Meta (Facebook) CAPI Setup

How to Find Your Meta Pixel ID

Open Meta Events Manager and select the Pixel you want to use from the data sources in the left menu. Your Pixel ID appears in the upper-right corner of the detail screen.

Creating a Tracker

A tracker connects one or more sources (your website) to one or more destinations (ad platforms like Meta). Signals flow from source to every connected destination, giving you a single place to manage, monitor, and optimize your event pipelines.

Multiple trackers let you run separate configurations per domain, campaign, or destination — so each setup gets the tracking strategy it needs without cross-contamination.

If this is your first tracker, SignalSight opens the setup wizard and walks you through creating a source and destination.

Select the domain where you'll implement Conversions API. To use your own subdomain, enter the subdomain hostname in the source configuration.

Under Destinations, enter your Meta Pixel ID and Access Token, then save.

Enable Pixel Tracking at the browser level too to create both a Meta Pixel destination and a CAPI destination — so you receive events from the browser and the server simultaneously.

Once both Meta Pixel and Meta CAPI destinations are created, you can proceed to the next step.

Why Create a Subdomain?

A custom subdomain makes your tracking code first-party on your website. That improves data resilience — more signals get through browsers and ad blockers — and delivers better integration performance than a shared generic domain.

How to Create a Subdomain

Steps vary by registrar or hosting provider, but the process is the same everywhere:

1. 1Log in to your domain registrar or hosting account — where you purchased your domain.
2. 2Open DNS Management or Domain Management.
3. 3Find the option to create a new subdomain — usually under Subdomains or DNS Records.
4. 4Enter your subdomain name. For example, track.example.com for the domain example.com.
5. 5Choose an A Record to map the subdomain to an IP address.
6. 6Enter the target IP — your web server, load balancer, or the address SignalSight provides.
7. 7Save and wait for DNS propagation (a few minutes to a few hours depending on your provider).

Apply Your Subdomain in SignalSight

After your subdomain is live, enter it in the source hostname field when creating or editing a tracker.

Generate a Meta Access Token

Create access tokens under the Settings tab of the Pixel you want to connect via CAPI in Meta Business Manager.

1. 1Open your business Pixel in Events Manager.
2. 2Assign the Pixel to a system user — or create a new system user at this step.
3. 3Scroll to the Conversions API section and click Generate access token.

Name your tracker, review the source and destination configuration, and complete the wizard.

Your tracker is ready. Click Continue to open the tracker detail screen for further adjustments.

On the tracker detail page you can add sources or destinations, pause them, or remove them. To install the Conversions API snippet, use one of the two options at the bottom:

• Send Document — email installation instructions to your technical team.
• GTM / Frontend Modification Guide — implement the code yourself via Google Tag Manager or a direct frontend change.

Consent Management & Data Privacy

To stay compliant with data protection regulations (GDPR, CCPA, and similar frameworks), only activate tracking scripts after the user has given consent through your Consent Management Platform (CMP). SignalSight respects your consent configuration — events are not sent until consent is granted.
