Answer 1

Use [FromBody] before the param. It's check and Get the Property value in body otherwise it's check the Url Querystring.

Example:

[HttpPost]
public JObject AddTag([FromBody] int parentid,[FromBody]string tagname)
{

}

[HttpPost]
public JObject AddTag([FromBody] {ModelName} parent)
{

}
