Sample Code to send the request::::::::
HttpRequest req1 = new HttpRequest();
req1.setEndpoint('https://accept.authorize.net/payment/payment');
req1.setHeader('Authorization', 'Bearer '+accTokn);
req1.setHeader('Content-Type', 'application/json');
req1.setHeader('Content-Length', '0');
//req1.ContentLength = 0;
req1.setMethod('POST');
//req1.setBody(json);
System.debug('request body::'+json);
Http h1 = new Http();
// Send the request, and return a response
HttpResponse res1 = new HttpResponse();
system.debug('req body############'+req1);
res1 = h1.send(req1);
String responseBody1 = res1.getBody();
