i have a workflow where i want to import the latest fit file i uploaded to Intervals (from MyWhoosh, Zwift etc) into an app on my iPhone (Healthfit), i was using some convoluted way to do this so i made a shortcut, im not sure its very efficient but i tested it and it seems to work properly on my phone, if its useful to you great, if not, move on 
otherwise if you make it better let me know 
hopefully im not breaking any rules around api access for example, if i am please let me know so i can change what ever is needed
