Upon successful event/ticket action creation through the Stream endpoint, an actionPromise will be issued and returned. Use it to query it's status:

waiting_broadcastAction is still waiting in queue to get broadcast on chain
pendingAction was broadcast and is waiting confirmation
confirmedAction was broadcast and successfully confirmed
errorAction was broadcast on chain but an error occurred
wont_broadcastAction was invalid (e.g. selling ticket on non existent event) and a broadcast on chain won't be attempted
no_broadcast_requiredSome actions might not need a broadcast on chain-at all e.g. updateTicket
