I am currently using two calls to get all the leads from Unbouce API:
First I get all the pages with callings https://api.unbounce.com/pages
and then download all the leads for a specific landing page with https://api.unbounce.com/pages/{page_id}/leads
.
This however does not return leads acquired through popups and I can’t seem to find any answers in your documentation how to do this as it does not mention popups at all.
