Using Meta Pixel and Conversions API (CAPI) together is the best way to improve your ad tracking and performance on Meta platforms. Here's why:
Meta Pixel: Tracks user actions on your website (like clicks, purchases, and page views) using browser data. However, privacy measures like iOS restrictions and ad blockers can limit its effectiveness.
Conversions API (CAPI): Sends data directly from your server to Meta, bypassing browser issues. This ensures you capture more conversion data, even in cases where Pixel falls short.
Why use both?
Meta Pixel captures browser-side data, while CAPI collects server-side information. Together, they provide a complete view of user behavior, improve data accuracy, and help Meta's algorithms optimize your campaigns. Using both can recover up to 90% of lost conversion data and reduce ad costs.
Key benefits:
Fewer data gaps caused by privacy restrictions.
Accurate conversion tracking through deduplication of events.
Better targeting and audience building with enriched data.
For seamless integration, tools like AdAmigo.ai can simplify setup and automate campaign optimization, saving time and effort while improving results.

How Meta Pixel and CAPI Work Together
Using Meta Pixel and CAPI together creates a well-rounded tracking system: Pixel handles browser-side actions, while CAPI manages server-side data. This combination helps address each other's weaknesses. Here's a closer look at how they handle event deduplication and data consistency.
Addressing Browser Tracking Challenges
Browser tracking has become less reliable due to privacy measures like Apple's Intelligent Tracking Prevention (ITP) in Safari and the App Tracking Transparency (ATT) framework in iOS 14+. Additionally, ad blockers like Brave and DuckDuckGo can block Pixel scripts, leading to data losses of up to 20–40% [4].
CAPI solves this issue by using server-to-server communication, which bypasses ad blockers and captures events even if a user closes the page early. This approach improves the accuracy of ROAS metrics and ensures better attribution when client-side tracking fails. Charles Farina, Head of Innovation at Adswerve, explains:
"The future of measurement is not about finding a 1:1 replacement for the cookie, but rather building a new foundation that is durable and privacy-safe. Server-side tagging and APIs like the Conversions API are not just workarounds; they are central components of that new foundation. Businesses that master this will have a significant competitive advantage." [4]
Managing Event Deduplication and Synchronization
When both Pixel and CAPI report the same event - like a purchase - Meta uses deduplication to prevent counting the event twice. This process matches event names and unique event_id values to ensure accurate conversion data.
To make this work, assign a unique event_id to each conversion. For example, if the Pixel sends a "Purchase" event with eventID: '12345', your server should also send the corresponding CAPI event with event_id: '12345'. Meta compares these events over a 48-hour window. If the event names and IDs match, one instance is kept, and the duplicate is discarded [1][5]. A healthy deduplication rate ranges between 40–60%, which you can monitor in Facebook Events Manager [4].
Once deduplication is in place, it's vital to ensure that data from both sources is perfectly aligned.
Ensuring Consistency in Conversion Data
For deduplication to work, Pixel and CAPI must use identical, case-sensitive event names. For instance, a "Purchase" event from the Pixel won't match with a "purchase" event from CAPI.
Additionally, enrich each event with as much hashed customer data as possible - such as email, phone number, name, city, state, ZIP code, and Facebook identifiers like fbc (click ID) and fbp (browser ID) [4]. This extra information enhances your Event Match Quality score, which is critical for accurate conversion attribution. Aim for a score of 8 out of 10 or higher. With more data points, Meta's algorithms can better target high-intent users, optimize bids, and reduce acquisition costs, making your ad spend more effective.
Setting Up Meta Pixel and CAPI Integration
Prerequisites: Meta Business Manager and Pixel Creation
To get started, register as a Facebook Developer to access the necessary tools. In Meta Business Manager, either create a new Pixel or locate an existing one, ensuring you have access to the Pixel ID for integration. It's important to have developer privileges within your Business Manager account; without these, the required options for setup won’t appear.
Generating CAPI Access Token
Once your Pixel is ready, the next step is to authenticate your API calls. Navigate to the Settings tab in Events Manager and locate the "Conversions API" section. Click on "Generate access token" and follow the prompts to complete the process [5]. This token is crucial - it authenticates every server-side event sent to Meta by being included as a parameter [6].
After generating the token, go to the Overview section in Events Manager. Click "Manage Integrations" and then "Manage" next to "Conversions API." This step automatically creates a Conversions API app and system user, simplifying permissions and bypassing the need for App Review [5]. When sending events via POST requests, include the token as a query parameter in your call structure:
https://graph.facebook.com/{API_VERSION}/{PIXEL_ID}/events?access_token={TOKEN} [6]. After integration, verify that your events are being tracked accurately.
Testing and Troubleshooting the Integration
To ensure your setup is working, use the Test Events tab in Events Manager. Launch the ssGTM preview mode and leverage Facebook's Test Events tool to confirm that server-side and browser-side event tracking are functioning simultaneously [5].
Pay close attention to event name matching. Server-side and browser-side events must have identical names, as this is case-sensitive. Double-check that events are being received in near real-time, deduplicated correctly, and matched precisely [5]. Consistency is key - include the Event ID across all Facebook tags to maintain alignment [5]. If updates don’t appear immediately, refresh your browser and try again. Continuously monitor the flow of event data from both CAPI and the browser Pixel in Events Manager to identify and address any issues early [7][3].
Scandiweb highlighted this setup process in October 2022, stressing the importance of developer privileges within Meta Business Manager for effective tracking [5].

Meta Pixel vs Conversions API: Complete Comparison Chart
Better Data Accuracy and Attribution
When Meta Pixel and Conversions API (CAPI) work together, they create a more complete picture of your customer’s journey. While Meta Pixel alone can lose 20–40% of conversion data due to factors like iOS 14's App Tracking Transparency, Safari's Intelligent Tracking Prevention, and ad blockers, CAPI steps in to fill those gaps. It does so by directly sending key events - like purchases or sign-ups - straight from your server. By using matching identifiers such as event_id and event_name, it avoids duplication, ensuring your conversion metrics are spot-on [1][4][5].
This dual tracking system doesn’t just fix data gaps - it also enriches the data you collect. CAPI allows you to send more detailed customer information, like hashed emails, phone numbers, names, locations, Facebook Click IDs (fbc), and Browser IDs (fbp), directly from your server. This richer data improves Meta's Event Match Quality, making it easier to connect ad clicks to real-world purchases [5].
In short, better data accuracy lays the groundwork for more effective ad performance.
Improved Ad Optimization
With a unified and accurate data set, ad performance gets a serious boost. Marketers using a well-configured Conversions API setup have reported impressive results, including a 33% increase in incremental purchase events and an 82% increase in incremental subscription events [7]. With more complete and reliable signals, Meta's algorithms can better target users who are most likely to convert.
Beyond improving performance metrics, this integration also enhances custom and lookalike audiences. By gaining a fuller understanding of user behavior, you can build audiences based on real actions rather than incomplete browser data [5].
