What is Open Payments?

Open Payments is an open API standard that can be implemented by account servicing entities (e.g. banks, digital wallet providers, and mobile money providers) to facilitate interoperability in the setup and completion of payments for different use cases including:

• Web Monetization
• Tipping/Donations (low value/low friction)
• eCommerce checkout
• P2P transfers
• Subscriptions
• Invoice Payments

The Open Payments APIs are a collection of three sub-systems:

• A wallet address server which exposes public information about Open Payments-enabled accounts called "wallet addresses"
• A resource server which exposes APIs for performing functions against the underlying accounts
• A authorisation server which exposes APIs compliant with the GNAP standard for getting grants to access the resource server APIs

This repository contains contains a .NET Open Payments SDK to make requests via the Open Payments API.

Local Development Environment

This repository contains a Git submodule, which contains the Open Payments OpenAPI specifications. After cloning, make sure to initialize and update it:

git submodule update --init

Alternatively, clone the repository with submodules in one step:

git clone --recurse-submodules git@github.com:interledger/open-payments-node.git

Prerequisites

• NVM
• .NET 9.0

Environment Setup

npm install -g swagger-cli && \
dotnet tool install --global NSwag.ConsoleCore

Now generate models from the OpenAPI specs. You can generate all of them by running the command below:

make models

However, you can generate them one by one (please check the Makefile for all supported commands).

🔧 Running the tests

dotnet test

🎈 Usage

To use in your project, just add the package using the command line

dotnet add package Interledger.OpenPayments

Then add it to your project code

// Import dependencies
using Microsoft.Extensions.DependencyInjection;
using OpenPayments.Sdk.Clients;
using OpenPayments.Sdk.Extensions;
using OpenPayments.Sdk.HttpSignatureUtils;

// Initialize client
var client = new ServiceCollection()
    .UseOpenPayments(opts =>
    {
        opts.UseAuthenticatedClient = true;
        opts.KeyId = CLIENT_ID;
        opts.PrivateKey = KeyUtils.LoadPem(CLIENT_SECRET);
        opts.ClientUrl = new Uri(CLIENT_WALLET_ADDRESS);
    })
    .BuildServiceProvider()
    .GetRequiredService<IAuthenticatedClient>();
