trigger Accountrigger on Account (before update) {
             if(Trigger.Isupdate && Trigger.IsBefore)
    {  
            for (Account Acc:Trigger.new)
            {
              SenddataRequest();
              }
    }      
}

Get the complete information for the "Epson 0xf1" error and know how to fix the problem on your printer. Because the error related to the software/hardware on your PC/printer both.

Hi Himanshu,

Please  update in Apexclass last function public instead of private 
  
public static SenddataRequest getInstance(){
         
    if(instance == null){
	  instance = new SenddataRequest();
	} 
		return instance;
	 }

if you need any assistanse, Please let me know!!

Thanks Mukesh, I have marked it Public which allowed me to Save Trigger. However i am getting Call out error now. 
'Callout from triggers are currently not supported' error
When i am trying to do  @future (callout=true), it's not allowing. Do you know what's best way to do @Future with Constructor.

I need to do Call out because Apex class is trying to connect external endpoint as REST API which is mentioned in Consturctor "private SenddataRequest()"

Hi Himanshu,
  
public class SenddataRequest {
    
    public class requestWrapper
    {  }
    
    public String GetAccounts(Account a)
    {  return 'Hello'; }
    
    public SenddataRequest(){
        makeCallouts();
    }
    

@future(callout=true)
public static void makeCallouts()
{
    system.debug('Called makecallouts method');
}

}
