We use Power Automate with workflows within Workfront. I wasn't involved in the setup, but it works pretty nicely. What information are you looking for?
Power Automate does not have any pre-built connectors for Workfront. We use the Workfront API in a custom connector. Our custom connector was built by a developer at a third party consultant - PowerApps911.
Hi - I'm no means a developer so the custom connector was a ton of trial and error and even then, I could only get an action created (Still haven't gotten Triggers to works).
However, Power Automate also does HTTP calls. So I've been playing around with that a little, but you can use only really use that for more static calls.
Like I have one where I wanted to get items updated after Sept 30th on a certain project
