Setting up your Meta Pixel with a first-party domain improves data collection and helps bypass tracking restrictions. This guide shows you how to configure it through Hardal.

Before starting, ensure you have:
- Active Hardal account with a configured signal
- Meta Conversion API Gateway connection set up in Hardal
- Access to your DNS settings

Navigate to your Hardal dashboard and select your signal. Go to **Server Side Hosts** and verify your Meta Conversion API Gateway connection is configured.

Then go to **Settings** > **Setup**. Scroll down to find the specific DNS record details.

Share these DNS record details with your IT team to set up:
- CNAME record pointing to Hardal's infrastructure
- TXT record for verification

Once your IT team confirms the DNS records are set up, navigate to your Signal Gateway dashboard and select your Meta CAPI connection.

Go to **Account Settings** > **Data Routing** and click **Optimize**.

Enter your new CAPI domain (e.g., `capi.yourwebsite.com`) and click **Continue**.

If the DNS records are correctly configured, you'll see a success message.

After a few minutes, check your website to confirm that Meta Pixel and CAPI are working under your first-party domain.

You can verify this by:
1. Opening your browser's developer tools
2. Going to the Network tab
3. Looking for requests to your custom domain (e.g., `capi.yourwebsite.com`)

Your Meta Pixel is now operating through your first-party domain, providing better data accuracy and improved tracking reliability.
