Event tracking with GUID in value field

Question

Does the value have to be numeric, I am trying to store unique Ids (strings) in the value field, but when I look at the reports only a zero (0) value is being stored.

here is example of issue:

 "type": "event",
        "eventCategory": "Online-Ordering-Menu",
        "eventAction": "ItemAddToCart",
        "eventName": "ItemId",
        "eventValue": 0  -- I want this be value of the Item which is type GUID structure '4eb3f8ba-6bf2-414b-8146-b75bce6a283f'

is it possible to store that value?

After Reading through the documentation and not rushing a found the answer i was looking for

Answer 1

The event value has to be numeric, but you should be able to store what you want by storing the data in the eventName.

It will log an event with an event category (Videos, Music, Games…), an event action (Play, Pause, Duration, Add Playlist, Downloaded, Clicked…), and an optional event name and optional numeric value.
