Paypal v2 express checkout integration in .NET - paypal

Question

I am currently checking integration process of v2 express checkout and lot of documentation making confusion.
So far i am using checkout.js from paypal domain and using below code for order creation in client side as below
paypal.Button.render({
env: 'sandbox', // Or 'sandbox',
commit: true, // Show a 'Pay Now' button
style: {
color: 'gold',
shape: 'rect',
label: 'paypal',
size: 'medium',
tagline: false,
width: 150
},
payment: function (data, actions) {
/* Set up a url on your server to create the payment */
var CREATE_URL = '/paypal/createpaypalPayment';
/* Make a call to your server to set up the payment */
return paypal.request.post(CREATE_URL)
.then(function ({ result }) {
var test = JSON.parse(result);
return test.id;
});
},
onAuthorize: function (data, actions) {
/* Set up a url on your server to execute the payment */
var EXECUTE_URL = '/paypal/executepaypalPayment';
/* Set up the data you need to pass to your server */
var data = {
paymentID: data.paymentID,
payerID: data.payerID
};
return paypal.request.post(EXECUTE_URL, data)
.then(function (res) {
return null;
});
}
}, '#paypalcheckout');
});
Please find the server side code for create order.
[HttpPost]
public JsonResult createpaypalpayment()
{
var client = new WebClient();
string credentials = clientid + secretid;
client.Headers.Add("authorization", "Basic " + credentials);
client.Headers.Add("content-type", "application/json");
client.Headers.Add("accept-language", "en_US");
client.Headers.Add("accept", "application/json");
var body = #"{
""intent"": ""AUTHORIZE"",
""purchase_units"": [{
""amount"": {
""currency_code"": ""USD"",
""value"": ""100.00""
}
}]
}";
try
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
var response = client.UploadString("https://api.sandbox.paypal.com/v2/checkout/orders/", "POST", body);
return Json(new { result = response }, JsonRequestBehavior.AllowGet);
}
}
}
I referred below documentation
https://developer.paypal.com/docs/archive/orders-integration-guide/#integration-steps
I am struct with how to show order details after order creation and get approval from customer end ?
Can anyone provide suggestion for this.
Thanks in advance

Answer 1

checkout.js is deprecated and that documentation is archived, so my suggestion is that you follow the current documentation on developer.paypal.com
In your other question, links were provided to that documentation.
