The activities/leadschanges endpoint "Returns a list of Data Value Changes and New Lead activities after a given datetime", as the documentation says: (http://developers.marketo.com/rest-api/endpoint-reference/lead-database-endpoint-reference/#!/Activities/getLeadChangesU…)
That seems to mean that a Lead has been run through some activity and that some of its values has been updated. My question is: Does it means when that happens that the Lead has been updated? Can we say it?
A lead has a creation date as well as an updating date. The updated date of a lead, should match some row in the activities/leadschanges results. Is that a correct asumption?
What I'm trying to do is getting just the leads that have been updated in a time range. So, I request getLeadsChanges endpoint for that time range, extract the lead IDs and ensure they are unique, and then I query those lead IDs to get a bigger picture of them. Does it make any sense?
