  1. Click the Setup icon, and then select Developer Console.
  2. Click File | New | Apex Class.
  3. Enter a name for the apex class, such as SendEmailToGuest.
  4. Add the apex class code.

    Here’s a sample apex code for an apex class. This code is used to send email confirmation of an appointment when appointments are scheduled by using appointment types with third-party video apps.

    public class SendEmailToGuest {

   @InvocableMethod(label='Send Email To Guest' callout='true')

   public static Void SendEmailToGuestUsingEmailTemplate(List<inputvariables> inputParams)

   {
// Replace this unique name based on the email template used 
       EmailTemplate et = [SELECT Id,Subject, Body FROM EmailTemplate WHERE DeveloperName ='SchedulerUnauthenticatedUserAppointmentTypeEmailTemplateForThirdParty'];
       List<string> toAddress = new List<string>();
       toAddress.add(inputParams.get(0).leadEmail);
       Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

       mail.setTemplateId(et.Id);
       mail.setToAddresses(toAddress);
       mail.setTargetObjectId(inputParams.get(0).leadId);
       mail.setWhatId(inputParams.get(0).appointmentId);
       mail.setSaveAsActivity(false);
       mail.setUseSignature(false);
       List<Messaging.SingleEmailMessage> allmsg = new List<Messaging.SingleEmailMessage>();
       allmsg.add(mail);
       try {
           Messaging.sendEmail(allmsg,false);
           return;
       } catch (Exception e) {
           System.debug(e.getMessage());
       }
   }
    
    public class inputvariables {
        @InvocableVariable
        public String leadEmail;
        @InvocableVariable
        public String leadId;
        @InvocableVariable
        public String appointmentId;
        
    } 
}

    You can replace the Virtual Appointment Email template unique name based on your setup. Here are the available unique template names:

    SchedulerUnauthenticatedUserAppointmentTypeEmailTemplateForAmazonChime
    Email template for confirmation of an appointment when appointments are scheduled by using appointment types with Amazon Chime.
    SchedulerUnauthenticatedUserEngagementChannelEmailTemplateForAmazonChime
    Email template for confirmation of an appointment when appointments are scheduled by using engagement channels with Amazon Chime.
    SchedulerUnauthenticatedUserAppointmentTypeEmailTemplateForThirdParty
    Email template for confirmation of an appointment when appointments are scheduled by using appointment types with third-party video apps.
    SchedulerUnauthenticatedUserEngagementChannelEmailTemplateForThirdParty
    Email template for confirmation of an appointment when appointments are scheduled by using engagement channels with third-party video apps.
  5. Save your changes.

Now, create an Apex action to send email notifications by using the Apex class.
