What is Facebook Conversions API & Why Do You Need It?

November 3, 2023 By Javier Rodriguez

What is Facebook Conversions API?

API stands for application programming interface. With that in mind, the Facebook Conversions API (CAPI) is a type of software that tracks consumer actions that occur off the web. It’s a critical tool for advertisers on the platform.

However, you might be unfamiliar with this solution and how to use it.

Meta has chosen a few select agencies to partner with to provide the simplest way to use CAPI, and Ignite Visibility is one of them.

In other words, we’re ready to help you set up the Conversions API to establish a direct connection between the marketing data you collect and Meta. 

The goal of using Facebook CAPI is to help advertisers make use of first-party data, overcoming the challenges of doing so in recent years. In turn, you can optimize ad targeting, reduce cost per action, and put together a much fuller picture of your results without violating users’ privacy.

While privacy is an understandable priority for Apple, Google, and many other digital companies, it has severely limited the use of third-party data for advertisers. 

CAPI will help circumnavigate privacy measures like iOS updates using first-party data while still respecting users’ privacy.

Facebook Converions API vs. Facebook Pixel Alone

Before CAPI came along, advertisers could rely solely on Facebook Pixel to collect data from users and track campaign performance.

However, with the iOS14 update from Apple boosting privacy for users, advertisers suddenly needed more than Pixel to help with campaigns.

Enter Facebook conversion API, which can work with Facebook Pixel—now called Meta Pixel—to help you get the most from your data. While Pixel helps track the customer journey and interactions, the Conversions API will show you the end results of your efforts. 

The Conversions API ultimately helps by measuring customer actions gained from Pixel, which increases the transparency of the buyer’s journey. You can also use CAPI to decide which data to share with Facebook Ads Manager and when you want to share it.

Ultimately, using Facebook CAPI and Pixel together will help you fully understand and optimize your campaign performance.

In fact, according to one Meta study, you can reduce your cost per result by as much as 13% when combining it with the pixel. Advertisers mixing Facebook Conversion API with Pixel also see an average of 19% more attributed purchase events.

Key Benefits: Why Use CAPI?

Facebook conversion API offers multiple advantages that make it worth implementing for your ad campaigns.

Here are some of the more specific benefits of using Facebook CAPI:

Harness the Power of First-Party Data

With the release of iOS14 and other privacy measures, Apple and other companies have worked to phase out third-party data and boost user privacy. In fact, Google officially plans to get rid of third-party cookies altogether by Q1 of 2024. 

What CAPI does is help you connect customer interactions to Facebook Ads Manager more directly, helping you use valuable user data that can help you optimize your ad campaigns.

When people interact with you via your website or another interaction, such as a lead ad or CRM, you can use this data to your benefit.

Protects Users’ Privacy

Facebook CAPI allows you to collect vital user data to help you improve your ad targeting and personalization capabilities. 

At the same time, you’ll maintain users’ privacy. 

Instead of relying on third-party data, you’ll collect first-party data through direct interactions, eliminating the need for Facebook Pixel alone.

Boosts Overall Ad Performance

Deeper insights into customer actions and the customer journey will help you fully optimize your ads. 

By integrating Facebook Conversion API, you can enhance Meta Pixel and gain full transparency into how people are interacting with your brand.

If you want to future-proof your marketing strategy, CAPI integration will go a long way in doing so.

Why Marketers Should Really Care

Marketers want to make full use of CAPI to ensure their campaigns can succeed with the lowest cost per acquisition (CPA) and other expenses.

Facebook Conversions API allows for this by giving marketers more control over data sharing and collection. These capabilities enable marketers to paint a complete picture of the customer journey. 

Also, marketers can target the right people by giving Meta all the correct signals it needs for running ad campaigns. As a result, you can avoid any false positives or negatives that might otherwise hurt your efforts.

Perhaps most importantly, marketers will need CAPI once third-party cookies are officially gone. Using the Conversions API, you can use first-party data to effectively compensate for the loss of third-party data.

How to Set Up Facebook Conversions API

To set up CAPI for data sharing, take the following basic steps:

Step 1: Set Up Your Meta Business Suite Account

The first thing you’ll need to do is set up a Meta Business Suite account. Setting up a Business account will allow access to both Facebook Pixel and Ads Manager. Together, both of these tools will help you measure and track customer actions.

Step 2: Create a Meta Pixel

After setting up your Meta Business Suite account, the next step is to create a Meta Pixel. A pixel places a line of code on your website that allows you to share interaction data with Facebook Ads Manager.

Step 3: Install a Meta Pixel on Shopify and/or WooCommerce

If you have a Shopify or WooCommerce store, or both, you’ll want to install the pixel on these platforms.

To install the Meta Pixel on Shopify, all you need to do is go to your dashboard and into the Online Store section. From there, click on Preferences and add the pixel to your Shopify site.

To set up the pixel on WooCommerce, you’ll need to go through the following process:

  1. Look for and install the WordPress “Facebook for WooCommerce” plugin, and be sure to activate it once installed.
  2. Through the plugin settings, you can connect the plugin to your Facebook Business account, which will connect it to your Meta Pixel and other features.
  3. Choose the settings through the plugin that match your preferences, and include the pixel ID you created in the plugin’s “Facebook Pixel ID” box.
  4. Access the “Conversion API” section of the plugin settings, enabling it and allowing you to make any additional changes to settings.

Step 4: Test the Pixel

With the Meta Pixel installed on your Shopify or WooCommerce store, you can make sure it’s working right. The Meta Pixel Helper tool will allow you to test your unique pixel.

Step 5: Set Up Facebook Conversion API

You can now set up your Facebook Conversions API. This process involves accessing your Facebook Business account and going into the Ads Manager section. Here, you can click on Conversions API, where you can select the right configuration for your site.

Step 6: Set Up Events in CAPI

One last step involves setting up events through the Conversions API, which you can do in the following steps:

  1. Create a specific event to track within the Conversions API, which could be a signup, purchase, and app installs, among others.
  2. Use your Meta Pixel ID when setting up the event.
  3. Use Facebook Events Manager to finish setting up the event. Choose the appropriate pixel and include the specific details about your event.
  4. Add the event code to a designated website or mobile app. When someone completes the event, the data will go from that site or app straight to Ads Manager.
  5. Test the event for yourself by completing the event and determining if any data goes to Facebook Ads Manager.
  6. Begin tracking your event to measure the data and determine what steps to take to optimize performance.

Successful Examples of CAPI

Facebook Conversions API FAQs

Have additional questions extending beyond “What is the Conversions API?” Here are some frequently asked questions and corresponding answers to help out.

1. Why should I use the Conversions API and Meta pixel together?

Using the Facebook Conversion API with Meta Pixel, you can get even better results from your ad targeting. You’ll also be able to more effectively measure and optimize your campaigns.

Even if you already have a Meta Pixel set up, you can seamlessly integrate the Conversions API.

2. Does the Conversions API negatively affect tracking or websites?

No, integrating Facebook CAPI with your website or app won’t have any negative effect on your data or setup. The only way it could hurt your campaigns is if you remove your Meta Pixel.

3. What types of events can you track with the Conversions API?

There are three main types of events you can measure and track with your Conversions API setup: Website events, app events, and offline conversions. 

For instance, when people download your app or sign up on your website, this data will go directly to your Facebook Ads Manager for tracking. These events would be the same as the ones you already track through a Meta Pixel.

4. How can I optimize my CAPI setup?

There are multiple ways you can improve your Conversions API setup, including:

  • Sharing as many relevant parameters as possible to optimize event match quality
  • Sharing the same events with a website-plus-server connection
  • Avoiding duplicate events
  • Sharing events in real-time or near-real-time

5. What are the best parameters to share with the Facebook Conversion API?

You’ll be able to match events with accounts more effectively if you share more events with more customer information parameters. 

Parameters to share could include client IP addresses along with hashed emails or phone numbers. It really comes down to the specific audiences you want to track when prioritizing parameters.

6. What is event match quality?

One key metric to consider is event match quality, which gauges how well the parameters you share for each event can match the event with accounts. 

The higher the event match quality, the more you’ll be able to reach the right people at the right time with your ads. You’ll also improve attribution for your events to determine which ads are getting the best results.
