About

OpenFGA is an open source Fine-Grained Authorization solution inspired by Google's Zanzibar paper. It was created by the FGA team at Auth0 based on Auth0 Fine-Grained Authorization (FGA), available under a permissive license (Apache-2) and welcomes community contributions.

OpenFGA is designed to make it easy for application builders to model their permission layer, and to add and integrate fine-grained authorization into their applications. OpenFGA’s design is optimized for reliability and low latency at a high scale.

Installation

The OpenFGA .NET SDK is available on NuGet.

You can install it using:

• The dotnet CLI

dotnet add package OpenFga.Sdk

• The Package Manager Console inside Visual Studio:

Install-Package OpenFga.Sdk

• Visual Studio, Visual Studio for Mac and IntelliJ Rider

Search for and install OpenFga.Sdk in each of their respective package manager UIs.

Getting Started

Initializing the API Client

Without an API Token

using OpenFga.Sdk.Api;
using OpenFga.Sdk.Client;
using OpenFga.Sdk.Configuration;
using OpenFga.Sdk.Model;

namespace Example {
    public class Example {
        public static void Main() {
            try {
                var configuration = new Configuration() {
                    ApiScheme = Environment.GetEnvironmentVariable("OPENFGA_API_SCHEME"), // optional, defaults to "https"
                    ApiHost = Environment.GetEnvironmentVariable("OPENFGA_API_HOST"), // required, define without the scheme (e.g. api.fga.example instead of https://api.fga.example)
                    StoreId = Environment.GetEnvironmentVariable("OPENFGA_STORE_ID"), // not needed when calling `CreateStore` or `ListStores`
                };

Get your Store ID

You need your store id to call the OpenFGA API (unless it is to call the CreateStore or ListStores methods).

If your server is configured with authentication enabled, you also need to have your credentials ready.

Calling the API

List Stores

API Documentation

var configuration = new Configuration() {
    ApiScheme = Environment.GetEnvironmentVariable("OPENFGA_API_SCHEME"),
    ApiHost = Environment.GetEnvironmentVariable("OPENFGA_API_HOST"),
};
var openFgaApi = new OpenFgaApi(configuration);
var response = await openFgaApi.ListStores();

// stores = [{ "id": "01FQH7V8BEG3GPQW93KTRFR8JB", "name": "FGA Demo Store", "created_at": "2022-01-01T00:00:00.000Z", "updated_at": "2022-01-01T00:00:00.000Z" }]

Create Store

API Documentation

var configuration = new Configuration() {
    ApiScheme = Environment.GetEnvironmentVariable("OPENFGA_API_SCHEME"),
    ApiHost = Environment.GetEnvironmentVariable("OPENFGA_API_HOST"),
};
var openFgaApi = new OpenFgaApi(configuration);
var store = await openFgaApi.CreateStore(new CreateStoreRequest(){Name = "FGA Demo"})

// store.Id = "01FQH7V8BEG3GPQW93KTRFR8JB"

// store store.Id in database

// update the storeId of the current instance
openFgaApi.StoreId = storeId;

// continue calling the API normally

Get Store

API Documentation

Requires a client initialized with a storeId

var configuration = new Configuration() {
    ApiScheme = Environment.GetEnvironmentVariable("OPENFGA_API_SCHEME"),
    ApiHost = Environment.GetEnvironmentVariable("OPENFGA_API_HOST"),
    StoreId = Environment.GetEnvironmentVariable("OPENFGA_STORE_ID"),
};
var openFgaApi = new OpenFgaApi(configuration);
var store = await openFgaApi.GetStore();

// store = { "id": "01FQH7V8BEG3GPQW93KTRFR8JB", "name": "FGA Demo Store", "created_at": "2022-01-01T00:00:00.000Z", "updated_at": "2022-01-01T00:00:00.000Z" }

Delete Store

API Documentation

Requires a client initialized with a storeId

var store = await openFgaApi.DeleteStore();

Write Authorization Model

API Documentation

Note: To learn how to build your authorization model, check the Docs at https://openfga.dev/docs.

Learn more about the OpenFGA configuration language.

{
    {"writer", new Userset(_this: new object())},
    {
        "viewer",
        new Userset(union: new Usersets(new List<Userset>()
            {new(new object(), new ObjectRelation("", "writer"))}))
    }
};
var userRelations = new Dictionary<string, Userset>()

Read a Single Authorization Model

API Documentation

string authorizationModelId = "1uHxCSuTP0VKPYSnkq1pbb1jeZw"; // Assuming `1uHxCSuTP0VKPYSnkq1pbb1jeZw` is an id of an existing model
var response = await openFgaApi.ReadAuthorizationModel(authorizationModelId);

// response.AuthorizationModel.Id = "1uHxCSuTP0VKPYSnkq1pbb1jeZw"
// response.AuthorizationModel.TypeDefinitions = [{ "type": "document", "relations": { ... } }, { "type": "user", "relations": { ... }}]

    _object: "document:roadmap",
    user: "user:81684243-9356-4421-8fbf-a4f8d36aa31b"));

    _object: "document:",
    relation: "viewer",
    user: "user:81684243-9356-4421-8fbf-a4f8d36aa31b"));

// Find all relationship tuples where any user has a relationship as any relation with a particular document
var body = new ReadRequest(new TupleKey(
    _object: "document:roadmap"));

// Read all stored relationship tuples
body := ReadRequest()

var response = await openFgaApi.Read(body);

// In all the above situations, the response will be of the form:
// response = {"tuples":[{"key":{"user":"...","relation":"...","object":"..."},"timestamp":"..."}]}
