What does the HubSpot LinkedIn Ads integration do?
It connects LinkedIn ad accounts to HubSpot's ads tool. Lead Gen Form leads sync into HubSpot contacts, ads are tracked and reported in HubSpot, contact and company segments become LinkedIn matched audiences, and lifecycle stage changes can be sent back through LinkedIn's Conversions API so campaigns optimize for qualified leads, not just form fills.
This guide follows HubSpot's and LinkedIn's documentation as of October 2026. Permissions are the most common blocker, so they come first.
What do you need to connect LinkedIn Ads to HubSpot?
An Account Manager role on the LinkedIn ad account, and a role on the LinkedIn Page, such as super admin, content admin or Lead Gen Forms manager, to sync leads. An ad account role doesn't grant Page permissions. In HubSpot you need ads publishing permission. Accounts on hold can't connect, and HubSpot reports the most recent year of data.
- Lead forms must include email as a required field.
- Plans: connecting, tracking and lead syncing work on all HubSpot plans; contact-segment audiences need Marketing Hub Starter or above.
How do LinkedIn Lead Gen Form leads reach HubSpot?
Once the ad account and Page are connected and lead syncing is on, leads from the account's Lead Gen Forms sync into HubSpot as form submissions on contacts. You can bring in the last 90 days plus new leads. Leads from any ad type sync, even ad types HubSpot can't track, such as message ads.
Custom questions become text properties in HubSpot. If you connected before LinkedIn's newer lead sync, reauthorize the account so leads keep flowing.
How do HubSpot audiences work on LinkedIn?
HubSpot sends contact details from segments, or company details from target accounts and tiers, to LinkedIn's matched audiences. LinkedIn needs at least 300 rows and 300 matched members, can take up to 48 hours to build an audience, and only matches opted-in members in the EEA. LinkedIn ended lookalike audiences in February 2024, including through HubSpot.
Company audiences suit account-based campaigns: build target accounts and tiers in HubSpot, then sync them so LinkedIn shows ads to people at those companies.
How do you send HubSpot conversions to LinkedIn?
Create conversion events in HubSpot triggered by lifecycle stage changes, such as becoming a marketing or sales qualified lead. HubSpot sends hashed email and other details with the LinkedIn click or lead ID, and LinkedIn maps both qualified stages to its qualified lead type. LinkedIn accepts events from the last 90 days and deletes the data after 180.

HubSpot says conversion events need Marketing Hub Starter or above; LinkedIn's page says its HubSpot connection is for Professional and Enterprise, so confirm in your account. Qualified-lead data should reach LinkedIn within 30 days to help optimization. Our lead scoring guide helps define what qualified means.

What happens if you disconnect LinkedIn Ads?
HubSpot keeps your data and uninstalls the LinkedIn Insight Tag it added. Audiences stop syncing. Leads submitted while disconnected still sync after you reconnect, but they won't appear in HubSpot's attribution reports. If you're leaving HubSpot's ads tool, remove its tracking parameters from your ads.

Key takeaway: Get both the ad account and Page roles right, sync Lead Gen Forms, use company audiences for target accounts, and send qualified stages back so LinkedIn optimizes for pipeline.

HubSpot's documentation says conversion events need Marketing Hub Starter or above, with five events on Starter. LinkedIn's own page says its HubSpot Conversions API link is for Marketing Hub Professional and Enterprise. Check your account before planning around Starter.
