REST API Intergartion with the other server(By using the Endpoint)

Hello Everyone,

I have given the Endpoint whenever the records are inserted in salesforce.com,i need to get the values from end point in JSON format
and by using External id i need to get that json values and update in salesforce.com
I wrote the trigger to insitate the webservice class
trigger AccountCallout on Account (after insert)
{

    for (Account a : Trigger.new) {
        // make the asynchronous web service callout
        WebServiceCallout.sendNotification(a.Name);
    }

}

and this webservice class is
public class WebServiceCallout {

    @future (callout=true)
   
    public static void sendNotification(String folionum) {
   
         folionum='484307021840';
        HttpRequest req = new HttpRequest();
        HttpResponse res = new HttpResponse();
        Http http = new Http();
        req.setHeader('content-type', 'application/json; charset=utf-8');
        req.setEndpoint('http://abc.cloud.net/api/values');
        req.setMethod('POST');
        req.setTimeout(60000);
        req.setBody('folionum='+EncodingUtil.urlEncode(folionum, 'UTF-8'));
         String jsonData = res.getBody();
        req.setCompressed(true); // otherwise we hit a limit of 32000
        System.debug(res.toString());
        System.debug('STATUS:'+res.getStatus());
        System.debug('STATUS_CODE:'+res.getStatusCode());    
        try
         {
              res = http.send(req);
          }catch(System.CalloutException e)
           {
             System.debug('Callout error: '+ e);
             System.debug(res.toString());
           }

    }
   
}
when i check teh logs i get the error has

System.HttpRequest[Endpoint=http://abc.cloud.net/api/values, Method=POST]
20:24:21.928 (4928855000)|CALLOUT_RESPONSE|[22]|System.HttpResponse[Status=Internal Server Error, StatusCode=500]

It says Internal Server Error. Is there any error number in the debug logs.
If there is then you may have to contact Salesforce with the Error number so they may be able to find out the exact reason.
