# Introduction
Getting rid of the fine grained PAT used to dispatch to internal
repositories.
Repo dispatch requires the contents write permissions which is too wide
for such use
Refactored all senders and target to pass through a workflow dispatch
instead
Creating a centralize app that forges a token with actions: write only
provided permissions to mitigate any token exfiltrations
## Summary
Adds review apps for the marketing site. Every PR that touches
`packages/twenty-website/**` or `packages/twenty-shared/**` gets a
per-version Worker preview URL, sticky-commented on the PR, auto-cleaned
up when the PR closes.
Same Cloudflare machinery skew protection rides on, just used for
previews — no extra plan, no extra services. Cleaner than the
GitHub-Actions-runner + Cloudflare-tunnel pattern: previews persist for
the life of the version, accessible from anywhere, no warm-up.
## Files
- **`.github/workflows/website-pr-preview.yaml`** — on PR
open/sync/reopen: builds the Worker with a per-PR `DEPLOYMENT_ID`, runs
`wrangler versions upload --tag pr-<N>` (no production traffic),
sticky-comments the preview URL. Skipped on fork PRs because GitHub
doesn't pass secrets to forks anyway.
- **`.github/workflows/website-pr-preview-cleanup.yaml`** — on PR close:
walks the Worker version list via the CF API, deletes anything tagged
`pr-<N>` (with message-based fallback if the annotation key changes),
updates the sticky comment.
- **`open-next.config.ts`** — `maxNumberOfVersions: 10 → 50` to leave
room for PR previews on top of skew protection's prod-version retention.
## How it looks on a PR
The bot leaves a sticky comment like:
> 🔍 **Website preview** is up at
**https://abc12345-twenty-website-dev.twentyhq.workers.dev**
>
> | | |
> |---|---|
> | Version | `abc12345-...` |
> | Commit | `<sha>` |
> | Bindings | shared with the `dev` Worker (R2 cache + secrets) |
>
> Updates on every push. Auto-deleted when the PR closes.
On close it becomes:
> 🧹 Website preview for this PR was cleaned up after close.
## Twenty repo credentials already provisioned
- `secret CLOUDFLARE_API_TOKEN` — same scoped token the `twenty-infra`
workflow uses
- `var CLOUDFLARE_ACCOUNT_ID` = `67b2bbe4381006564d2b0aa6ce6177be`
- `var CF_PREVIEW_DOMAIN` = `twentyhq` (no `.workers.dev` suffix —
OpenNext appends it;
[opennextjs-cloudflare#811](https://github.com/opennextjs/opennextjs-cloudflare/issues/811))
## Known limitations
- **Shared dev bindings**: PR previews use the dev Worker's R2 bucket +
secrets (Stripe test key, JWT private key). Fine for a read-mostly
marketing site; if two simultaneous PRs ever fight over ISR cache state
we can prefix R2 keys per-PR later.
- **Fork PRs don't get previews**. GitHub Actions doesn't pass
`secrets.*` to fork-PR runs (security), and the wrangler upload requires
the CF token. To enable forks, would need to switch to
`pull_request_target` and gate on a maintainer label — not done here
because the security tradeoff isn't worth it for a marketing-site
preview.
- **Version cap**: 50 versions is the new ceiling, and
`maxVersionAgeDays: 14` auto-prunes anything older. Cleanup-on-close
should keep us well under in steady state.
## Test plan
- [ ] CI on this PR triggers the preview workflow itself; check that the
sticky comment appears with a working URL
- [ ] Hit the URL, click around — should look like a fresh
marketing-site build with this PR's changes
- [ ] Close (don't merge) → cleanup workflow should run; sticky comment
switches to the "cleaned up" message; the version is gone from `wrangler
versions list --name twenty-website-dev`
