authzed 0.14.0

Client library for SpiceDB.

Authzed Python Client

This repository houses the Python client library for Authzed.

Authzed is a database and service that stores, computes, and validates your application's permissions.

Developers create a schema that models their permissions requirements and use a client library, such as this one, to apply the schema to the database, insert data into the database, and query the data to efficiently check permissions in their applications.

Supported client API versions:

• v1

You can find more info on each API on the Authzed API reference documentation. Additionally, Protobuf API documentation can be found on the Buf Registry Authzed API repository.

See CONTRIBUTING.md for instructions on how to contribute and perform common tasks like building the project and running tests.

Getting Started

We highly recommend following the Protecting Your First App guide to learn the latest best practice to integrate an application with Authzed.

If you're interested in examples of a specific version of the API, they can be found in their respective folders in the examples directory.

Basic Usage

Installation

This project is packaged as the wheel authzed on the Python Package Index.

If you are using pip, the command to install the library is:

pip install authzed

Initializing a client

With the exception of gRPC utility functions found in grpcutil, everything required to connect and make API calls is located in a module respective to API version.

In order to successfully connect, you will have to provide a Bearer Token with your own API Token from the Authzed dashboard in place of t_your_token_here_1234567deadbeef in the following example:

from authzed.api.v1 import Client
from grpcutil import bearer_token_credentials


client = Client(
    "grpc.authzed.com:443",
    bearer_token_credentials("t_your_token_here_1234567deadbeef"),
)

Performing an API call

from authzed.api.v1 import (
    CheckPermissionRequest,
    CheckPermissionResponse,
    ObjectReference,
    SubjectReference,
)


post_one = ObjectReference(object_type="blog/post", object_id="1")
emilia = SubjectReference(object=ObjectReference(
    object_type="blog/user",
    object_id="emilia",
))

# Is Emilia in the set of users that can read post #1?
resp = client.CheckPermission(CheckPermissionRequest(
    resource=post_one,
    permission="reader",
    subject=emilia,
))
assert resp.permissionship == CheckPermissionResponse.PERMISSIONSHIP_HAS_PERMISSION
