Server-Side Conversion API (CAPI)

Ad blockers and browser privacy changes are killing your conversion tracking. Client-side pixels miss up to 30% of conversions, leaving you with incomplete data and wasted ad spend. Astrocart's server-side Conversion API (CAPI) sends purchase and event data directly from your server to advertising platforms — bypassing ad blockers entirely. Support for Google Ads, Meta (Facebook/Instagram), and TikTok Ads is built in. Every purchase, add-to-cart, and checkout event is sent server-side with full attribution data. Your advertising platforms see the complete picture, leading to better optimisation and lower cost per acquisition. All CAPI events are GDPR-compliant with consent-gated firing. Events only fire for visitors who have given marketing consent via your cookie banner. No consent, no tracking — fully automatic.
