Update Task API Limit Issue

Update Task API Limit Issue

I am running into issues with the API limit for update task in Zoho Projects. 

In a typical Project, we have 120-130 Tasks and I would like a field change made to the Project to propagate down to all Tasks that belong to the Project. (In this case "Territory). I am running the below function upon field change of Project.Territory to update Task.Territory.

Is there any reasonable way to get around the 100x API usage limit for this function?

  2. // Get all tasks for the specified project ID
  3. taskDetails = zoho.projects.getRecords(portalId,projectId,"tasks",0,0,"xxxxxxxxxx");
  4. tasksList = taskDetails.get("tasks");
  5. // Create a map to specify the custom field update
  6. customFieldsMap = Map();
  7. customFieldsMap.put("UDF_CHAR82",territory);
  8. // Create the main map and nest the custom fields map within "custom_fields"
  9. updateTaskParameter = Map();
  10. updateTaskParameter.put("custom_fields",customFieldsMap);
  11. //only run code if Project.Territory is not null
  12. if(territory != null)
  13. {
  14. // Loop through each task in taskDetails (Tasks belonging to projectId)
  15. for each  task in tasksList
  16. {
  17. // Access the ID of each task and Territory (UDF_CHAR82) 
  18. taskId = task.get("id");
  19. taskTerr = task.get("UDF_CHAR82");
  20. //Check if Task has subtasks
  21. taskisParent = task.get("isparent");
  22. // If Task has Subtasks get all Subtasks belonging to this Task
  23. if(taskisParent == TRUE)
  24. {
  25. subTaskResponse = invokeurl
  26. [
  27. url :projectsAPIEndPoint + "/portal/" + portalId + "/projects/" + projectId + "/tasks/" + taskId + "/subtasks/"
  28. type :GET
  29. connection:"xxxxxxxxxx"
  30. ];
  31. //For each Subtask belonging to this task update Territory if not already matching
  32. for each  subTask in subTaskResponse.get("tasks")
  33. {
  34. // Access the ID of each task and Territory (UDF_CHAR82) 
  35. subtaskId = subTask.get("id");
  36. subtaskTerr = subTask.get("UDF_CHAR82");
  37. if(subtaskTerr.toString() != territory.toString())
  38. {
  39. subtaskUpdate = zoho.projects.update(portalId,projectId,"Tasks",subtaskId,updateTaskParameter,"xxxxxxxxxx");
  40. }
  41. }
  42. }
  43. // Perform the update operation if Task.Territory differs from Project.Territory
  44. if(taskTerr.toString() != territory.toString())
  45. {
  46. taskUpdate = zoho.projects.update(portalId,projectId,"Tasks",taskId,updateTaskParameter,"xxxxxxxxxx");
  47. }
  48. }
  49. }
  50. return taskUpdate;
