Expose more member data in CSV exports or Admin API

Ideas

It would be great if the additional data points attached to members inside of Ghost was exposed in CSV exports or even the Ghost API. I’ve noticed a couple of data points:

  • utm_source: This actually seems to work as if you load a subscribe page with ?utm_source=testing added to the end of the URL and subscribe the member has “Source: Testing” applied to their “Signup info”
  • Integration source: Again this appears under “Source” but it’s not a UTM tracking code it’s actually an integration
  • Page source: This also appears under “Signup info” and it even a link

I’m already seeing the “labels” feature in Ghost getting abused to expose the above data points in CSV exports, so I think it’s a valid request to get these to appear in exports or in the Admin API. Thanks!
