We have just setup Event Notification Service and a callBack URL. I know how to tie messages called from the Transactional Messaging service, via the definitionKey. However, for other messaging that is initiated from MC itself, how can I tie messages back to a subscriber where there is no subscriberKey or message ID included?
Heres a sample of data that is returned:
info Message Key: Eid: xxxxxxxx Mid:xxxxxxxx Channel:email Composite Batch ID:61 composite List ID:60 Composite Sub ID:213995105 Info lp Address: xxx.xx.xxx.xx user agent: Outlook-iOS/725.4611018.prod.iphone (4.38.0) Composite ID:273618.104.22.168995105 Definition ID:NA Definition Key: NA Event Category Type: EngagementEvents.EmailOpen Status: Subscriber Key: To: Timestamp: 1590109543000
If anyone has any ideas about the fields that are returned then please let me know.
