Tried searching for this but couldn't find anything on it and I'm relatively new to the API.
If I already have a Campaign ID logged (imported HTML into CM via the API and stored the response) - then I can obviously detect when that campaign is sent. Is there any way though to detect if it's subsequently Resent? Basically to get the new Campaign IDs from the Resends to query them as well?
There isn't a way to know if a particular campaign was 'edit and resended' using the API, but you can request a list, including the IDs, of all of the campaigns sent within a particular client account:
