Post Request gives a 405 error in Postman - json

Question

on my .Net Web Api, I have an entity model, request model and response model for each database table. When i make a post request to MedTestOrder, i receive a 405 error, but other entities are working fine. I will post code snippets of MedTestOrder entity model, request model, response model, controller and service. The models contain foreign keys and I suspect my error could be from there. I might be wrong or not. I just need help.
1 - Entity Model
namespace Africanbiomedtests.Entities
{
public class MedTestOrder
{
[Key]
public int Id { get; set; }
public int? MedTestId { get; set; }
[ForeignKey("MedTestId")]
public MedTest MedTest { get; set; }
public int? healthcareProviderId { get; set; }
[ForeignKey("healthcareProviderId")]
public HealthcareProvider healthcareProvider { get; set; }
public int? accountId { get; set; }
[ForeignKey("accountId")]
public Account Account { get; set; }
public int? newbornId { get; set; }
[ForeignKey("newbornId")]
public Newborn Newborn { get; set; }
public string PaymentStatus { get; set; }
public Boolean CompletionStatus { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateCompleted { get; set; }
public DateTime? Updated { get; set; }
}
}
2 - Api Request Model
namespace Africanbiomedtests.Models.MedTestsOrder
{
public class MedTestsOrderCreateRequest
{
[Required]
public MedTest MedTest { get; set; }
public HealthcareProvider healthcareProvider { get; set; }
public Account Account { get; set; }
public Newborn Newborn { get; set; }
[Required]
public string PaymentStatus { get; set; }
public Boolean CompletionStatus { get; set; }
[Required]
public DateTime DateCreated { get; set; }
}
}
3 - Response Model
namespace Africanbiomedtests.Models.MedTestsOrder
{
public class MedTestsOrderResponse
{
public int Id { get; set; }
public MedTest MedTest { get; set; }
public HealthcareProvider healthcareProvider { get; set; }
public Account Account { get; set; }
public Newborn Newborn { get; set; }
public string PaymentStatus { get; set; }
public Boolean CompletionStatus { get; set; }
public DateTime DateCreated { get; set; }
public DateTime DateCompleted { get; set; }
}
}
4 - Controller
[Authorize]
[HttpPost("create")]
public ActionResult<MedTestsOrderResponse> Create(MedTestsOrderCreateRequest model)
{
var medTestOrder = _medTestOrderService.Create(model);
return Ok(medTestOrder);
}
5 - Service
public MedTestsOrderResponse Create(MedTestsOrderCreateRequest model)
{
// map model to new account object
var medTestOrder = _mapper.Map<MedTestOrder>(model);
medTestOrder.DateCreated = DateTime.UtcNow;
// save account
_context.MedTestOrder.Add(medTestOrder);
_context.SaveChanges();
return _mapper.Map<MedTestsOrderResponse>(medTestOrder);
}
6 - Postman JSON request
{
"medTestId": 3,
"healthcareProviderId": 3,
"accountId": 1004,
"newbornId": 1,
"paymentStatus": "Complete Payment",
"completionStatus": "1",
"dateCompleted": "01/14/2021"
}
I would really appreciate any help right now

Answer 1

Thank you #Marius and #Karney, I realized i wasn't using the correct endpoint. I needed to add "/create" to my endpoint.

In some cases, your Web API method accepts only PUT requests, Try to put not post.
