How Server-to-Server Tracking Works
Server-to-server tracking eliminates browser-based tracking issues by sending conversion data directly between servers. This increases reliability, improves attribution accuracy, and reduces data loss caused by ad blockers or browser restrictions.
Create a Conversion Goal in the Dashboard
Log in to your advertiser panel and configure your conversion goals:
Configure Conversion Goals →Append the Tracking Token to Your Landing Page
When a user clicks your ad, a unique tracking ID is generated and passed to your page.
https://yourdomain.com/?tracker={conversions_tracking}Store the Unique Conversion ID
Save the token in a session variable, cookie, or database so it can be used when the conversion occurs.
Send the Postback Request
Fire the postback URL when a conversion event occurs on your server:
https://YOUR_TRACKING_DOMAIN/tag.php?goal=GOAL_ID&tag={conversions_tracking}&value={conversion_value}For dynamic CPA campaigns, append:
