How to map Facebook and LinkedIn lead ads fields to Hubspot properties

When you sync Facebook and LinkedIn lead generation campaigns with Hubspot, the way each ad platform’s form fields map to contact properties determines how usable your data will be. Understanding these default mappings and how to manage them helps you keep your CRM organized and your lead records accurate.

This guide walks through how lead ad fields map into the CRM, which properties are created by default, and what you can customize when working with connected ad accounts.

How Hubspot connects to lead ad forms

Hubspot uses native integrations with Facebook and LinkedIn to capture submissions from your lead generation forms and automatically create or update contacts.

When a form is submitted:

• The ad network sends the field values to Hubspot.
• Hubspot matches each field to a contact property according to a predefined mapping.
• Contacts are created or updated, and associated with the relevant ad campaign.

The integration relies on supported field types and names, so it is important to understand which ad form fields are compatible.

Supported Facebook lead ad fields for Hubspot

Facebook lead generation forms offer many standard fields, but only a subset is supported for direct syncing into the CRM.

Standard Facebook fields mapped to Hubspot properties

When you use Facebook’s predefined fields, Hubspot maps them to specific contact properties such as:

• First name
• Last name
• Email
• Phone number
• Job title
• City, state, and country
• Company name

These fields are configured so that values from the form are written into the matching CRM properties without extra setup.

Unsupported or custom Facebook fields

Some Facebook fields cannot be synced automatically:

• Certain demographic or ad-specific fields
• Custom questions that do not match existing properties

For those questions, Hubspot stores the raw submission data differently or may not map it directly to standard contact properties. If you need to use this information in your CRM, you may have to create custom properties and align them with your form questions where possible.

Supported LinkedIn lead gen fields for Hubspot

LinkedIn lead gen forms also include a wide variety of default fields. Hubspot supports many of these and maps them to appropriate CRM properties.

Standard LinkedIn fields mapped to Hubspot

Common LinkedIn fields that map into contact records include:

• First name and last name
• Email address
• Phone number
• Company name and company size
• Job title, job function, and seniority
• Country and location details

These fields align closely with CRM properties so your sales and marketing teams can segment and report on LinkedIn-sourced leads effectively.

Custom LinkedIn questions

LinkedIn allows custom questions in lead gen forms. However, custom questions do not always match existing CRM properties. In those cases, Hubspot captures the responses as part of the submission payload but may not map them to default fields. Consider creating custom properties in your CRM to store these responses if you plan to use them for segmentation or workflows.

Default lead ad properties created in Hubspot

When you first connect an ad account and start syncing leads, Hubspot may create certain default properties to store lead ad details. These can include:

• Identifiers for the ad network and campaign
• The lead form used
• Timestamps or ad-specific metadata

These properties allow you to filter contacts by ad source, campaign, or form. They are especially useful when analyzing performance of your paid channels.

How to review field mappings in Hubspot

You can verify how your lead ad fields map with a simple review process.

Steps to check mappings for Facebook and LinkedIn

1. Open your CRM account and go to your ads settings.
2. Select the connected Facebook or LinkedIn account.
3. Locate the lead syncing or lead mapping section.
4. Review which form fields are currently supported and see how they map to properties.

This overview helps you confirm that critical data, such as email and phone number, will always populate correctly in contact records.

Best practices for lead ad form design in Hubspot-connected accounts

To make the most of your integration, design lead ad forms with mapping behavior in mind.

Use standard fields where possible

Whenever available on Facebook or LinkedIn:

• Choose email, name, and phone fields from the platform’s built-in options.
• Use standard company and job-related fields for B2B campaigns.
• Avoid replacing key identity fields with custom questions.

Standard fields have predefined mappings, improving reliability and reducing the risk of incomplete contact records in Hubspot.

Limit and plan custom questions

When you need custom questions:

• Decide exactly how you will use each answer in the CRM.
• Create custom properties in the CRM that align with the question.
• Confirm whether the integration can associate those answers with your custom properties.

This planning step ensures your lead forms remain concise while still capturing strategic information.

Troubleshooting lead ad field mapping in Hubspot

If lead information from Facebook or LinkedIn is not appearing as expected, examine the following areas.

Confirm the ad account and form connection

First, make sure:

• The ad account is fully connected in your CRM settings.
• The specific lead form is selected or allowed for syncing.
• Permissions have not changed in Facebook or LinkedIn.

Disconnected or partially authorized accounts can prevent proper field mapping.

Check for unsupported fields

Next, compare your form fields with the list of supported fields on the official documentation. If you are relying heavily on custom questions or unsupported fields, those answers may not appear in standard contact properties.

Using mapped lead data in your CRM

Once your mappings are working correctly, you can use the synced data to drive revenue operations.

Common ways to leverage mapped data

• Build contact lists based on lead ad campaign or form.
• Trigger follow-up workflows for new ad-sourced contacts.
• Report on performance by ad network, campaign, or audience.
• Score leads based on role, company size, or location.

Because mapped fields feed into standard CRM properties, they integrate seamlessly with existing lists, reports, and automations.
