How do I add Meta, Google Ads, and LinkedIn conversion tags in Head Tags?

Invoiced companies should connect the ad account in Console → Settings → Integrations instead of wiring every funnel step here. After connect, keep Head Tags for PageView / tag load on Meta, Google, and LinkedIn. ChatGPT ads has no Head Tags pixel: paste the Ads API key on Settings → Integrations → ChatGPT ads. If you have not connected Meta, Google, or LinkedIn, paste pixel snippets and JavaScript callbacks in Settings → Head Tags, then add a Custom HTML (HTML Script) element on the conversation node with an empty image whose onerror calls that function, for example report_conversion_interaction().
