C# Paypal REST API-返回url无法使用ASP.NET核心

我正在ASP.NET内核中尝试使用Paypal REST API进行支付处理。我正在成功创建付款并获得批准链接。我使用此链接将我的用户重定向到Paypal以获得批准。问题是支付审批Paypal未重定向回返回\u url

}

批准后就留在那里

我的返回url代码

 [HttpGet]
    [Route("ExecutepaypalPayment")]
    public IActionResult ExecutepaypalPayment(string paymentID,string payerID)
    {
        string AuthToken = GetAuthToken();
        var client = new RestClient("https://api-m.sandbox.paypal.com/v1/payments/payment/"+paymentID+ "/execute");
        client.Timeout = -1;
        var requestNew = new RestRequest(Method.POST);
        requestNew.AddHeader("Content-Type", "application/json");
        requestNew.AddHeader("authorization", "Bearer " + AuthToken);
        string param = "{payer_id\":" +payerID+"\"}";
        requestNew.AddParameter("application/json", param, ParameterType.RequestBody);
        IRestResponse responseNew = client.Execute(requestNew);
        return Redirect("https://app.zoomtalktext.com/buy-credits/credits/addcredit");
    }
