При запросе на API через Postman, в параметр метода приходит 0, вместо переданного значения

Вот сам метод контроллера:

    [HttpPost("verify")]
    public async Task<IActionResult> VerifyAccount(int verifyCode)
    {
        string? Email = HttpContext.Session.GetString("Email");
        string? Password = HttpContext.Session.GetString("Password");
        string? Username = HttpContext.Session.GetString("Username");
        string? Role = HttpContext.Session.GetString("Role");

        if (Email is null || Password is null || Username is null || Role is null)
            return StatusCode(422, new { message = AccountErrorMessage.NullUserData });

        string? code = HttpContext.Session.GetString(Email);
        if (string.IsNullOrWhiteSpace(code))
            return StatusCode(422, new { message = AccountErrorMessage.VerifyCodeNull });

        try
        {
            int correctCode = int.Parse(code);

            if (!_validation.IsSixDigit(correctCode))
                return StatusCode(500, new { message = AccountErrorMessage.Error });

            if (!verifyCode.Equals(correctCode))
                return StatusCode(422, new { message = AccountErrorMessage.CodeIncorrect });

            var userModel = new UserModel { email = Email, password_hash = Password, username = Username, role = Role };
            await _userCreate.Create(userModel);

            HttpContext.Session.Remove(Email);
            HttpContext.Session.Remove("Email");
            HttpContext.Session.Remove("Password");
            HttpContext.Session.Remove("Username");
            HttpContext.Session.Remove("Role");

            return StatusCode(201);
        }
        catch (FormatException)
        {
            return StatusCode(422, new { message = AccountErrorMessage.InvalidFormatCode });
        }
        catch (Exception ex)
        {
            _logger.LogCritical(ex.ToString());

            HttpContext.Session.Remove(Email);
            HttpContext.Session.Remove("Email");
            HttpContext.Session.Remove("Password");
            HttpContext.Session.Remove("Username");

            return StatusCode(500, new { message = AccountErrorMessage.Error });
        }
    }
