How to Track Phone & Email Leads in LinkedIn Using Zapier's Conversions API
TABLE OF CONTENTS
Most LinkedIn conversion tracking guides focus on form submissions, but what about those valuable leads who pick up the phone or send a direct email? These offline conversions often represent your highest-intent prospects, yet they frequently slip through the cracks of digital attribution.
"The vast majority of our quality leads come from people calling on the phone or people emailing the alias address on the website," explains Stephania P., a B2B digital marketing agency owner. "If we're only going off contact forms, it's an incomplete story."
The solution? Use your CRM's deal creation process as the trigger for LinkedIn conversion tracking. Instead of relying on website actions, this approach lets you capture conversions when your team creates deals from phone calls and direct emails.
"What we do is customize the workflow to say, okay, if we have a new contact, and the contact has specific attributes like a phone number, send it to LinkedIn's API," explains Jeremiah, a Zapier integration specialist.
The implementation requires three key components:
- A CRM field to mark the lead source (phone, email, form)
- A Zapier workflow triggered by new deal creation
- A filter to ensure only inbound leads are tracked
"Anytime someone fills a form on your website, it creates a contact. If someone clicks on email or calls, then you manually add that in - but it's still being tracked because everything goes into the CRM," Jeremiah notes.
This approach ensures your LinkedIn campaign metrics reflect the full impact of your advertising, including those high-value offline conversions that traditional tracking might miss.
