You can send a collection of objects that are Json serialized to a WebAPI action method, which is using encapsulation a basic OO concept. One way to do it is use the DTO pattern.
there is only one payload. but if the payload is json, you just use an array to send more than one employee. the base json can be an array or one of elements. the main restriction is max payload size.
just use an array to send more than one employee --
If I use an array[employees] to send, will I get individual response for each employee or just one response for whole array.
Thanks,

A collection the List<t> is acted upon as a whole. You do know that List<T> a collection is an array. Right? The C# List<t> collection is turned into a Json array when sent.
The List<T> class is the generic equivalent of the ArrayList class. It implements the IList<T> generic interface by using an array whose size is dynamically increased as required. You can add items to a List<T> by using the Add or AddRange methods.
for example, if we are saving employee details, can we save more than one employee in one single post.
You can use a json array to send multiple employee. I made a simple test.
public class User
{
public int Id { get; set; }
public string Name { get; set; }
public string Address { get; set; }
}
[HttpPost]
public void Post([FromBody]List<User> users)
{
}

Yes, Web API's model binder works with complex types.
public ActionResult Index(List<Employee> Employees) { return View(); }Share your code if you need community debugging assistance. Otherwise, try going through the Web API tutorials on this site.

A collection the List<t> is acted upon as a whole. You do know that List<T> a collection is an array. Right? The C# List<t> collection is turned into a Json array when sent.
List<employee> = new List<employee>();

The List<T> class is the generic equivalent of the ArrayList class. It implements the IList<T> generic interface by using an array whose size is dynamically increased as required. You can add items to a List<T> by using the Add or AddRange methods.
The linq shows what is happening.
