Question

Answer
For destinations running in Web Device Mode (where data is sent directly from the browser to the destination's servers), the best way to verify transmission is by using your browser's Developer Tools.
How to verify:
Open your browser's Developer Tools and navigate to the Network tab.
Filter by the name of the destination to see the outbound requests being initiated.
Using Facebook Pixel as an example: when a
pagecall is triggered, you should see an outbound request similar to this.
