I have data for the following activities-
I want to know what is the common attribute between these activities through which I can identify that the email which had been send to lead, was opened or clicked later.
I did not get you, My Question is if I have data for "email send" and "email delivered"(from bulk extract API), how would I map this data between this two activities.
Is it the "primaryAttribute" by which we can connect the activity?
And one more thing, is there any document to get details/ meaning of each activity and there respective attributes.
