To configure lead syncing for your Google Ads account:
In your HubSpot account, click the settings iconsettings in the main navigation bar.
In the left sidebar menu, click Marketing > Ads.
Click the Lead Syncing tab.
In the dialog box, select Google Ads. If you have multiple Google Ads accounts connected, select the account that you want to sync leads from, then click Save.
Follow the instructions to add the HubSpot Webhook URL and key to your Google Ads account:
Open a new browser tab and navigate to your Google Ads account.
In the left sidebar menu, click Ads & Extensions, then select Extensions.
Hover over the lead form that you want to sync leads from, then click the edit icon.
Scroll down to the Lead delivery option section.
Copy and paste the Webhook URL and Key from HubSpot into the corresponding fields of your Google lead form.
Back in HubSpot, click Done.
Users who fill out the lead form on your ad will then sync to your HubSpot account as contacts.
Please note: if you create additional lead forms in your Google Ads account, you'll need to repeat the process above to add the HubSpot Webhook URL and Key for each new lead form.
Necessary disclosure: if you configure your Google Ads account for lead syncing, HubSpot will receive webhook updates when a new lead form submission occurs in your account. HubSpot will pull all lead submissions for the connected ad account, and will log them as form submissions in the CRM.
