C# SDK allows you to accept payment with Visa/MasterCard cards on your website.

Lates version of C# SDK you can always find in our public repository:

Step by step implementation case¶

You will find all code examples by link

create order and obtain payment token:

for this step you need class Token

if you are planing to use recurring payments in future, add parameter recurring = 'y' in request:

Config.ContentType = "json";
int amount = Convert.ToInt32(Request.Form["amount"].Substring(0,
    Request.Form["amount"].IndexOf('.') > 0
        ? Request.Form["amount"].IndexOf('.')
        : Request.Form["amount"].Length));
var req = new TokenRequest
{
    order_id = Request.Form["order_id"],
    recurring = "y",
    amount = amount * 100,
    order_desc = "Order description",
    currency = "GEL"
};
DoRequest(req);

in response you will receive payment token in parameter resp.token:

    private void DoRequest(TokenRequest req)
    {
        var resp = new Token().Post(req);
        if (resp.Error != null)
        {
            DataError = resp.Error.ErrorMessage;
            Data = resp.Error.RequestId;
        }
        else
        {
            DataUri = resp.token;
        }
    }

send payment token from resp.token to frontend.

You can choose 2 solutions for web payment form implementation on frontend: Embedded iframe or JavaScript native form both for cards and Apple/Google Pay

For JavaScript native frontend form pass payment token to JavaScript payment form in dictionary

    {
     "payment_system":"card",
     "token": `resp.token`,
     "card_number":"16/19-digits number",
     "expiry_date":"Supported formats: MM/YY, MM/YYYY, MMYY, MMYYYY",
     "cvv2":"3-digits number"
     }

For Embedded IFrame form pass payment token to payment form in Options object (see example)

var Options = {
  options: {
    methods: ['card'],
    methods_disabled: [],
    card_icons: ['mastercard', 'visa', 'maestro'],
    active_tab: 'card',
    fields: false,
    title: 'Demo checkout',
    link: 'https://shop.com',
    full_screen: true,
    button: true,
    email: true
  },
  params: {
    token: `resp.token`
  }
}
checkout("#checkout-container", Options);

Solution for mobile application you can choose depending on programming language framework you application is developed:

Apple Pay
Google Pay
