problem

when pass id value of put(update) from postman it passed as 0 although it have value on link ?

i select key from post man as contenttype application/json

and this is my url

https://localhost:44326/api/Employee/put?id=5

and when put breakpoint in function put and run app

it hit breakpoint but id return with 0 although i have 5 in my link

and 5 also exist on database 

  [Produces("application/json")]
    [Route("api/Employee")]
    public class EmployeeController : Controller
    {
[HttpPut("{id}")]
        public IActionResult PutEmployee(int id, [FromBody] Employee employee)
        {
                if (id != employee.EmployeeId)
            {
                return BadRequest();
            }

           

            try
            {
                _repository.Update(employee);
            }
            catch (DbUpdateConcurrencyException)
            {
                if (!EmployeeExists(id))
                {
                    return NotFound();
                }
                else
                {
                    throw;
                }
            }

            return Ok();
        }

when run API update from angular 6 it give me bad request because id is passing by 0 ?

why is pass id as 0 and how to solve this problem ?

I work with asp.net core 2.1 visual studio 2017

and I have this function above on controller Employee

this is only function update (put) for my controller 

so that how to solve problem passing 0 and 

what is correct link if above is wrong ?
