Editing Pixels

You can easily edit your conversion pixel by opening a published campaign. This can be done by pressing the cogwheel next to the campaign and clicking on Open. Once inside the campaign report, you need to go to Settings and choose the Advanced tab. There you'll see the Edit pixel button, right beside your main conversion pixel. 

Once you've clicked on that button, you'll see this screen. Here you can easily edit the pixel event in case you want to change it.
