Code in

net/http (Go)

Coming soon. github.com/Atheron-ATON-Network/atheron-sdk-go is not published on Go modules yet, so the install line on this page does not work until it is. Until then, everything works over plain HTTP: pick cURL in any code block, or start from Endpoints.

The core package signs people in on net/http with nothing else installed: auth.Handler() for the routes, auth.RequireUser for the pages, and the session sealed in a cookie.

Set ATHERON_CLIENT_ID, ATHERON_CLIENT_SECRET, ATHERON_REDIRECT_URI (the callback address you registered, such as https://your.app/auth/callback) and ATHERON_SESSION_SECRET (32 random characters or more, which seal the session cookie) on your server. The routes are /auth/sign-in, /auth/callback, /auth/sign-out (a POST from your own site) and /auth/session.

Mount the routes

This example is not written in cURL yet. Showing Next.js.

// app/auth/[...atheron]/route.ts: every Sign in with Atheron route in one file.
// Set ATHERON_CLIENT_ID, ATHERON_CLIENT_SECRET, ATHERON_SECRET and
// ATHERON_REDIRECT_URI=https://your.app/auth/callback (the address you registered).
import { Atheron } from "@aton-network/nextjs";

const atheron = Atheron();

export const { GET, POST } = atheron.handlers;

Protect a page

This example is not written in cURL yet. Showing Next.js.

// proxy.ts (middleware.ts before Next 16): anybody not signed in goes to Atheron first, then back.
import { Atheron } from "@aton-network/nextjs";

const atheron = Atheron({ protect: ["/account", "/settings"] });

export async function proxy(request: Request): Promise<Response | undefined> {
  return atheron.proxy(request);
}

// In a server component, read the person with: await atheron.user(await cookies())

Webhooks

The session is an AES-GCM sealed, HttpOnly, SameSite=Lax cookie that the browser can neither read nor change. To keep sessions on the server instead, set Config.Store to atheron.NewMemoryStore(true) for one server, or to a Store of your own over Redis or a database.

PKCE, state and nonce are checked on every sign-in, the flow is spent on use and lasts ten minutes, a return address is always a path on your site, signing out revokes the refresh token at Atheron, and a sign-out from another site is refused.

This example is not written in cURL yet. Showing TypeScript.

// Check that a webhook came from Atheron before you act on it. Pass the raw body, exactly as received.
import { verifyWebhook, type WebhookEvent } from "@aton-network/sdk";

export async function handleWebhook(request: Request): Promise<Response> {
  const raw = await request.text();
  const ok = await verifyWebhook(request.headers.get("atheron-signature"), raw, process.env.ATHERON_WEBHOOK_SECRET!);
  if (!ok) return new Response("bad signature", { status: 400 });
  const event = JSON.parse(raw) as WebhookEvent;
  if (event.type === "consent.revoked") {
    // Delete the refresh token you hold for event.data.sub, and stop using what you read.
  }
  return new Response(null, { status: 204 });
}
