How to post data to custom API via Ajax on Synfusion Angular Scheduler

Question

I'm currently trying to figure out how to post data to my API when an event is created using the editor window. I use Ajax to retrieve content already as shown below;

const ajax: Ajax = new Ajax(
  "https://localhost:3486/api/CalendarEvents?StartDate=" + startDate + "&EndDate=" + endDate,
  "GET",
  true
);
ajax.send().then();
ajax.onSuccess = (data: string): void =>
{
  this.scheduler.eventSettings = {
    dataSource: JSON.parse(data).map((value, index) => ({
      id: index,
      Subject: value.title,
      StartTime: value.startDate,
      EndTime: value.startDate
    })),
    fields: {
    }
  };
};
ajax.onFailure = (): void  =>
{

};

Furthermore, how do I get the currently selected date range when the user changes the date on the scheduler via view or date navigation.

onActionComplete(args: ActionEventArgs): void {
    if (args.requestType == "dateNavigate") {
      // how to get current date range ?
    }
}

[UPDATE] Found how to get the currently selected date range:

onActionComplete(args: ActionEventArgs): void {
    if (args.requestType === "viewNavigate" || args.requestType === "dateNavigate") {
      const currentDates: Date[] = this.scheduleObj.getCurrentViewDates();
      const startDate = currentDates[0];
      const endDate = currentDates[currentDates.length - 1];
    }
  }
