If you are using appseting.json file the define these keys:

"AllowedHosts": "*",
  "PayPalConfig": {
    "CancelUrl": "https://localhost:44315/payment/cancelled OR Your Public Address",
    "ReturnUrl": "https://localhost:44315/payment/verify OR Your Public Address",
    "ClientID": "You Will GET THIS From PayPAL Account",
    "ClientSecretID": "You Will GET THIS From PayPAL Account",
    "IsSandBox": true
  }

Register the Paypalclient in your startup:

services.Configure<PayPalConfig>(options=>Configuration.GetSection("PayPalConfig").Bind(options));
services.AddSingleton<IPayPalService,PayPalService>();

And finally your payment controller can be like below:

public class PaymentController : Controller
    {
        private readonly IPayPalService payPalService;
        public PaymentController(IPayPalService payPalService)
        {
            this.payPalService = payPalService;
        }
        //create payment and redirect user to paypal
        public async Task<IActionResult> CreatePayment(string amount, string pid)
        {
            //pid is my parameter which i want to get it after the payment is done.
            var res = await payPalService.CreatePaymentOrderAsync(amount, customParameters: new Dictionary<string, string>() { { "pid", pid } });
            return Redirect(res.Links.FirstOrDefault(q => q.Rel.ToLower().Equals("approve")).Href);
        }
        public IActionResult cancelled()
        {
            return View();
        }
        //Return from paypal
        public async Task<IActionResult> Verify(string token = "", string PayerID = "", string pid = "")
        {
            var AuthorizedPayment = await payPalService.AuthorizePaymentOrderAsync(token);
            string AuthorizationID = AuthorizedPayment.PurchaseUnits[0].Payments.Authorizations[0].Id;
            var capture = await payPalService.CapturePaymentAsync(AuthorizationID);
       
            return View();
        }

        ///we can capture the payment and finalize it
        public async Task<JsonResult> Capture(string aid)
        {
            var FinalizePayment = await payPalService.CapturePaymentAsync(aid);
            string captureID = FinalizePayment.Id;
            return Json(captureID);
        }

        ///we can refund
        public async Task<IActionResult> Refund(string captureId, string amount, string unit)
        {
            var tt = await payPalService.CaptureRefundAsync(captureId, amount, unit);
            return Json(true);
        }
    }
