REST API copy file requests now support “file in group” URL as a
source parameter. Previously you had to know the individual file UUID or URL.
For example, now you can do this:
$ curl -X POST \ -H "Authorization: Uploadcare.Simple demopublickey:demoprivatekey" \ -d "source=https://ucarecdn.com/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx~10/nth/5/" \ -d "store=true" \ "https://api.uploadcare.com/files/"
