Hi,
If Campaign is fully hosted by Adobe then talk to Support about getting an sftp login. They should also give you the local server path to write files to for pickup.
If not fully hosted, talk to local IT about setting up sftp+whitelisting with the goal of getting sftp users with read access to a folder on the primary Campaign app server (bonus for having the folder shared across app servers).
If you'd rather not talk to anyone, files can be written to /usr/local/neolane/nl6/datakit/xtk/eng/img or similar and picked up at http://<host>/xtk/img/report.pdf in a web browser.
Thanks,
-Jon
