How to Connect Facebook Leads to Klaviyo (Automated Setup)

If you are running social media ad campaigns, you already know that speed is everything. The longer a prospect waits for a follow-up, the colder they get. But if you are wondering how to connect Facebook leads to Klaviyo without manually downloading and uploading CSV files every day, you aren’t alone.

In this guide, we will show you exactly how to set up a direct Facebook to Klaviyo integration using LeadsNotify. By automating this process, your new leads from Facebook Lead Ads will instantly trigger your Klaviyo email sequences the moment they hit “submit.”

Why Automate Your Facebook to Klaviyo Pipeline?

Facebook Lead Ads are incredible for capturing high-intent prospects directly from their newsfeed. However, Facebook does not natively push these leads into Klaviyo. Without an integration tool, marketers are stuck performing manual data entry.

Setting up the LeadsNotify Klaviyo integration allows you to:

• • Eliminate manual CSV exports: Stop wasting hours moving data from your Facebook Page to your email lists.

• • Trigger instant welcome emails: Enter new Facebook leads into a Klaviyo welcome flow while your brand is still top-of-mind.

• • Improve lead conversion rates: Industry data shows that responding to a lead within the first 5 minutes drastically increases conversion chances.

Prerequisites: What You Need to Get Started

• • Admin access to your Facebook Business Page.

• • An active Klaviyo account.

• • A specific Klaviyo List created where you want these new Facebook prospects to populate.

• • A free or premium LeadsNotify account.

How to Connect Facebook Leads to Klaviyo (Step-by-Step Guide)

Follow these straightforward steps to connect your Facebook Lead Forms directly to your Klaviyo marketing lists.

Step 1: Connect your Facebook Account to LeadsNotify

Log in to LeadsNotify. Open the Connectors section in the dashboard, find Facebook, and follow the simple authorization steps. If you need help, refer to our Facebook connection setup guide. Once connected, LeadsNotify will be able to read the Instant Forms associated with your Facebook Page.

Step 2: Create a New Klaviyo Notifier

Click on Create Notifier in the header menu, search for “Klaviyo“, and click on Try Now.

In the configuration section, select your Facebook Page and the specific instant form you are running ads to. LeadsNotify will instantly display the data fields (First Name, Email, Phone, etc.) that your Facebook form collects.

Step 3: Generate a Klaviyo Private API Key

To securely send Facebook leads to Klaviyo, you need to provide LeadsNotify with a Private API Key.

1. 1. Log in to your Klaviyo dashboard.

1. 1. Click your organization name in the bottom left corner and go to Settings.

1. 1. Navigate to API Keys.

1. 1. Click Create Private API Key. Name it “LeadsNotify Facebook Integration” so you remember what it is for. Ensure this key has Full Access to “List” and “Profiles.”

1. 1. Copy the generated API key.

Step 4: Map Your Facebook Fields to Klaviyo

Return to the LeadsNotify setup screen. Paste your copied Klaviyo API key into the API Key input field and click Submit.

LeadsNotify will securely authenticate the connection and retrieve your available Klaviyo Lists. Select the exact List where you want these leads to go. Next, map your fields (for example, connect the Facebook “Email Address” field to the Klaviyo “Email Address” property). Scroll down and click Submit to save the notifier.

How to Test Your Facebook to Klaviyo Integration

Before spending your ad budget, you must test the workflow to ensure data is passing smoothly. LeadsNotify makes this incredibly easy with a built-in testing feature.

1. 1. Use the Automated Test Prompt: Once you’ve mapped your fields and clicked “Submit” to save the integration, LeadsNotify will automatically display a popup prompting you to send a test lead.

1. 1. Send the Test Lead: In the popup, simply select your connected form and click “Send Now.” LeadsNotify will immediately push sample data through the integration.

1. 1. Check Klaviyo: Log in to Klaviyo and open the List you selected during setup to verify the test contact was added.

Important Note on Klaviyo Double Opt-In

If your test lead does not appear immediately, check your Klaviyo List settings. If Double Opt-In is enabled, Klaviyo will send an automated confirmation email to the test address. The profile will not appear on your active list until you log into that test inbox and click the confirmation link. If you prefer leads to sync instantly, you can disable double opt-in for that specific list inside Klaviyo’s settings.
