If you cannot connect LinkedIn Ads to HubSpot with reliable attribution, you cannot scale confidently. HubSpot is where marketing and sales collaborate and revenue is measured.
Connecting LinkedIn Ads to HubSpot with Attry gives every Contact and Deal the right source, campaign, and creative so you can build reports that prove what creates customers.
How the connection works
Attry is a lightweight script you add to your site. It detects where a visitor came from, normalizes it into channels like Paid Social, Paid Search, Organic, and stores it in a cookie while they browse. On form submit, Attry writes the attribution into hidden fields so it flows into HubSpot.
If your HubSpot forms are embedded in cross-origin iframes, Attry loads a HubSpot specific adapter that patches hbspt.forms.createand injects attribution via onFormReady. The adapter is served from /api/integrations/hubspot/adapter and the source is inlib/attribution/hubspot-adapter.js.
