this package provide ChargilyEpayClient client, to create payment request use:

using Chargily.Epay;

var client = ChargilyEpay.CreateClient("[API_KEY]");

var payment = new EpayPaymentRequest()
{
    InvoiceNumber = "[INVOICE_NUMBER]",

    ExtraInfo = "Product Purchase"
};

var response = await client.CreatePayment(payment);

this applies to:

  • ASP.NET Core WebAPI
  • ASP.NET Core Minimal WebAPI
  • Blazor Server
  • Blazor WASM
  • ASP.NET Core MVC
using Chargily.Epay;
using Microsoft.AspNetCore.Mvc;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddChargilyEpayGateway("[API_KEY]");

var app = builder.Build();

app.MapPost("/invoice",
    async ([FromBody] EpayPaymentRequest request,
        [FromServices] IChargilyEpayClient<EpayPaymentResponse, EpayPaymentRequest> chargilyClient) =>
    {
        return await chargilyClient.CreatePayment(request);
    });

app.Run();

​
Request:

{
    "invoice_number" : "321616",
    "client" : "Ahmed",
    "client_email" : "rainxh11@gmail.com",
    "amount" : 1500,
    "discount" : 5.0,
    "mode" : "EDAHABIA",
    "back_url" : "https://example.com/",
    "webhook_url" : "https://shop.com/purchase",
    "comment" : "Product Purchase"
}

​
Response:

{
    "httpStatusCode": 201,
    "responseMessage": {
        "Message": "Success"
    },
    "isSuccessful": true,
    "isRequestValid": true,
    "body": {
        "checkout_url": "https://epay.chargily.com.dz/checkout/d00c1e652200798bbc35f688b2910fa9bc6c4c30d38b51e3f4142e407fa7c141"
    },
    "createdOn": "2022-05-06T03:55:49.6527862+01:00"
}

​
WebHook Validation:

using Chargily.Epay;
using Microsoft.AspNetCore.Mvc;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddChargilyWebHookValidator("[APP_SECRET]");

var app = builder.Build();
app.MapPost("/webhook-validator", ([FromServices] IWebHookValidator validator, HttpRequest request) =>
{
    var signature = request.Headers["Signature"].First();
    var validation = validator.Validate(signature, request.Body);

    return validation;
});

app.Run();

​
Configuration:

API_KEY & APP_SECRET can be added directly in code or from appsettings.json configuration file

builder.Services.AddChargilyWebHookValidator("[APP_SECRET]");
builder.Services.AddChargilyEpayGateway("[API_KEY]");

// OR

builder.Services.AddChargilyWebHookValidator(builder.Configuration["CHARGILY_APP_SECRET"]);
builder.Services.AddChargilyEpayGateway(builder.Configuration["CHARGILY_API_KEY"]);

// OR
// Same as previous but it will be loaded automatically from appsettings.json
builder.Services.AddChargilyWebHookValidator());
builder.Services.AddChargilyEpayGateway();

appsettings.json file:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "CHARGILY_APP_SECRET": "[APP_SECRET]", // <-- APP SECRET
  "CHARGILY_API_KEY": "[API_KEY]" // <-- API KEY
}

​
ASP.NET Core Middleware

This package provide WebHookValidatorMiddleware ASP.NET Core Middleware, when registered every POST request that have a Signature Http Header will be validated automatically. How to register the Middleware:

using Chargily.Epay;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddChargilyEpayGateway("[API_KEY]");

builder.Services
    .AddChargilyValidatorMiddleware("[APP_SECRET]"); // WebHookValidatorMiddleware have to be registered

var app = builder.Build();

app.UseChargilyValidatorMiddleware();

app.Run();

​
Usage with .NET MAUI

using Microsoft.Maui;
using Microsoft.Maui.Hosting;
using Microsoft.Maui.Controls.Compatibility;
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Chargily.Epay;

namespace MyApp
{
  public static class MauiProgram
  {
    public static MauiApp CreateMauiApp()
    {
      var builder = MauiApp.CreateBuilder();
      builder.UseMauiApp<App>();
      builder.Services.AddChargilyEpayGateway("[API_KEY]");
      return builder.Build();
    }
  }
}

then you can add in ViewModels:

public class MainViewModel : ViewModelBase  
{  
    private ChargilyEpayClient _chargilyClient;  
    private IWebHookValidator _webhookValidator;

    public MainViewModel(ChargilyEpayClient chargilyClient)  
    {  
        _chargilyClient = chargilyClient;  
    }  
    // With Validator
    public MainViewModel(ChargilyEpayClient chargilyClient, IWebHookValidator webhookValidator)  
    {  
        _chargilyClient = chargilyClient;  
        _webhookValidator = webhookValidator;
    }  
}

​
Note when using .NET MAUI / Xamarin:

storing sensitive APP_SECRET in a frontend app is not a recommended approach, you’d be better off calling a backend api to handle payment, but it’s doable. if you decide to use it in the frontend, consider storing APP_SECRET with Akavache BlobCache.Secure

​
This package is using Microsoft.Extensions.DependencyInjection dependancy injection, so it can be used with application or framework using it.
