If your REST API need return a file to the client download, this is the source code that you could write (P.S.: extracted from the question https://community.intersystems.com/post/download-file-rest and its responses):

Set %response.ContentType = "image/jpeg"

Do %response.SetHeader("Content-Disposition","attachment;filename=""test.jpg""")

Set %response.NoCharSetConvert=1

Set %response.Headers("Access-Control-Allow-Origin")="*"

Set stream=##class(%Stream.FileBinary).%New()

Set sc=stream.LinkToFile("/opt/irisbuild/output/test.jpg")

Do stream.OutputToDevice()

Set tSC=$$$OK
