Paypal.net

Paypal.net is a wrapper library for Paypal subscription API.

Usage

Configure PayPal's API endpoint plus API key and secret. You can find these settings by creating an application in Paypal's developer dashboard.

// appsettings.json
"Paypal": {
    "ApiBaseUrl": "https://api-m.sandbox.paypal.com/",
    "ClientId": "your-client-id-here",
    "Secret": "your-secret-here"
}

Register library types by calling AddPaypalApi on IServiceCollection.

// Startup.cs
using Paypal.Net.Sdk.DependencyInjection;
// ...

public void ConfigureServices(IServiceCollection services) 
{
   // ...     
   services.AddPaypalApi();
}

Inject an instance of the proper API class whenever you need it.

using Paypal.Net.Sdk.Api;
// ...

// Inject the catalog API class
public IndexModel(CatalogProductApi catalogProductApi) 
{
    _catalogProductApi = catalogProductApi;
}

// Use the catalog API object to get a list of products
public async Task OnGet() 
{
    Definitions.ProductListResponse products = await _catalogProductApi.ListProductsAsync();
}

Why

Paypal's official SDK is not being maintained anymore (Home · paypal/PayPal-NET-SDK Wiki (github.com)). On top of that this SDK does not provide access to subscription API which allows merchants to create a recurring subscription for customers. This library is aiming to provide an un-opinionated wrapper for Paypal API that plays nicely with .net core dependency injection and configuration framework.

Todo

• Update type registration extensions to provide more flexibility for configuration using builder pattern.
• Add a configuration class and inject in all classes instead of directly accessing IConfiguration.
• Improve code coverage
• Add an example asp.net project
• Create a nuget package and publish
• Improve unit testability by introducing interfaces for API classes
• Update this readme with more examples and list of API classes
• Add webhook examples
