To connect TikTok to Shopify, you need to follow these steps:

1. Install the TikTok Shopping app on your Shopify store. You can find this in the Shopify App Store.

2. After installation, open the app and click on "Connect account".

3. You'll be redirected to the TikTok For Business website. If you haven't created an account yet, you need to do so.

4. After creating your TikTok For Business account, you'll need to connect it to your Shopify store through the TikTok Shopping app.

5. Once you've connected the accounts, you can start creating product catalogs and tagging products in your TikTok videos and ads.

Remember that this connection will allow you to leverage TikTok's Shopping features, which includes showcasing your products directly on your TikTok profile, tagging products in your TikTok videos, and even creating shopping tabs.
