SignalBridgeThe two sides
TikTok Ads
Sign in to TikTok from SignalBridge and choose your Pixel, install the SignalBridge script or the Shopify app, then send a test event with your TikTok Test Events code. SignalBridge maps each event to a TikTok standard event, adds hashed customer data and ttclid, and delivers it with the same event ID as your browser Pixel so TikTok counts it once.

In Script Manager create a script with the location set to all pages, paste your SignalBridge snippet, and make sure the store uses Optimized One-Page Checkout so scripts can load on checkout and the order confirmation page. Connect your ad platforms, place a test order, and check that one Purchase appears with the right value. If the total is missing, send the order yourself with sb_track from an order confirmation script.
