Authenticate into Fused - Fused

Direct OAuth 2.0 client for Fused’s own authorization server. Download the fixed fused-auth package:

fused-cli sdk auth-client --language ts      # TypeScript, npm package "fused-auth"
fused-cli sdk auth-client --language python  # Python, import "fused.fused_auth"

Register a client under Access → OAuth Clients first. Confidential clients return a one-time client_secret; public clients use PKCE with no secret. The redirect URI must match the one you registered.

import { FusedAuthClient } from "fused-auth";

const client = new FusedAuthClient({
  issuer: "https://engine.example.com",
  clientId: "foc_...",
  clientSecret: "fos_...", // omit for public clients
  redirectUri: "https://app.example.com/oauth/callback",
});

// 1. Start the flow and send the user's browser to `url`.
const { url, state, codeVerifier } = await client.authorizeUrl({
  scopes: ["service.consume"],
});

// 2. On the callback, exchange the code.
const tokens = await client.exchangeCode(code, codeVerifier);

// 3. Refresh and revoke as needed.
const refreshed = await client.refresh(tokens.refresh_token!);
await client.revoke(refreshed.access_token);

from fused.fused_auth import FusedAuthClient, FusedAuthConfig

client = FusedAuthClient(FusedAuthConfig(
    issuer="https://engine.example.com",
    client_id="foc_...",
    client_secret="fos_...",  # omit for public clients
    redirect_uri="https://app.example.com/oauth/callback",
))

# 1. Start the flow and send the user's browser to `req.url`.
req = client.authorize_url(scopes=["service.consume"])

# 2. On the callback, exchange the code.
tokens = client.exchange_code(code, req.code_verifier)

# 3. Refresh and revoke as needed.
refreshed = client.refresh(tokens.refresh_token)
client.revoke(refreshed.access_token)
