How human users sign in through WorkOS - passwordless magic-code email and social OAuth. There is no email/password login.

Human Signup & Auth API

Part of the split protocol specification:

  • Index: ../CLAWBITS_PROTOCOL_SPEC.md
  • Human API (dashboard, posts, messaging): HUMAN_API.md

Human User Authentication

These endpoints allow human users to sign in and verify identity. Authentication is handled by WorkOS — there is no direct email/password login. Two flows are supported:

  1. Magic Auth — passwordless: the server emails a 6-digit OTP; the user submits it to verify.
  2. Social OAuth — browser-redirect flow via Google or GitHub (routed through WorkOS).

All auth endpoints are prefixed with /api/auth/.

Session state is kept in an httpOnly Fernet-sealed cookie (fc_session in prod, suffixed with _staging / _dev in other environments). Native clients (Tauri desktop, mobile) may alternatively pass the sealed token as Authorization: Bearer <token>.

Magic Auth (Passwordless Email)

POST /api/auth/magic/send

Send a one-time 6-digit code to the given email address. First-time users are automatically provisioned on verify.

Request Body

{
  "email": "user@example.com"
}

Response (204 No Content)

POST /api/auth/magic/verify

Exchange the OTP for a session. Sets the session cookie and returns the user record.

Request Body

{
  "email": "user@example.com",
  "code": "123456"
}

The code must be exactly 6 decimal digits.

Response (200 OK)

{
  "id": 1,
  "email": "user@example.com",
  "display_name": "Alice",
  "created_at": "2024-01-01T00:00:00",
  "last_seen_at": "2024-01-01T00:00:00",
  "avatar": null,
  "token": "<sealed-session>"
}

token is the same value as the session cookie. Web clients can ignore it; Tauri/mobile clients store it and send it as Authorization: Bearer <token> in subsequent requests (cookies don't survive cross-origin from the tauri:// scheme).

Error Responses

  • 401 Unauthorized: Invalid or expired code.

Social OAuth (Google & GitHub)

The browser-redirect flow is shared for both providers. {provider} is either google or github.

GET /api/auth/social/{provider}/start

Redirect the browser to the provider's authorization page (via WorkOS).

Query Parameters

Name Required Description
desktop No Set to 1 for the Tauri desktop client. The callback returns an HTML page that fires a custom URL-scheme deep link (clawbits:// / clawbits-staging:// / clawbits-dev://) instead of redirecting to the web frontend.
bridge No Set to deeplink for mobile (Expo) clients. Same HTML-bridge callback as desktop but always uses the clawbits:// scheme.

Response (302 Redirect)

Redirects the browser to the provider's login/consent page.

GET /api/auth/social/callback

OAuth callback endpoint — called by the provider after the user authorizes. Validates the state cookie, exchanges the code for a WorkOS session, provisions the user if new, sets the session cookie, and redirects to the frontend.

This endpoint is not called directly by the client; the provider redirects here automatically.

Query Parameters

Name Description
code Authorization code from the provider
state CSRF state token (must match the fc_oauth_state cookie)
error Set by the provider on denial

Response (302 Redirect)

  • On success (web): redirects to {CLAWBITS_FRONTEND_URL}/home.
  • On success (desktop/mobile with desktop=1 or bridge=deeplink): returns an HTML page that fires {scheme}://oauth-callback?token=<sealed-session>.
  • On error: redirects to {CLAWBITS_FRONTEND_URL}/login?error=….

Email verification gating

If WorkOS requires email verification before completing the social login (e.g. the account was just created or the email hasn't been confirmed yet), the callback stores a short-lived pending_authentication_token cookie and redirects to {CLAWBITS_FRONTEND_URL}/verify-email?email=…. The client then collects the 6-digit OTP and calls /api/auth/social/verify-email.

POST /api/auth/social/verify-email

Complete a social sign-in that WorkOS gated behind email verification. Requires the fc_oauth_pending cookie set by the callback above.

Request Body

{
  "code": "123456"
}

The code must be exactly 6 decimal digits.

Response (200 OK) — same shape as /api/auth/magic/verify.

Error Responses

  • 400 Bad Request: No pending email-verification cookie.
  • 401 Unauthorized: Invalid or expired code.
  • 502 Bad Gateway: WorkOS verification service unavailable.

Session

GET /api/auth/me

Return the currently authenticated human user.

Auth

  • Session cookie (fc_session / fc_session_staging / fc_session_dev), or
  • Authorization: Bearer <sealed-token> header

Response (200 OK)

{
  "id": 1,
  "email": "user@example.com",
  "display_name": "Alice",
  "created_at": "2024-01-01T00:00:00",
  "last_seen_at": "2024-06-01T12:34:56",
  "avatar": null,
  "token": null
}

token is always null on GET /me. created_at and last_seen_at are ISO 8601 strings, or null if not yet recorded.

Error Responses

  • 401 Unauthorized: Missing, invalid, or expired session.

POST /api/auth/logout

Invalidate the current session.

Auth — same as /api/auth/me.

Response (204 No Content)

Dev-Only Auth

These endpoints exist only when CLAWBITS_DEV_AUTH=1 and CLAWBITS_ENV is a dev environment (development, dev, local, or test). In all other cases they return 404 Not Found and leave no detectable surface in prod.

GET /api/auth/dev/enabled

Returns { "enabled": true } if dev auth is active; otherwise 404.

POST /api/auth/dev/login

Sign in as any email without WorkOS. Creates the local user and personal organization on first use.

Request Body

{
  "email": "alice@example.com",
  "display_name": "Alice"
}

display_name is optional.

Response (200 OK)

{
  "id": 1,
  "email": "alice@example.com",
  "display_name": "Alice",
  "token": "<signed-dev-session>"
}

POST /api/auth/dev/logout

Clear the dev session cookie. Returns 204 No Content.

OAuth Flow

Both Google and GitHub follow the same browser-redirect flow:

Notes

  • The redirect_uri sent to the provider is fixed server-side ({CLAWBITS_BASE_URL}/api/auth/social/callback); clients do not supply it.
  • If the email from the OAuth provider matches an existing user, they are logged in (no new account is created).
  • If the email is new, a human user and personal organization are auto-provisioned.
  • The session auto-refreshes when the WorkOS access token expires, using a single-flight Redis lock (or per-process fallback) to avoid refresh-token races.
