Vercel preview smoke gate with Slack review card
When a Vercel preview deploy succeeds, runs an HTTP smoke check against the preview URL and posts a pass/fail review card to Slack with the deploy link, status code, and latency.

The automated pipeline, trigger to output.

- ActionHTTP smoke request to preview URLHTTP webhook
- LogicDecide pass or fail on status + latency
- OutputPost pass/fail review card to SlackSlack
What it does
Every time a Vercel preview deployment reaches the ready state, this workflow hits the preview URL with a smoke request, evaluates the response, and posts a color-coded review card to your engineering Slack channel so reviewers see a clear pass or fail before they open the PR.
When to use it
Use it when your team relies on Vercel preview deploys for PR review and you want a fast automated sanity check — is the preview actually up and serving 200s — without anyone manually clicking the link first.
How it works
- 1A Vercel deployment-ready webhook fires with the preview URL and metadata.
- 2The flow filters to preview (not production) deployments only.
- 3An HTTP request hits the preview URL's health path and captures status code and response time.
- 4A logic step decides pass (2xx within the latency budget) or fail.
- 5A Slack message posts the review card — green for pass, red for fail — with the deploy URL, commit SHA, status code, and latency.
Set it up

- 1Connect VercelDeploys, runtime logs, analytics.
- 2Connect HTTP webhookTrigger any URL on agent actions.
- 3Connect SlackChannels, DMs, threads, mentions.
- 4Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
- 5Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
