Shows String body starting with the words "PublishedParameters" is that required?
The reason I ask is that there is another download example with an HTML form that takes in simple value pair inputs with out the "PublishedParameters" label or title of the json.
String body = "{\\n" +
" \\"publishedParameters\\" : [\\n" +
" {\\n" +
" \\"name\\" : \\"MAXY\\",\\n" +
" \\"value\\" : \\"42\\"\\n" +
" },\\n" +
" {\\n" +
