I am looking to implement Event ID serialization on my website however I am curious at how Event ID serializations works in the data feeds and other data?
For example if I create a hit that contains a hit with the following:
Which the visitor later returns to with a different evar20:
Would the entirety of the second hit be ignored (meaning the updated evar would not be seen) or just the serialized event?
For serialized events only the event value is ignored. Other attributes in the hit are counted. This is not clearly documented, however, this is how I have seen the hits with duplicate events are processed.
