For e.g., a custom function can be used to create a successor task for a parent task. To achieve this, you will need to create a custom function as given below:

Add the parameters as shown:

Enter the below code in the Deluge editor:

1. dependencyType = "FS";
   values_map = Map();
   values_map.put("name","Task_Name_Here");
   values_map.put("description","Sample Deluge Script For Sub task Creation");
   createTaskResponse = zoho.projects.create(portalId,projectId,"tasks",values_map);
   if(createTaskResponse != null && createTaskResponse.get("tasks") != null)
   {
       taskInfo = createTaskResponse.get("tasks").get(0);
       newTaskId = taskInfo.get("id_string");
       dependencyParam = Map();
       dependencyParam.put("taskid",newTaskId);
       dependencyParam.put("predids",taskId);
       dependencyParam.put("projId",projectId);
       dependencyParam.put("toupdate","dependencyset");
       dependencyParam.put("childprojId",projectId);
       dependencyParam.put("dependencytype",dependencyType);
       info dependencyParam;
       info "------------------";
       projectsAPIEndPoint = "https://projectsapi.zoho.com/restapi";
       dependency = invokeurl
       [
           url :projectsAPIEndPoint + "/portal/" + portalId + "/projects/" + projectId + "/taskdependency/"
           type :POST
           parameters:dependencyParam
           connection:"zprojects"
       ];
       info dependency;
       info "-------------------------------------";
   }
   return "success";
   

Click Save and Execute to run this custom function. You must now associate this function to a Workflow rule and save the rule.

When the criteria is met, the Custom Function will be triggered an a successor task will be created.
