I am sending the following HTTP request:

In my code, I am sending it using UART tx requests to the xbee module, for which the translates to:
POST /input/8dZ8bgapvjfYzmwWno6Wr.txt HTTP/1.1\r\n
Host: data.sparkfun.com\r\n
Phant-Private-Key: pz5ga4pkydHgpEb8v608\r\n
Connection: close\r\n
Content-Type: application/x-www-form-urlencoded\r\n
Content-Length: 7\r\n
\r\n
temp=44
This is to communicate to the phant dataserver at data.sparkfun.com, and it responds with the following data:
HTTP/1.0 400 Bad request
Cache-Control: no-cache
Connection: close
Content-Type: text/html
<html><body><h1>400 Bad request</h1>

I found the answer: The packet is correct. While configuring the Xbee Wifi module using XCTU, I had to give the correct port numbers of the server and client Xbee, which were wrong. Server was 80, client was any port I think.
