Web services SOAP错误：未满足安全要求，因为传入消息中不存在安全标头

我正在尝试使用exacttarget提供的SOAP wsdl将salesforce与exacttarget集成

我能够生成apex类，但在调用create请求时，我得到了错误System.callout异常：Web服务callout失败

由于我是apex的新手，我不确定SOAP头请求是否只能通过http完成？或者我可以通过我的课堂来做

请在下面找到我正在使用的代码

//String myData = 'smruti.bhargava@accenture.com.etdev:smruti@123';
//authentication = EncodingUtil.base64Encode(Blob.valueOf(myData));
soapReq.inputHttpHeaders_x.put('Authorization','Basic ' + authentication );SALESFORCE STUB
