Create and sync ad conversion events with ChatGPT

Last updated: September 15, 2026

Available with any of the following subscriptions, except where noted:

After connecting your ChatGPT Ads account to HubSpot, you can create ad conversion events to send conversion data from your HubSpot CRM back to ChatGPT. HubSpot sends conversion signals when a contact's lifecycle stage changes or a form is submitted. ChatGPT uses this data to optimize ad targeting over time.

You can also create and sync ad conversion events with your Google Ads account, Meta Ads accounts, LinkedIn Ads account, or TikTok account.

Permissions required Ads publishing permissions are required to connect your ad accounts. If this permission is granted through a permission set, update that permission set to include Ads publishing.

Please note: if you're a Super Admin, you can opt your account into the ChatGPT Ads in HubSpot beta.

Before you get started

Understand requirements

  • Your ChatGPT Ads account must be connected to HubSpot before you can create conversion events. 
  • Before creating a conversion event, make sure each contact whose data you plan to share with ChatGPT Ads has given permission for their data to be shared.

Understand limitations & considerations

  • Only updates to records that occur after creating the conversion event in HubSpot will be counted and used to optimize ad delivery.
  • When a ChatGPT conversion event is synced, HubSpot will send the ChatGPT click ID to ChatGPT and any of the optionally chosen fields: email address, first name, last name, phone number, IP address, city, state, zip code, and country.
