REST SERVICE :::

@RestResource(urlMapping='/1.0/Persons/*')

global class SQUser
{    
 @HttpGet

 global static String CheckLead()    
 {   
   String EmailID = RestContext.request.params.get('Email_id');    

   LIST<Lead> ledID = [Select ID from Lead where Email=:EmailID LIMIT 1];     
   LIST<Contact> conID= [Select ID from Contact where Email=:EmailID LIMIT 1];

   if(ledID.size()>0)    
   {    
    return ledID[0].ID;    
   }    
   else if(conID.size()>0)    
   {    
     return 'ContactID '+ conID[0].ID;    
   }     
   else    
   {    
    return 'No record found either for Lead or contact.';    
   }    
 }

 @HttpPost    
 global static String CreateRecord()    
 {    
    Lead ledID = new Lead();    
    ledID.FirstName = RestContext.request.params.get('Fist_nm');    
    ledID.LastName = RestContext.request.params.get('Last_nm');    
    ledID.Phone = RestContext.request.params.get('Phone');    
    ledID.Email = RestContext.request.params.get('Email');    
    ledID.Company= RestContext.request.params.get('Company');

    insert ledID;

    Schema.DisplayType myType = ledID.get(Company).getDescribe().getType();    
    return 'Newly Lead Created ' +ledID.ID;    
 }    
}

Answer 1

Schema.Lead.Company.getDescribe().getType();

You're trying to reference a symbol (company) that doesn't exist.

If you need dynamic code:

Schema.getGlobalDescribe().get(objectName).getDescribe().fields.getMap().get(fieldName).getDescribe().getType();

Where objectName and fieldName are strings, such as 'Lead' and 'Company'.
