How to upload an image or PDF files from smart devices to a specific folder on the server?
A lil' too late for an answer but I was recently facing this one problem and solved by passing the image forward to the procedure and receiving as a blob data type.
Next I did the following:
parm(in:&blob)
&File.Source = &blob.ToString()
&File.Copy('path/to/file.jpeg')
&HTTPClient.AddFile('path/to/file.jpeg')
Hope it still serves you
