Fetching /searchrss from external application (Zapier) not working

I'm trying to fetch the URL /searchrss?q=hello&sort=date%20desc

  • When I am logged into Telligent I can get results.
  • When I use Zapier (with username/password) there are no results.
  • When I use curl with a username/password there are no results.

Does the RSS feed use Basic auth, or does it require something else?
