Marketing Event API. Where to find 'ExternalEventId' and the 'ExternalAccountId'

[LHarney]

Hi,

I am using the marketing event API. I integrated the Eventbrite app and when I create an event on Eventbrite it is synced with HubSpot.

I am trying to create and get marketing events using the Marketing Event API.
Could you clarify where I can find 'ExternalEventId' and the 'ExternalAccountId'. Nothing seems to work.

Thanks.
