Klar now supports full TikTok Shop data out of the box. Order data flows into Klar via your Shopify integration — when TikTok Shop is connected to your Shopify store, orders sync automatically. For ad spend, you need to connect TikTok as a separate data source in Klar.
tl;dr
Orders flow automatically: TikTok Shop → Shopify → Klar
Ad spend requires a separate TikTok connection in Klar (Store Configurator → Data Sources → TikTok)
For GMV Max campaign costs without the TikTok connection: manual import via the CMC sheet
How TikTok Shop data reaches Klar
TikTok Shop connects to your Shopify store via TikTok's official Shopify app. Once connected:
Order data — TikTok Shop orders (revenue, line items, returns) sync into Shopify and Klar picks them up automatically as part of your regular Shopify data sync. No separate connector needed.
Ad spend — ad spend does not come through Shopify. To get your TikTok campaign costs into Klar, you need to connect TikTok as its own data source (see below).
Connect TikTok as a data source in Klar
Go to Store Configurator → Data Sources → Add Data Source and select TikTok. Once connected, Klar pulls your TikTok campaign spend directly from TikTok Ads — so ROAS, channel performance, and your margin waterfall all include TikTok Shop costs.
⚠️ Without a TikTok data source connected in Klar, ad spend will not appear in your reports — even if the TikTok app is installed in Shopify.

Alternative: import TikTok Shop GMV Max costs manually
For TikTok Shop GMV Max campaigns where you don't have TikTok connected as a data source, you can import costs manually using the Custom Marketing Costs (CMC) sheet:
Go to Store Configurator → Data Sources → Add Data Source
Select CMC (Google Sheet for Custom Marketing Costs)
Enter your TikTok Shop campaign costs with the relevant date range, platform name, and amount
