Offline conversion tracking
HubSpot + ChatGPT Ads Integration
LeadTrackr sends HubSpot lifecycle-stage and deal-status changes to ChatGPT Ads through OpenAI’s Conversions API, matching each Closed Won deal back to its oppref click identifier so conversion-optimised bidding trains on customers instead of contacts.

From a HubSpot deal to a ChatGPT Ads conversion
HubSpot qualifies your leads — your team just works deals as usual.

|---|---|---|---|---|

| Bathroom — Sponsored | €1,200 | 52 | 11 | €11.8k |
| Broad — Home Reno | €900 | 96 | 5 | €4.2k |

How do you send HubSpot deals to ChatGPT Ads?
LeadTrackr reads the HubSpot lifecycle stage and deal status, then posts the matching outcome to the ChatGPT Ads Conversions API server-side. It captures the oppref click identifier when a visitor arrives from a sponsored ChatGPT placement, stores it as a property on the HubSpot contact together with hashed email and phone for advanced matching, and fires the conversion when the contact reaches Sales Qualified Lead or the deal is marked Closed Won — with the deal amount as its value.

How HubSpot + ChatGPT Ads works
Why connect them
What HubSpot + ChatGPT Ads unlocks
Built for conversions after the visit
A HubSpot deal that closes a month after the click is invisible to any browser pixel. LeadTrackr posts it server-side to the Conversions API, which is the layer OpenAI built precisely for outcomes that happen offline.
Deal amount as the training signal
ChatGPT Ads conversion events accept a value, so LeadTrackr sends the HubSpot deal amount with every Closed Won outcome. The oCPC auction weighs a large deal above a small one rather than counting every contact identically.
oppref stored as a contact property
The oppref identifier lives in an __oppref cookie for 30 days. Writing it onto the HubSpot contact at submission means a lifecycle change long after that window still resolves to the sponsored placement that earned the click.
Your HubSpot setup stays as it is
Qualification stays in HubSpot lifecycle stages and deal pipelines. LeadTrackr reads those signals and translates them into ChatGPT Ads conversions — no new workflow, no new property to maintain, no change to how your sales team works.
HubSpot teams connecting ChatGPT Ads early hand conversion bidding a Closed Won signal from day one, on a channel where most advertisers are still training the auction on form submissions.
How it works
Set up once, runs automatically
HubSpot lifecycle stage or deal status changes
A contact reaches Sales Qualified Lead, or a deal is marked Closed Won — the HubSpot moments you mapped as conversions, not the form fill that started them.
LeadTrackr builds the server-side event
LeadTrackr reads the oppref value from the HubSpot contact, adds the hashed email and phone for advanced matching, attaches the deal amount and stamps a stable event ID so the OAIQ pixel cannot double-count it.
Posted to the Conversions API
The event reaches your ChatGPT Ads Pixel ID over the server-side endpoint. OpenAI attributes it to the placement that earned the click and conversion bidding shifts toward the conversations that produce customers.
