I didn't see anything existing for this.
Would be nice to be able to pop URLs over to Bit.ly or Rebrandly and get a branded or just shortened link back to send to the user.
For now, I'll see if I can do this manually with the Code section.
We don't have any link shorteners, although supporting a few of them would definitely be a good idea.
In the meantime I'd try using a HTTP request rather than going for the code service as you can probably access their API using a straight web request?
Good call @johnjackson , I'll give that a try.
I made a shared Flow for this, in case anyone else finds this useful.
You'll need your own Bit.ly access token (it's free, just have to set up an account)
