Integrate Facebook CAPI to optimize advertising
Facebook (now Meta) has dominated the digital advertising industry for over a decade thanks to the vast amount of user data. However, with changes in privacy policies and the rise of ad-blocking tools, Meta developed Facebook Conversion API (CAPI) as an alternative to Facebook Pixel. Let's explore in detail what CAPI is and the key events you need to know when using CAPI in your advertising campaigns.
1. What is Facebook CAPI?
Facebook CAPI is an API provided by Meta that allows you to send conversion data (such as completing a purchase or adding a product to the cart) directly from your server to Facebook's server. This method eliminates the dependency on browser tracking, allowing you to send more accurate and efficient signals to Facebook, helping to build audiences and optimize advertising campaigns.
CAPI is not only an alternative to Pixel but also brings several superior benefits such as:
Increased Accuracy: Sending data server-to-server helps avoid disruptions caused by ad-blocking tools or browser privacy policies.
Better Data Management: CAPI allows you to use your first-party data to improve targeting and help Facebook optimize ad algorithms based on actual customer behavior.
2. Comparing Meta Pixel and Facebook CAPI
| Criteria | Meta Pixel | Facebook CAPI |
|---|---|---|
| Data Collection Method | JavaScript (Embedded code on the website) | Server-to-server API |
| Reliability | Dependent on cookies and browsers, easily disrupted | Highly reliable, unaffected by cookies or ad-blockers |
| Data Type | Only sends data from browser events | Can send all types of event data, including offline data |
| Setup Process | Easy, requires JavaScript code installation | Requires technical setup and API integration |
| Security and Compliance | Dependent on cookies and local storage in the browser | Data is sent in a secure server environment, compliant with security regulations |
3. Facebook CAPI vs. Facebook Pixel
Data is a crucial element across all advertising platforms, especially on Facebook. The more data Facebook has, the better its algorithms can optimize ad campaigns, allowing you to confidently spend money, reduce costs per action, and achieve better ROAS (Return on Ad Spend).
Facebook already has a large amount of data from Meta user profiles, including demographic information, interests, pages users interact with, and many other actions, which help create highly targeted audiences for your ad campaigns.
However, another key factor that helps train Facebook’s ad algorithm is conversion events. These events reflect customer actions, such as page views or purchases, and help Facebook optimize ad campaigns. Without setting up conversion events through CAPI, these server-side events won't be recognized by Facebook and will not contribute to improving the algorithm.
Facebook Pixel – The Previous Approach
Before CAPI was introduced, Facebook Pixel was the primary tool for sending conversion events from websites to Facebook. Pixel works by embedding JavaScript code on your website, placing cookies on the user's browser, and tracking actions such as clicks, page views, or purchases. A major advantage of Pixel is that it is easy to set up and use.
However, Pixel has some limitations:
Less Flexibility: Pixel can only collect data from user interactions on the website, limiting the ability to track data from other sources or offline actions.
Privacy Issues: Growing privacy concerns have led users to often opt-out of data collection. This has resulted in browsers like Chrome starting to discontinue the use of third-party cookies, and laws like GDPR, CCPA, and CPRA require companies to protect users' personal data more strictly. Additionally, ad-blockers are becoming more common, causing disruptions and inaccuracies in Pixel data.
Facebook CAPI – The New Solution
Facebook CAPI is a solution developed by Facebook to overcome the limitations of Pixel. CAPI allows you to send conversion events directly from your server to Facebook’s server, without worrying about privacy issues or being blocked by browsers or ad-blockers.
Some of the advantages of CAPI over Pixel include:
Higher Flexibility: CAPI allows you to send multiple types of conversion events and additional data from your server, something Pixel cannot do.
Better Data Control: You have full control over the data you send via CAPI, including determining user IDs and conversion events. This helps you avoid user consent issues and ensures compliance with security regulations.
No Disruptions: CAPI operates via servers, meaning it is not affected by ad-blockers or issues related to third-party cookies.
Increased Accuracy: By sending server-side data, you can leverage your first-party data to optimize ad campaigns and improve the accuracy of ad algorithms.
Although setting up CAPI can be more complex than Pixel, it offers greater long-term benefits, especially in overcoming privacy issues and accurately tracking conversion events.
Benefits of using Facebook CAPI:
Improved Data Accuracy.
Ability to track a wide range of events.
Compliance with security regulations such as GDPR, CCPA.
Reduced impact from ad-blockers and third-party cookies.
Combining Facebook CAPI and Pixel will help you build a comprehensive advertising strategy, optimize your data, and achieve better campaign results.
4. What is a Dataset?
A Dataset in Facebook CAPI is a collection of data used for analyzing, optimizing ads, and customizing advertising campaigns on the Facebook platform. It is where you can connect and manage event data from various sources, making data tracking and analysis more accurate and effective.
What Does a Dataset Do?
A dataset helps you connect events from multiple platforms, including websites, mobile apps, offline sales data, messaging data from third-party tools like AhaChat, etc. In this way, you can aggregate all user events into one central place, optimizing your advertising campaign.
How Does the Dataset Work with CAPI?
For example: You have a dataset X linked to Facebook page A, Instagram page B, and WhatsApp page C. When you use Facebook CAPI to connect, all events from these three platforms will be recorded in dataset X.
How Are Datasets and CAPI Related?
In simple terms, Dataset is the place where event data is stored, while CAPI is the method to transmit data into this dataset from various sources. This helps you manage event data efficiently and consistently, optimizing the advertising and measurement process.
For more details on how to use Datasets in Facebook CAPI, you can refer to Facebook's Guide.
5. How to Set Up Facebook CAPI?
There are two main methods to set up Facebook CAPI: through partner platform integration or manual setup.
Partner Platform Integration: You can set up Facebook CAPI without code using partners who have integrated with Facebook. Just follow their setup instructions.
Manual Setup: If you want more control over the events you send and have technical knowledge, you can set up Facebook CAPI directly.
To integrate Facebook CAPI into AhaChat, you can refer to the detailed guide at AhaChat's Facebook CAPI Setup Guide.
6. Key Events in Facebook CAPI
Facebook CAPI not only helps send conversion signals from servers but also supports tracking many important events, making it easier to optimize your ad campaigns. Below are three fundamental and crucial events you need to know when integrating CAPI into your ad campaigns:
1. Facebook CAPI Purchase
The Purchase event is triggered when a user completes a purchase transaction on your website. Tracking this event helps you measure the effectiveness of ads related to purchases and track ROAS (Return on Ad Spend). This is crucial for assessing the effectiveness of your ad campaigns.
Corresponding Ad Type on Meta:
Campaign Objective: "Engagement", with the Optimization Goal set to “Maximize purchases via messaging”.
With this setup, Meta will deliver your ad to users who are most likely to make a purchase through a conversation on Messenger.

2. Facebook CAPI Lead
The Lead event is triggered when a user fills out a registration form or provides contact information on your website, such as signing up for a newsletter or downloading a document. This event is important for B2B marketing campaigns or campaigns that require lead generation.
Corresponding Ad Type on Meta:
Campaign Objective: "Lead Generation" → Conversion Location: “Messenger”.
Optimization Goal: “Maximize Leads”.
This setup allows you to collect user information directly within the conversation, while also improving lead quality through behavior-based optimization.
