I'm sure this is a very novice question, but is there a way to require an attachment on a form before allowing the user to select a field picklist value of closed won?

I was wondering if it was possible to create a workflow for an automation email to a checkbox field when it is changed (Checked/ Unchecked)

global class customerbatch implements Database.Batchable<sobject>
{
    public String myname;
    global customerbatch(String myname)
    {
        this.myname=myname;
    }
    global Database.QueryLocator start(Database.BatchableContext bc)
    {
        return Database.getQueryLocator('select id,AType__c from Customer__C where name='+myname);
    }
    global void execute(Database.BatchableContext bc,list<customer__c> scope)
    {
        list<Customer__c> cust=new List<Customer__c>();
        for(Customer__c c:cust)
        {
            c.AType__c='saving';
            cust.add(c);
        
        }
        update cust;
    }
        global void finish(Database.BatchableContext bc)
        {
            Messaging.singleEmailMessage myemail=new Messaging.singleEmailMessage();
            String[] toadd=new String[]{'penchalaraju7@gmail.com'};
            myemail.setToAddresses(toadd);
            myemail.setSubject('my notification');
            messaging.sendEmail(new messaging.Email[]{myemail});
            
        }
    
}

I have a requirement to retrieve a selected user's calendar on a visualforce page. Can anyone help ?

this is my trigger

      }

so,plz help me with the code.

I noticed a spike of api calls by one of the user in our Salesforce org. I wanted to understand that for the given user, can we get the source as in what app consumed these api calls under this user. So that i can know that what app on Salesforce is consuming these api and take a valid action to stop or reconfigure the source to use the api's.

Any help is appreciated!
Thanks

Can someone help me identify what is chewing up our API calls? As of 3 days ago, we started hitting our 20K limit every day, and prior to that we'd barely hit 1000. I've turned off all our coded integrations, and we're still hitting 20k. I looked at the SF reports, but they only tell me # of API calls by user. How can I see what the API calls are and where they are coming from to help me track down where the leak is???
