automatically applied to all TikTok Shop products using that category.
If you need to modify category attributes for specific products:
- Navigate to your M2E TikTok Shop Listing.
- Switch to Settings View Mode (located at the top of the grid).
- Select the products you want to update.
- Click Edit Category Settings > Categories & Specifics to adjust the attributes.

This allows you to refine category settings for individual listings without affecting all products assigned to the same category.
ℹ️ If your products are listed on TikTok Shop, the extension will send the category and attribute changes to the marketplace based on the Revise Rules in your Synchronization Policy.
