(Solved) Bad request on Business Event

I am receiving the following error when submitting a business event:

05-14 17:39:54.984: I/Corona(23276): GA: Submitting custom event(s): 'business': { area='game-store', eventID='Purchased:100gp', currency='USD', amount='99' } - Server response: Bad request

Am I missing some parameters?

My request is:

gameAnalyticsObj.newEvent (eventype, evenTable)

where

eventType= business eventTable[eventID]= Purchased:100gp eventTable[currency]= USD eventTable[amount]= 99

Ops. My bad. I am passing “eventID”  instead of  “event_id”.
