Understanding on Facebook Conversions API: What and Why?

The Facebook Conversions API (CAPI), formerly known as the Facebook Server-Side API, is a tool that helps businesses track customer actions and improve their Facebook advertising performance. Here’s what you need to know:

What is it?

• CAPI is a server-side solution that allows you to send conversion data directly from your server to Facebook, bypassing the browser and any privacy restrictions that might be in place.

Why is it needed?

• Changes in data privacy regulations, like Apple’s iOS 14 update, have made it more difficult to track user behavior using traditional methods.
• CAPI offers a more reliable and privacy-compliant way to track conversions, ensuring you have a clearer picture of your advertising performance.

Benefits of using the Facebook Conversion API

The FCAPI offers enhanced privacy and data control, allowing you to track and measure conversions without relying solely on browser-based tracking. Additionally, the API enables you to send customer data directly to Facebook, ensuring accurate attribution and improved ad targeting.

• Enhanced privacy and data control
• Direct customer data transmission

What will be chosen over Facebook Conversion API or Facebook Pixel?

Facebook is definitely encouraging businesses to adopt the Conversions API (CAPI) alongside or even prioritize it over the Facebook Pixel. There are strong indications pointing towards its increasing importance:

1. Privacy Regulations: As, stricter data privacy regulations like GDPR and Apple’s iOS 14 update are making browser-based tracking (relied upon by the Pixel) less reliable. CAPI, through server-to-server communication, offers a more compliant and robust solution.

2. Offline Conversion Tracking: CAPI allows tracking conversions happening outside your website (app installations, phone calls), something the Pixel can’t do effectively. This provides a more holistic view of your advertising impact.

How FCAPI works with Server-Side Google Tag Manager(GTM) Container?

Imagine a user interacting with your website:

• Action: The user clicks a button, makes a purchase, or performs another action.
• Dual response:
  • Client-side: The Google Analytics 4 (GA4) web tag in your client-side GTM container fires, capturing data like events, pageviews, and variables.
  • Server-side: A server request is made, triggering the GA4 web client in your server-side GTM container.
• Data journey:
  • Client-side data: The GA4 web tag sends its captured data to the GA4 web client within the server-side container.
  • Server-side processing: The server-side container processes the combined data, including additional parameters you might have configured.
• Third-party destinations: The server-side container then sends relevant data to individual third-party tags, like Google Analytics 4 and the FCAPI tag.
• FCAPI activation: The CAPI tag, armed with the necessary parameters, formats the data according to Facebook’s specifications and securely transmits it to Facebook’s server.

Set Up Facebook Server-Side Tracking GTM

Step 1: Select Pixel

Go to the Business Settings, in your company manager. Select your company and click on “Ads Manager”.

Step 2: Open the Event Manager

Now, click on the ‘All Tools’ option and then click on ‘Event Manager’ section.

Step 3: Navigate to the Data Source Tab

Navigate to the ‘Event Manager’. You have to generate the ‘Access Token’ for adding into the FCAPI tag. So, if you have not generated the Token, you have to follow this website. So that we can interact with the API.

Step 4: Create Tag in Server-Side Google Tag Manager (GTM) container

Now that you’ve generated your access token, navigate to the “Tags” section of your server container in Google Tag Manager. Click “New” to begin creating a new tag.

Step 5: Configured the (FCAPI) Tag

Click on “Tag Configuration”. Under the ‘Discover More Tag Types in the template gallery..’. Search for the Facebook Conversion API.

Step 6: Set the Tag and add the Appropriate Field

Now, under the Event Name Setup method: select Inherit from the client. The Access Token which you have generated paste it into the ‘API Access Token’. Next, enter your Facebook Pixel ID.

Step 7: Configure the trigger

Now that you’ve set up the FCAPI tag in Google Tag Manager, let’s configure it to trigger whenever a GA4 event occurs. This will automatically send all your GA4 events to Facebook, where they’ll be mapped to their corresponding standard Facebook events:

• view_item will become viewContent
• add_to_cart will become addToCart and so on…

Step 8: Save the Tag

Give the new tag a name, and click on “Save”.

Step 9: Preview the Tags and triggers. Checking business manager

After setting up all the things, test and preview the server-side GTM and check whether they are reflecting or not. Also, check into the Facebook Business Manager -> Data Source -> Event Manager -> Click on the pixel of which you have added the Pixel ID. You will able to see the events from the Browser and Server. 

Testing and validating event data

Before you unleash the full power of the Conversion API, it’s crucial to test and validate your event data to make sure everything is spot on. Here’s how to play data detective:

1. Check for Proper Event Setup:

• Verify parameters: Confirm that the additional details you’re sending (like purchase value or product IDs) are accurate and formatted correctly.

2. Confirm Event Matching:

• Compare events in Events Manager: Double-check that the events you’re sending align with the events Facebook is receiving. This is like making sure your dance partner is on the same beat.

By following these steps, you’ll ensure that your data is reliable and ready to fuel your advertising success. Accurate data is like a trusty map—it guides you to the right destination!
