once you need to do once you have added the component to the stage is:
- adding the URL of the pixel in the URL property field
- choose how to trigger it, either by some predefined events or manually, i.e. using the Pixel Loader > Load pixel action in the Event panel, as shown here: https://lh3.googleusercontent.com/l7G9Ksnb24pLYIkWp_zAYZm2sEs9uxbUKLsBCkHiwavIZPtfL-0gv2AveFAMPw=w527)
The list of available events and detailed information about each property are in the help center article you've already seen: https://support.google.com/richmedia/answer/6308134?hl=en-GB, although I just did a quick test and realized that a couple of those event names are not reported correctly:
Interaction should be interaction
PAGE_LOADED should be pageLoaded
I'll ask to update that in the article.
Let us know if something is still not clear!
yes, I'm afraid you'll need to change it to pageLoaded.
You'll easily be able to check it's working correctly previewing the creative in a browser and checking the network calls in the developer tools to see your 1x1 tracker being loaded.
Hope this helps.
