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.

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

Stores

List Stores

Get a paginated list of stores.

API Documentation

var options = new ClientListStoresOptions {
    PageSize = 10,
    ContinuationToken = "...",
};
var response = await fgaClient.ListStores(options);

// 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

Initialize a store.

API Documentation

var store = await fgaClient.CreateStore(new ClientCreateStoreRequest(){Name = "FGA Demo"})

// store.Id = "01FQH7V8BEG3GPQW93KTRFR8JB"

// store store.Id in database

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

// continue calling the API normally

Get Store

Get information about the current store.

API Documentation

Requires a client initialized with a storeId

var store = await fgaClient.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

Delete a store.

API Documentation

Requires a client initialized with a storeId

var store = await fgaClient.DeleteStore();

Authorization Models

Read Authorization Models

Read all authorization models in the store.

API Documentation

var options = new ClientReadAuthorizationModelsOptions {
    PageSize = 10,
    ContinuationToken = "...",
};
var response = await fgaClient.ReadAuthorizationModels(options);

// response.AuthorizationModels = [
// { Id: "01GXSA8YR785C4FYS3C0RTG7B1", SchemaVersion: "1.1", TypeDefinitions: [...] },
// { Id: "01GXSBM5PVYHCJNRNKXMB4QZTW", SchemaVersion: "1.1", TypeDefinitions: [...] }];

Write Authorization Model

Create a new 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.

You can use the OpenFGA Syntax Transformer to convert between the friendly DSL and the JSON authorization model.

var body = new ClientWriteAuthorizationModelRequest {
    SchemaVersion = "1.1",
    TypeDefinitions = new List<TypeDefinition> {
        new() {Type = "user", Relations = new Dictionary<string, Userset>()},
        new() {Type = "document",
            Relations = new Dictionary<string, Userset> {
                {"writer", new Userset {This = new object()}}, {
                    "viewer", new Userset {
                        Union = new Usersets {
                            Child = new List<Userset> {
                                new() {This = new object()},
                                new() {ComputedUserset = new ObjectRelation {Relation = "writer"}}
                            }
                        }
                    }
                }
            },
            Metadata = new Metadata {
                Relations = new Dictionary<string, RelationMetadata> {
                    {"writer", new RelationMetadata {
                        DirectlyRelatedUserTypes = new List<RelationReference> {
                            new() {Type = "user"}
                        }
                    }}, {"viewer", new RelationMetadata {
                        DirectlyRelatedUserTypes = new List<RelationReference> {
                            new() {Type = "user"}
                        }
                    }}
                }
            }
        }
    }
};

var response = await fgaClient.WriteAuthorizationModel(body);

// response.AuthorizationModelId = "01GXSA8YR785C4FYS3C0RTG7B1"

Read a Single Authorization Model

Read a particular authorization model.

API Documentation

var options = new ClientReadAuthorizationModelOptions {
    // You can rely on the model id set in the configuration or override it for this specific request
    AuthorizationModelId = "01GXSA8YR785C4FYS3C0RTG7B1",
};

var response = await fgaClient.ReadAuthorizationModel(options);

// response.AuthorizationModel.Id = "01GXSA8YR785C4FYS3C0RTG7B1"
// response.AuthorizationModel.SchemaVersion = "1.1"
// response.AuthorizationModel.TypeDefinitions = [{ "type": "document", "relations": { ... } }, { "type": "user", "relations": { ... }}]

Read the Latest Authorization Model

Reads the latest authorization model (note: this ignores the model id in configuration).

API Documentation

var response = await fgaClient.ReadLatestAuthorizationModel();

// response.AuthorizationModel.Id = "01GXSA8YR785C4FYS3C0RTG7B1"
// response.AuthorizationModel.SchemaVersion = "1.1"
// response.AuthorizationModel.TypeDefinitions = [{ "type": "document", "relations": { ... } }, { "type": "user", "relations": { ... }}]

Relationship Tuples

Read Relationship Tuple Changes (Watch)

Reads the list of historical relationship tuple writes and deletes.

API Documentation

var body = new ClientReadChangesRequest { Type = "document" };
var options = new ClientReadChangesOptions {
    PageSize = 10,
    ContinuationToken = "...",
};

var response = await fgaClient.ReadChanges(body, options);

// response.ContinuationToken = ...
// response.Changes = [
//   { TupleKey: { User, Relation, Object }, Operation: TupleOperation.WRITE, Timestamp: ... },
//   { TupleKey: { User, Relation, Object }, Operation: TupleOperation.DELETE, Timestamp: ... }
// ]

Read Relationship Tuples

Reads the relationship tuples stored in the database. It does not evaluate nor exclude invalid tuples according to the authorization model.

API Documentation

// Find if a relationship tuple stating that a certain user is a viewer of a certain document
var body = new ClientReadRequest() {
    User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
    Relation = "viewer",
    Object = "document:roadmap",
};

// Find all relationship tuples where a certain user has a relationship as any relation to a certain document
var body = new ClientReadRequest() {
    User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
    Object = "document:roadmap",
};

// Find all relationship tuples where a certain user is a viewer of any document
var body = new ClientReadRequest() {
    User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
    Relation = "viewer",
    Object = "document:",
};

// Find all relationship tuples where any user has a relationship as any relation with a particular document

var body = new ClientReadRequest() {
    Object = "document:roadmap",
};

// Read all stored relationship tuples
var body = new ClientReadRequest();

var options = new ClientReadOptions {
    PageSize = 10,
    ContinuationToken = "...",
};

var response = await fgaClient.Read(body, options);

// In all the above situations, the response will be of the form:
// response = { Tuples: [{ Key: { User, Relation, Object }, Timestamp }, ...]}

Write (Create and Delete) Relationship Tuples

Create and/or delete relationship tuples to update the system state.

API Documentation

Transaction mode (default)

By default, write runs in a transaction mode where any invalid operation (deleting a non-existing tuple, creating an existing tuple, one of the tuples was invalid) or a server error will fail the entire operation.

var body = new ClientWriteRequest() {
    Writes = new List<ClientTupleKey> {
        new() {
            User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
            Relation = "viewer",
            Object = "document:roadmap",
        },
        new() {
            User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
            Relation = "viewer",
            Object = "document:budget",
        }
    },
    Deletes = new List<ClientTupleKeyWithoutCondition> {
        new() {
            User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
            Relation = "writer",
            Object = "document:roadmap",
        }
    },
};
var options = new ClientWriteOptions {
    // You can rely on the model id set in the configuration or override it for this specific request
    AuthorizationModelId = "01GXSA8YR785C4FYS3C0RTG7B1",
};
var response = await fgaClient.Write(body, options);

Convenience WriteTuples and DeleteTuples methods are also available.

Non-transaction mode

The SDK will split the writes into separate requests and send them sequentially to avoid violating rate limits.

var body = new ClientWriteRequest() {
    Writes = new List<ClientTupleKey> {
        new() {
            User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
            Relation = "viewer",
            Object = "document:roadmap",
        },
        new() {
            User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
            Relation = "viewer",
            Object = "document:budget",
        }
    },
    Deletes = new List<ClientTupleKeyWithoutCondition> {
        new() {
            User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
            Relation = "writer",
            Object = "document:roadmap",
        }
    },
};
var options = new ClientWriteOptions {
    // You can rely on the model id set in the configuration or override it for this specific request
    AuthorizationModelId = "01GXSA8YR785C4FYS3C0RTG7B1",
    Transaction = new TransactionOptions() {
        Disable = true,
        MaxParallelRequests = 5, // Maximum number of requests to issue in parallel
        MaxPerChunk = 1, // Maximum number of requests to be sent in a transaction in a particular chunk
    }
};
var response = await fgaClient.Write(body, options);

Relationship Queries

Check

Check if a user has a particular relation with an object.

API Documentation

var options = new ClientCheckOptions {
    // You can rely on the model id set in the configuration or override it for this specific request
    AuthorizationModelId = "01GXSA8YR785C4FYS3C0RTG7B1",
};
var body = new ClientCheckRequest {
    User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
    Relation = "writer",
    Object = "document:roadmap"
};
var response = await fgaClient.Check(body, options);
// response.Allowed = true

Batch Check

Run a set of checks. Batch Check will return allowed: false if it encounters an error, and will return the error in the body. If 429s or 5xxs are encountered, the underlying check will retry up to 15 times before giving up.

var options = new ClientBatchCheckOptions {
    // You can rely on the model id set in the configuration or override it for this specific request
    AuthorizationModelId = "01GXSA8YR785C4FYS3C0RTG7B1",
    MaxParallelRequests = 5, // Max number of requests to issue in parallel, defaults to 10
};
var body = new List<ClientCheckRequest>(){
    new() {
        User = "user:81684243-9356-4421-8fbf-a4f8d36aa31b",
