The Twingle Event campaign type represents peer-to-peer events created by users. The campaigns get synchronized between Twingle and CiviCRM in only one direction: from Twingle to CiviCRM. There is no need to synchronize them through the other direction, because usually it is not necessary to change their values. Twingle Events are created by users through a Twingle Project of type event.
You can activate the creation of soft credits for event initiators. In this case a donation by person A will be linked as soft credit to person B which is the event initiator.
