Im trying to send an JSONObject over HTTPPost, however now Im receiving a 400 error.<\/p>\n
I’ve been going through with the server coder, and making smaller and more concise calls with a less complicated JSON object, however I still receive the same 400 error.<\/p>\n
How do I go about fixing it?<\/p>\n
