The EveryAction connector only allows you to sync gifts from EA to RENXT. It would be helpful the option to push giving history to EA as well. It says you can map gift queries and gift lists from RE, but the only endpoints in EA are for people.

Within the EA API, there are endpoints for posting contributions and bulk uploads, implying that Omatic could implement this feature to create a true bi-directional sync.
