Answer 1

if you are json

application/atom+json;charset=utf-8

if your xml means try this

$headers = array('Content-Type: application/atom+xml; charset=utf-8',
'Content-Length: '. strlen($xml),
'Authorization: GoogleLogin '. trim($authToken)),
'Connection: close');

For more information:

or

check your xml document tag

<!-- Correct -->
<?xml version="1.0" encoding="utf-8"?>
