Validate Pixel Installation

1. Open an Incognito Window and navigate to your website page where the pixel has been placed.
2. Right-click anywhere on the page and select Inspect to open Chrome DevTools.
3. Click on the Network tab at the top of the developer tools panel.
4. Refresh/reload the page.
5. Use the filter bar () and search for pixel.v2.js in the Network tab search field.
6. Check Response Status: If pixel.v2.js appears in the Network tab with a 200 OK status, this confirms that the browser successfully requested and downloaded the GroundTruth JavaScript file.
   1. Important: A 200 OK response does not confirm that the pixel itself fired or that an event was successfully sent to GroundTruth. It only confirms that the JavaScript file required by the pixel was successfully downloaded and is available for the browser to execute.

Verify That Your Pixel Is Firing

Confirming that the GroundTruth JavaScript file loaded successfully is only the first step. To verify that your pixel is actually firing and sending events to GroundTruth, use the Network tab in Chrome DevTools to look for the event request itself.

1. Open an Incognito Window and navigate to the webpage where the pixel is installed.
2. Right-click anywhere on the page and select Inspect.
3. Select the Network tab.
4. Refresh the page or perform the action that should trigger the event.
5. In the Network Filter bar, enter event.
6. Select the event request and confirm:
   • Request URL: https://vela.groundtruth.com/v2/event
   • Request Method: POST
   • Status Code: 204 No Content

A 204 No Content response confirms that the V2 event request was successfully sent to and accepted by GroundTruth.

Verifying Custom Event Placement

1. Right-click anywhere on the confirmation page where the custom event is placed and select Inspect.
2. Go to the Elements tab to view the live HTML source code.
3. Press Ctrl + F (PC) or Cmd + F (Mac) to open the code search bar at the bottom of the panel.
4. Type gtpx into the search box:
   • The first result will typically be the base pixel script.
   • Click the "Next" arrow in the search bar to find your specific custom event snippet.

5. Ensure the custom event matches the required syntax and label string (e.g., gtpx("conversion",{label: "my_goal_name"})):

   

1. Navigate to the webpage where the legacy pixel has been placed.
2. Right-click anywhere on the page and select Inspect.
3. In the developer tools panel, click on the Network tab.
4. Refresh/reload the page.
5. In the filter bar (), type xad in the Network tab search field.

6. If xad populates as a result and returns a 200 OK or 304 Not Modified status code, this confirms that the browser successfully requested and downloaded the GroundTruth JavaScript file.

   Important: A 200 OK response does not confirm that the pixel itself fired or that an event was successfully sent to GroundTruth. It only confirms that the JavaScript file required by the pixel was successfully downloaded and is available for the browser to execute.

Verify That Your Pixel Is Firing

1. Open the webpage where the legacy pixel is installed.
2. Open Chrome DevTools and select the Network tab.
3. Refresh the page or perform the action that should trigger the event.
4. In the Network Filter bar, enter events.
5. Select the event request and confirm:
   • Request URL: https://engagement-flow-np.groundtruth.com/v1/events
   • Request Method: POST
   • Status Code: 200 OK

A 200 OK response from the /v1/events endpoint confirms that the Legacy Pixel event request was successfully sent to and accepted by GroundTruth.

Important: Do not confuse the status code returned when the browser downloads the GroundTruth JavaScript file with the status code returned by an event request. A 200 OK for pixel.v2.js or the legacy xad JavaScript only confirms that the browser successfully downloaded the JavaScript. To confirm that the pixel is firing, look for the event request described above.
