Getting Bad Request from a HTTPAPI call

Hi,

I am trying to Post to a URL with a username and password to get a token
back using HTTPAPI and YAJL and am getting BAD_REQUEST error. I have also
tried using the following instead of using the yajl set of commands to
generate the JSON-
myJson = '{ "grant_type": "client_credentials" }';

When I debug and check the contents of myJSON, I get junk values-
MYJSON =
....5...10...15...20...25...30...35...40...45
1 'ÅÊ/>ȬÈ`øÁÄ%ÑÁ>ȬÄÊÁÀÁ>ÈÑ/%Ë'

Can someone please help?
