Automate Facebook Ads with Zapier

Using Zapier, you can connect tools like Synthesia and Meta’s Conversions API to automate Facebook ad workflows, improve tracking, and optimize performance without writing code.

This how-to guide walks you through building an automation stack that transforms raw website data into targeted video ads, then sends accurate conversion events back to Facebook for better optimization.

Why connect Synthesia and Facebook with Zapier?

The source tutorial from Zapier’s blog on Synthesia and Facebook Conversions API shows how powerful this setup can be for marketers who rely on Facebook ads.

By inserting Zapier between your marketing tools, you can:

• Automatically generate personalized video ads based on website behavior.
• Send conversion events directly to Facebook through the Conversions API.
• Reduce data loss from ad blockers and browser restrictions.
• Improve optimization signals for campaigns and ad sets.
• Scale your marketing without manual exports and uploads.

What you need before building your Zapier workflow

Before setting up automation, confirm you have the following pieces in place so Zapier can connect them.

Core accounts required for Zapier automation

• A Zapier account with access to multi-step Zaps.
• A Synthesia account with video templates you want to customize.
• A Meta Business Manager account with a Facebook pixel and Conversions API access.
• Admin access to the Facebook ad account you plan to use.
• A website or app where events such as leads, sign-ups, or purchases occur.

Data and infrastructure checklist

For Zapier to route events correctly, you also need:

• Standard events defined (e.g., Lead, Purchase, CompleteRegistration).
• Key user identifiers (like email, phone, or external IDs) you can capture.
• Basic naming structure for campaigns and ad sets.
• At least one Synthesia video template to personalize.

Step 1: Plan your Zapier-powered funnel

Before you open Zapier, design how data will flow across tools. Start with three core questions:

1. What triggers the workflow?
   Examples: form submission, new lead in your CRM, new row in a spreadsheet, or a conversion event from your site.
2. What should happen in Synthesia?
   Examples: personalize a video with the lead’s first name, industry, or product of interest.
3. What events should go to Facebook?
   Examples: page views, leads, add-to-cart events, or purchases sent through the Conversions API.

Sketch this funnel so you know exactly which steps Zapier needs to orchestrate.

Step 2: Create the trigger Zap in Zapier

Your first automation will start when a new user or event appears in a data source. In Zapier, this is your Zap trigger.

Configuring the trigger in Zapier

1. Log in to Zapier and click Create Zap.
2. Choose your trigger app (for example, your form tool or CRM).
3. Select the trigger event, such as New Form Submission or New Lead.
4. Connect your account and authorize Zapier.
5. Test the trigger to pull in a recent example lead or event.

Make sure the sample data includes key fields like name, email, and any attributes you want to use inside Synthesia or send to Facebook.

Step 3: Send data to Synthesia through Zapier

Next, add actions in Zapier that call Synthesia’s API to generate or update a personalized video ad.

Map fields from Zapier to Synthesia

1. In your Zap, click + Add action and search for a Webhooks by Zapier step if Synthesia is not a direct app.
2. Choose POST as the webhook method.
3. Paste the Synthesia API endpoint for video creation or template rendering.
4. In the body or JSON payload, map fields from your trigger (for example, first name, product, language) to placeholders in your Synthesia template.
5. Send a test request from Zapier to confirm Synthesia creates the video.

Once this works, your automation can generate personalized creative every time a new qualified user enters your funnel.

Step 4: Capture conversions and send them with Zapier

Now you need a second automation layer where Zapier sends reliable conversion signals to Facebook through the Conversions API.

Set up conversion events for Zapier

1. Identify where conversions happen: checkout page, thank-you page, or in-app event.
2. Choose the app that will send the conversion data to Zapier, such as your payment processor, CRM, or analytics tool.
3. In Zapier, create another Zap with that tool as the trigger.
4. Pull in sample conversion data that contains value, currency, and user identifiers (email, phone, or external ID).

Post events to Facebook using Zapier

1. Add a Webhooks by Zapier action to your conversion Zap.
2. Use the Meta Conversions API endpoint URL for your pixel.
3. Map event_name (Lead, Purchase, etc.), event_time, event_source_url, value, and currency.
4. Hash user identifiers as required by Facebook or use fields that Zapier can send pre-hashed if already managed upstream.
5. Test the Zap and confirm the event appears in Events Manager with the correct pixel.

Once active, this integration sends server-side events that complement pixel data and improve optimization stability.

Step 5: Use Zapier data to optimize Facebook campaigns

With both creative and conversions passing through Zapier, you can fine-tune how your Facebook campaigns behave.

Align Zapier events with campaign objectives

• Choose campaign objectives that match the events you send via the Conversions API.
• Optimize ad sets for the same standardized events you fire with Zapier.
• Use parameters in Zapier to pass custom data such as plan type, region, or product line.

Automate feedback loops with Zapier

To go further, you can create additional Zaps to:

• Write high-value conversions to a spreadsheet for analysis.
• Notify your sales team in Slack when a key event fires.
• Tag contacts in your CRM based on which Synthesia video they received.
• Trigger retargeting sequences when users reach specific milestones.

Step 6: Monitor, test, and refine your Zapier workflows

After launching, continuously monitor how your Zapier automations perform.

Checklist for maintaining Zapier integrations

• Review Zap run history for errors and fix failed tasks quickly.
• Validate that Synthesia videos are created with the correct variables.
• Check Events Manager for signal quality and match rate from Zapier events.
• A/B test different template variations and audiences.
• Document your Zaps so your team can manage updates safely.

Where to learn more about Zapier automation
