Kendo Scheduler - Read datasource - Post array of strings to Web API

Question

I am trying to accomplish following, get appointments of a user through POST request as I need to post other calendar ids to get appointments of other users as well. The POST request is sent to a Web API. The endpoint gets hit but the array of calendarIds is always empty.

This is the datasource definition:

dataSource: new kendo.data.SchedulerDataSource({
                batch: true,
                transport: {
                    read: {
                        url: "/api/MyCalendar/GetAppointments",
                        dataType: "json",
                        type: "POST"
                    },
                    parameterMap: function(data, type) {
                        if (type === "read") {
                            return JSON.stringify(data);
                        }
                    }
                }

This is the Web API implementation:

[HttpPost]
        public HttpResponseMessage GetAppointments(string[] calendarIds)
        {

// calendarIds is always empty

This the request posted content (textView) from fiddler:

{"calendarIds":["1c78e75f-9516-42cf-a439-271ee997abf1"]}

I am not sure what is wrong in here, thanks for any help on this.

Update:

{"calendarIds":["1c78e75f-9516-42cf-a439-271ee997abf1"]}

You may try annotating your WebAPI post method with [FromBody] attribute

    [HttpPost]
    public HttpResponseMessage GetAppointments([FromBody]string[] calendarIds)

Also make sure you are passing in an Array in the request body instead of an Object. What you are sending right now {"calendarIds":["1c78e75f-9516-42cf-a439-271ee997abf1"]} is an object whereas the WebAPI method accepts an Array

You can try:

    parameterMap: function(data, type) {
                      if (type === "read") {
                          var values = data.calendarIds.split(','),
                          return JSON.stringify(values);
                      }
                  }
