SignalBridgeThe two sides
Facebook Ads
Connect your Meta ad account and dataset (Pixel) in SignalBridge, then install the SignalBridge script or the Shopify app. Each supported event goes to the Conversions API with a shared event ID, hashed customer details and your fbc and fbp identifiers. Meta merges it with the browser event when both arrive. Events from visitors who have not agreed to marketing tracking are not sent.

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.
