Hi 

I want to upload  a word document  on Box( External Storage)  using Rest API calls  . 

I am encoding the body in base 64 using Encoding util class but on box the content of uploaded file is in encrypted form .

Is there any other way to send the word /ppt  docs so that the content dont get encrypted on Box( External Storage) ?

 private HttpResponse UploadFile(){
        Document Doc =[Select Body, BodyLength, Id, Name, Type, ContentType From Document ];
        System.debug('Doc' + Doc);
        
  
        
        String p_fileName =doc.Name+'.'+doc.Type;
        String parent_id = '1121945745';
        String boundary = 'AaBbCcX30';
        

        
       String content = 'Content:\r\n--' + Boundary + '\r\n'+'Content-Disposition: form-data; name="files";filename="'+p_fileName+ '"\r\n'+ 'Content-Type:'+doc.ContentType+'\r\n\r\n';
content += '\r\n'+EncodingUtil.base64Encode(Doc.Body)+'\r\n';
content +='--' + Boundary +'\r\n'+'Content-Disposition: form-data; name="parent_id"'+'\r\n\r\n'+'0'+'\r\n' ;
content+= '--' + Boundary + '--\r\n' ;

       

        Http h = new Http();
        HttpRequest req = new HttpRequest();
        string sUrl = 'https://upload.box.com/api/2.0/files/content';
        req.setHeader('Authorization', 'Bearer ' + accessToken);
        req.setHeader('Content-Type','multipart/form-data;boundary='+boundary);
        req.setHeader('Content-Encoding','base64');
       
        req.setEndpoint(sUrl);
        
        req.setMethod('POST');
        req.setBody(content);
        
        HttpResponse res;
        if(!Test.isRunningTest()){
            res = h.send(req);
        }
        else{
             res = new HttpResponse();
        }
        valuetoShow = 'Get Doc: ' + res.getBody(); 
        return res;
      
        
      
    }
