## Summary Implements [core-team-issues#2473](https://github.com/twentyhq/core-team-issues/issues/2473): serve HTTP-triggered logic functions from a dedicated, **cookieless** public domain (`{workspaceSubdomain}.withtwenty.com`) instead of the same-site `/s/` route, so functions can safely return **arbitrary headers** — custom headers, `Permissions-Policy` (camera/mic/geolocation), `Cross-Origin-Opener-Policy: same-origin`, `Cross-Origin-Embedder-Policy: require-corp`, `Set-Cookie`, etc. The `/s/` route stays the strict, same-site path it is today. **Self-hosting is unchanged** — everything new is gated on `PUBLIC_DOMAIN_URL` being set. ### Why Today user-authored function responses are served same-site with the Twenty app, so the response-header allow-list is restricted to 5 safe headers and request headers are limited to a per-function allow-list. Serving from an origin that shares nothing with `*.twenty.com` removes that constraint safely — the same "user content domain" pattern as GitHub (`*.githubusercontent.com`) and CodeSandbox (`*.csb.app`). ## What's in here **Routing** - The **root-path → `/s` rewrite happens at the nginx ingress**, not in app code. The existing `api-ingress.yaml` already rewrites root paths onto `/s` (host-agnostically) when the edge sets `X-Twenty-Public-Domain: true`, so `*.withtwenty.com` and registered custom public domains are handled by the same mechanism. (An earlier in-app middleware was removed as a redundant, wrong-layer duplicate.) - `WorkspaceDomainsService.resolveWorkspaceAndPublicDomain` recognizes `*.` subdomains, resolves the workspace by subdomain, and returns `isIsolatedOrigin`. Explicitly registered public-domain rows still take precedence and keep their application scoping. The ingress preserves the `Host` header, so this resolution still fires. **Headers (server)** - Isolated origin → all response headers pass through and all request headers are forwarded. Same-site `/s/` keeps the strict allow-lists. (Global CORS already handles preflight/ACAO.) **`/s/` deprecation for new routes (cloud only)** - New `LOGIC_FUNCTION_LEGACY_ROUTE_CUTOFF` config var (ISO date, optional). When `PUBLIC_DOMAIN_URL` is set, functions created on/after the cutoff return **410 Gone** on `/s/` with the new URL. Existing routes and self-hosted instances are untouched. **Frontend education** - `publicFunctionDomain` added to `ClientConfig` (from `PUBLIC_DOMAIN_URL`). - The logic-function **Live URL** now resolves to `https://{workspaceSubdomain}.{publicFunctionDomain}{path}` on cloud, falling back to `/s/` for self-hosting. - Front components call their functions through the SDK (`RestApiClient`), which now targets the isolated domain via the injected `TWENTY_FUNCTIONS_URL`. - New **"Public URL"** section on the application **Settings** tab explaining the isolated domain (shown when the app exposes HTTP-triggered functions). **Docs**: note the `withtwenty.com` domain for external callers in the apps guide. ## Infra prerequisites (not code — needs dashboard work) - Wildcard DNS `*.withtwenty.com` (proxied) + wildcard TLS in the public-domain Cloudflare zone. - Edge (Cloudflare) sets `X-Twenty-Public-Domain: true` for `*.withtwenty.com` requests, so the existing nginx ingress rewrites them onto `/s` (same header the custom-domain flow already relies on). - Set `PUBLIC_DOMAIN_URL=https://withtwenty.com` on cloud. - Submit `withtwenty.com` to the **Public Suffix List** (required for cross-tenant cookie isolation before relying on `Set-Cookie`). ## Test plan - [x] `nx typecheck twenty-server`, `nx typecheck twenty-front` - [x] `lint:diff-with-main` + oxfmt clean (server + front) - [x] `npx jest route-trigger public-function-domain domain-server-config workspace-domains build-logic-function-event client-config` → server unit tests passing (resolution tiers, header passthrough vs allow-list, `/s/` cutoff 410) - [x] `npx jest getLogicFunctionHttpUrl` (front) and `nx test twenty-client-sdk` (RestApiClient routing) passing - [x] CI green (server, front, sdk, renderer, ui, zapier, example apps) - [ ] Manual: hit `{subdomain}.withtwenty.com/` end-to-end once infra is provisioned <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22045?utm_source=github" rel="nofollow noreferrer noopener" target="_blank">``<img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg">``</a>

📝 Editing Content
Adding/Editing Pages
-
Edit MDX files in the appropriate directory:
user-guide/- User documentationdevelopers/- Developer documentationtwenty-ui/- Component documentation
-
Update
navigation/base-structure.jsonif you need to change the tab/group hierarchy or add/remove pages. This file stays in the repo and is not uploaded to Crowdin. -
Keep the translation template (
navigation/navigation.template.json) in sync by runningyarn docs:generate-navigation-templateafter editing the base structure. This template is the only file that should be pushed to Crowdin. -
For each translated locale pulled from Crowdin, ensure a
packages/twenty-docs/l/<language>/navigation.jsonfile exists. These files contain labels only; page slugs always come from the base structure. -
Run
yarn docs:generateto rebuilddocs.jsonfrom the base structure + translated labels.
