"Text is Required" posting message with text

[Michael Hagesfeld]

I am submitting the following:
{ "text": "Testing From Mike", "source_guid": "635d53d0-f7d8-4824-b469-f0c3dfabd064" }

and getting the following response:

{"meta":{"code":400,"errors":["text is required"]}} 

I have seen a couple similar posts, but none with an answer - anyone have an idea? 

Thanks,

Mike

SOLVED - answer, as usual, re-read the manual :)  I needed to wrap it in a message:

    "message": {

    "text": "Testing From Mike",

    "source_guid": "29bfb088-e792-455b-879b-244186d89023"    

    }
