Campaigns are created through contactLists rather than external contacts, so I want to clarify that I mean "contactId", not "externalContactId".
I have requirements to gather the information of all the contacts we called during a campaign. Specifically I need to grab the time the call disconnected, the wrap-up code, and an identifier for the contact we called.
I know it is possible to get the first two, but I am unsure of how I can get an identifier for the contacts. Contacts can have custom columns, is there a way we can link a customer whom we called back to a contact in our contact list so we can identify exactly who we called?
ParticipantId comes back from the GET /api/v2/conversations/calls/history and the POST/api/v2/analytics/conversations/details/query endpoints, but participantID is unique to every conversation so it would not link back to a contactID.
Is this possible? Thanks!
