Hey, I'm looking for a field that is called 'send key' or something. I'm pulling data out of Marketo via the API and I'm seeing a field 'email_campaign_external_key' which is filled. I'd like to use that to stich data but I need to be able to see this field in the UI as well so that the email team can store that key on their end as well. Anyone know where I could find that? Secondly, would that key be generated before the email is sent?   Thanks ... View more
