Issue

When viewing the event delivery or delivery overview in the Segment UI for client-side events in destinations such as Reddit Pixel, all events appear as filtered, even when the events are explicitly mapped and enabled.

Product

Twilio Segment 

Environment

Segment Console

Cause

This behavior is expected for client-side (device-mode) integrations. Because client-side destinations send data directly from the browser SDK to the destination's endpoints, the data completely bypasses Segment's server-side delivery tracking pipeline. Consequently, the Segment UI cannot track the downstream server delivery and marks these events as filtered or omitted within the server-side delivery logs.

Resolution

To confirm that your events are being successfully delivered to your downstream destinations, you must verify the data transmission directly from the client side:

1. Open your website in a web browser.

2. Open the browser's Developer Tools by pressing F12 or right-clicking the page and selecting Inspect.

3. Navigate to the Network tab.

4. Trigger the event on your website.

5. Look for the network requests being sent directly to the destination provider (e.g., Reddit, Facebook) to confirm that the event payload is leaving the browser successfully.

6. Alternatively, log into the specific destination's platform to verify real-time data receipt in their native dashboards.

If the network calls are firing successfully or data is appearing within the destination's dashboard, the filtered status in the Segment UI can be safely ignored.
