Send emails through messaging API via HTTP instead of the Sitecore OOTB CustomSMTP

How to send email over HTTP by leveraging Sitecore EXM features?

Config changes:

File Path : \App_Config\Sitecore\EmailExperience\Sitecore.EmailExperience.ContentManagement.config

       1. Comment out existing processor

                    <!-- <processor type="Sitecore.EmailCampaign.Cm.Pipelines.SendEmail.SendEmail, Sitecore.EmailCampaign.Cm" resolve="true" /> -->

        2. Add your new processor(which will hold external API calling logic)

                    <processor type="Foundation.Notification.Pipelines.ExmSendEmailProcessor, Foundation.Notification" resolve="true" />

<SendEmail>

        <processor type="Sitecore.EmailCampaign.Cm.Pipelines.SendEmail.FillEmail, Sitecore.EmailCampaign.Cm" resolve="true" />

        <!-- <processor type="Sitecore.EmailCampaign.Cm.Pipelines.SendEmail.SendEmail, Sitecore.EmailCampaign.Cm" resolve="true" /> -->

		<processor type="Foundation.Notification.Pipelines.ExmSendEmailProcessor, Foundation.Notification" resolve="true" />

        <processor type="Sitecore.EmailCampaign.Cm.Pipelines.SendEmail.Sleep, Sitecore.EmailCampaign.Cm">

              <!-- Number of milliseconds to put the thread to sleep for after an email has been sent. -->

              <param desc="sleep">50</param>

          </processor>

      </SendEmail>

Pipeline/Processor logic:
Call external API and pass the required details.
public class ExmSendEmailProcessor
    {
        public void Process(SendMessageArgs args)
        {
            Assert.ArgumentNotNull((object)args, nameof(args));
            MailNotification mailNotification = new MailNotification();
            if (!(args.CustomData["EmailMessage"] is EmailMessage message))
                args.AddMessage("Missing EmailMessage from arguments.");
            else if (message.Recipients.Count < 1)
                args.AddMessage("Missing Recipients from EmailMessage argument.");
            else
            {
                CommunicationModel model = new CommunicationModel();
                model.To = string.Join(",", message.Recipients);
                Logger.ABCLogger.Info($"EXM-model.To : {model.To}");
                model.NotifyContent = message.HtmlBody;
                Logger.ABCLogger.Info($"EXM-model.NotifyContent : {message.HtmlBody}");
                model.Subject = message.Subject;
                Logger.ABCLogger.Info($"EXM-model.Subject : {message.Subject}");
                model.From = message.FromAddress;
                Logger.ABCLogger.Info($"EXM-model.From : {message.FromAddress}");
                bool status = mailNotification.Notify(model);
                Logger.ABCLogger.Info($"mailNotification.Notify(model) status : {status}");
            
            //Call the external api and pass required details

            }
        }
    }

Publishing Folder Programmatically-Using Sitecore Scheduling agent

 How to publish multiple folders/root items using Sitecore scheduling Agent?

Solution:  Use the code below…

public void Run()

{

    // set publish options

    Database sourceDatabase = Sitecore.Configuration.Factory.GetDatabase("master");




    Item settingItem = sourceDatabase.GetItem("/sitecore/content/

PublishContentFolderSetting");

    var folderList = settingItem.GetMultiListValueItems("FolderList");




    var TargetDbList = settingItem.GetMultiListValueItems("TargetDatabaseList");

    foreach(var targetDb in TargetDbList)

    {

        foreach(var folderPath in folderList)

        {

            Database targetDatabase = Factory.GetDatabase(targetDb.Fields["Target database"].Value);




            PublishOptions myOptions = new PublishOptions(sourceDatabase, targetDatabase,

PublishMode.Smart,

Sitecore.Data.Managers.LanguageManager.DefaultLanguage, DateTime.Now);

            myOptions.RootItem = sourceDatabase.Items[folderPath.Paths.Path];

            myOptions.Deep = true;




            Publisher myPublisher = new Publisher(myOptions);

            // publish in AsyncMode




            var myPublishJob = myPublisher.PublishAsync();

            // publish in SyncMode




            myPublishJob.Start();

        }

 }  

}
