The two sides
Taboola by Realize
Connect your Taboola Backstage credentials in SignalBridge, create an event-based conversion in Taboola Realize for each SignalBridge event name you want (for example make_purchase), and install the SignalBridge script. When a visitor who arrived from a Taboola ad converts, SignalBridge sends a postback with the tblci click ID, the event name, revenue, currency and order ID.

Connect your Google account, choose a GA4 property and web data stream, and SignalBridge creates a Measurement Protocol secret named SignalBridge and starts sending events with GA4's recommended names, such as purchase, generate_lead and begin_checkout. Each event is sent once, with its value, currency and transaction ID. Server events are separate hits from the browser tag and are not joined to a browser session.
