I have sucessfully set up a flow that triggers on a new Facebook post, translates it to Arabic, then posts is back to my page. It works brilliantly, the translated post appears in a couple of minutes How soon before LinkedIn integration is available within Flow so I can carry out the same translation on my LinkedIn posts?
I highly recommend creating your own flows from a 'blank flow' rather than using a template as it helps you learn the power of Flow very quickly.
LinkedIn support is something we're planning on, unfortunately, we cannot provide an ETA at this time because the public LinkedIn REST API doesn't contain any of the actions we would want to expose. We are working with the LinkedIn team to get exposing REST APIs booked so we can light it up in Flow. Thank you!
You can now connect to LinkedIn - read more about it here: https://flow.microsoft.com/en-us/blog/q3-2017-update/
