Unable to use Mail API in node js

Unable to use Mail API in node js

var options = {
host: 'mail.zoho.com',
path: '/api/accounts/4551522000000XXXXXX/messages',
header: {
'Authorization' : 'Zoho-authtoken 9cb09784703XXXXXXXXXXXXXXXXXXXX',
'Content-Type' : 'application/json'
},
method: 'POST'
};
var dd = {
"fromAddress" : "no-reply@xxxxxx.com",
"toAddress" : "pranjal.pranz@gmail.com",
"subject" : "Email - Always and Forever",
"content" : "Email can never be dead. The most neutral and effective way, that can be used for one to many and two way communication."
};
                          reqt = http. request( options, function( resp) {
console. log( 'STATUS: ' + resp. statusCode);
console. log( 'HEADERS: ' + JSON. stringify( resp. headers));
resp. setEncoding( 'utf8');
var body = '';
resp. on( 'data', function ( chunk) {
console. log( 'BODY: ' + chunk);
body += chunk;
});
resp. on( 'end', () => {
postResponse( res, 200, false, body);
});
resp. on( 'error', ( err) => {
postResponse( res, 400, true, { "m" : "m2" , "error" : err});
});
});
reqt. on( 'error', ( err) => {
postResponse( res, 400, true, { "m" : "m1" , "error" : err});
})
reqt. write( querystring. stringify( dd));
reqt. end();



I am getting 301 permanently removed when calling this api. Whats wrong and how to implement it?
