The one I found most suitable is SELECT_CONTENT, but as the doc says:
Select Content event. This general purpose event signifies that a user has selected some content of a certain type in an app. The content can be any object in your app. This event can help you identify popular content and categories of content in your app.
I'm moving my GA events to FB and I wish to keep the comfortable format I have:
screen_name (category) | button_name (action) | value (opt_value)
How can I achieve this? I know I can just create custom events with the screen name and custom param for the button name and value but then my params won't be available in the FB dashboard unless I use the value param which is an int (I need a string) as written here and I'll need to create from advance an audience for every button so I could filter by it later, which is completely not making any sense (!).
Also, I don't want to integrate with BigQuery at the moment.
Thanks.
