global class xMattersreq {
  @future(callout=true)
  WebService static void xRESTCall(String endpoint, String payload){
    HttpRequest req = new HttpRequest();
    req.setEndpoint(endpoint);
    req.setMethod('POST');
    req.setBody(payload); 
    req.setHeader( 'Content-Type', 'application/json' );

}

Trigger record on BMCServiceDesk_Incident_c table to fire after inserted uses the xMattersreq class created above to make the HTTP call to the xMatters POST /trigger endpoint.

trigger xMattersAlert on BMCServiceDesk_Incidentc (after insert) {
  string endpoint = 'https://instance.d.xmatters.com/api/integration/1/functions/UUID/triggers';
  string incidentname = '"Incident Name":' + '"' + Trigger.New[0].Name + '"';
  string caseid = '"Case ID":' + '"' + Trigger.New[0].Name + '"';
  string description = '"Description":' + '"' + Trigger.New[0].BMCServiceDeskincidentDescriptionc + '"';
  string priority = '"Priority":' + '"' + Trigger.New[0].BMCServiceDeskImpact_Idc + '"';
  string status = '"Status":' + '"' + Trigger.New[0].BMCServiceDeskStatus_IDc + '"';
  string accountid = Trigger.New[0].BMCServiceDeskFKAccountc;
  string accountidj = '"Account ID":' + '"' + Trigger.New[0].BMCServiceDeskFKAccount_c + '"';
  string recordid = '"ID":' + '"' + Trigger.New[0].Id + '"';

  Account record = [Select Name From Account Where Id = :accountid]; string accountname = '"Account Name":' + '"' + record.Name + '"'; 
  String payload = '{' + recordid + ',' + caseid + ',' + description + ',' + priority + ',' + accountname + ',' + accountidj + ',' + status + '}'; 
  System.Debug( payload) ; 
  xmattersreq.xRESTCall( endpoint, payload );
