A very silly mistake was done : I added a line
CURLOPT_POSTFIELDS => $raw_data,
and few lines below I added
CURLOPT_POSTFIELDS => $request,
My values for the raw Data are in $raw_data, thus $request was over-writing that.Just need to comment the line :
CURLOPT_POSTFIELDS => $request,
and it works great!
