I want to add payment gateway from square.com in my c# mvc project. I already tried lots of things from google but unable to find proper solution.

Here is my controller code I already tried

public ActionResult Squre()
{
_transactionApi = new TransactionApi();

var client = new RestSharp.RestClient();
var request = new RestSharp.RestRequest("https://connect.squareup.com/v1/me/payments", RestSharp.Method.GET);
request.RequestFormat = RestSharp.DataFormat.Json;
request.AddHeader("Authorization", "Bearer sq0atp-zHuWWPD4ds9J6YoVlEoYZg");
setHeaders(request);
var Response = client.Execute(request);

HttpWebResponse response = null;
string responseMessage = null;
response = (HttpWebResponse)request.GetResponse();

if (response.StatusCode == HttpStatusCode.OK)
{
using (Stream stream = response.GetResponseStream())
{
using (StreamReader reader = new StreamReader(stream))
{
responseMessage = reader.ReadToEnd();
}
}
}

return View();
}

namespaces i have used mentioned below here

using System.Runtime.Serialization.Json;
using Square.Connect.Api;

The links provide the details, including the code sample.   If you are working in C#, follow the instructions on https://github.com/square/connect-api-examples/tree/master/connect-examples/v2/csharp_payment and look at the downloaded files.  (You can find the download link on https://github.com/square/connect-api-examples, and you would only use the files in the folder corresponding to the example you are following, in csharp_payment)

Hi Kathy

I am trying to use the latest v2 and the sample code that references Money.ToCurrencyEnum doesn't seem to exist anymore. Do you know how to get around this?

Money amount = NewMoney(100, "USD");

public static Money NewMoney(int amount, string currency)
{
return new Money(amount, Money.ToCurrencyEnum(currency));
}

the example lacks an important element. here is the comment as it exists in the example

// Monetary amounts are specified in the smallest unit of the applicable currency.
// This amount is in cents. It's also hard-coded for $1.00,
// which isn't very useful.

I have to agree it isn't very useful and it's Square's own example..???

I have submitted 2 support request with them and have received no reply...

the question, for me, is how do I replace the hardcoded 100 with the total charge value form the form? in MVC5 C#

the code is in ProcessPament.cshtml.cs in the example.

Money amount = new Money(100, Money.CurrencyEnum.USD);

ANY help would be greatly appreciated TIA

Yours in frustration

did you even look at the source code?

The the important data is collected in the sample javascript routine onGetCardNonce(). the nonce value is all that's passed to the mvc action, the square javascript calls square server and passes all the the information collected from your supplied onGetCardNonce(). presumably your UI would have a form field to identity the whats purchased, the unit count, the server should calc the amount, as if it was a post back value the user could hack it. if you must post back the amount, it should be encrypted.

the security feature of square, is that the credit card info does not go to your site, only the nonce (transaction identifier is sent to your site). your site uses this and the amount to do a charge.
