oidc-exchange 0.2.0

Python bindings for oidc-exchange - OIDC token exchange service

oidc-exchange

Python binding for oidc-exchange — a Rust service that validates ID tokens from third-party OIDC providers (Google, Apple, …) and exchanges them for self-issued access and refresh tokens.

The service is embedded in-process as a native extension (built with PyO3 + maturin). Handle requests synchronously or with async, or mount the built-in ASGI/WSGI apps in FastAPI, Starlette, Flask, or Django.

Install

pip install oidc-exchange

Ships as an abi3 wheel — one wheel per platform works on Python 3.10+: manylinux_2_28 x86_64/aarch64, win_amd64, and macosx_11_0_arm64. An sdist is published alongside for other platforms (needs a Rust toolchain to build).

Usage

ASGI (FastAPI / Starlette)

from fastapi import FastAPI
from oidc_exchange import OidcExchange

oidc = OidcExchange(config="./config.toml")
app = FastAPI()
app.mount("/auth", oidc.asgi_app())

WSGI (Flask / Django)

from oidc_exchange import OidcExchange

oidc = OidcExchange(config_string="""
[server]
issuer = "https://auth.example.com"
…
""")
application = oidc.wsgi_app()

Direct request handling

resp = oidc.handle_request_sync({
    "method": "POST",
    "path": "/token",
    "headers": {"content-type": "application/json"},
    "body": b'{"grant_type": "authorization_code", "code": "…", "provider": "google"}',
})
# resp -> {"status": 200, "headers": {...}, "body": b"…"}

# or await the async variant (runs the blocking call in the default executor):
resp = await oidc.handle_request(request)

API

class OidcExchange:
    def __init__(self, *, config: str | None = None, config_string: str | None = None) -> None: ...
    def handle_request_sync(self, request: dict) -> dict: ...
    async def handle_request(self, request: dict) -> dict: ...
    def asgi_app(self) -> Any: ...   # mountable ASGI application
    def wsgi_app(self) -> Any: ...   # mountable WSGI application
    def shutdown(self) -> None: ...

A request dict is {"method", "path", "headers": dict[str, str], "body": bytes}; the response is {"status", "headers": dict[str, str], "body": bytes}. The full service is exposed — /token, /revoke, /keys, /.well-known/openid-configuration, /health, and the internal admin API.

Framework examples

See the main repo's Python examples: FastAPI, Flask, Django.

Configuration

TOML config — providers, token TTLs, registration policy, key management, and storage. See the configuration guide.
