Rendex for Zapier

Drop the native Rendex action into any Zap to turn HTML, a URL, or Markdown into a screenshot, thumbnail, OG image, or PDF — then send it on to Slack, Drive, Sheets, or 7,000+ other apps.

Rendering as a no-code Zapier action: pick a preset, map your fields, and let Rendex hand a finished image or PDF to the next step — or a hosted og:image link the next step can embed anywhere. Async jobs resolve automatically via polling, with an optional catch hook for instant callbacks.

# Example Zap: Weekly competitor screenshot to Slack
Trigger  ->  Schedule by Zapier — Every Monday 9am
Action   ->  Rendex — Capture Screenshot
             url      = https://competitor.com
             format   = png
             fullPage = true
Action   ->  Slack — Send file to #market-intel
             file = {{Rendex.file}}

How It Fits Your Workflow

A Zapier zap: a new Airtable record triggers the Rendex Capture Screenshot action, which attaches the rendered image back to the Airtable record.

Trigger

Any of Zapier's 7,000+ apps — a new row, form submission, schedule, or webhook.

Rendex action

Capture Screenshot, Render HTML, or Generate PDF — choose a preset and map your data.

Downstream

Post the file to Slack, upload to Google Drive, attach a row in Sheets, or email it.

What You Can Do

Native action in the editor

Search "Rendex" in the Zapier app directory, connect your API key once, and the Capture Screenshot / Render HTML / Generate PDF actions appear right in the Zap editor — no custom webhooks to wire.

Screenshots, PDFs, and batch

Render a full-page screenshot, social card, thumbnail, OG image, or multi-page PDF from a URL, raw HTML, or Markdown. Submit a list of URLs in one batch step.

Polling + webhook for async

Long renders run as async jobs. Zapier polls until the file is ready, or you can wire a Catch Hook for an instant callback when the job completes — no busy-waiting in your Zap.

Website-change monitoring (Watch)

Beyond one-off renders, Rendex Watch checks a page on a schedule and fires only when it changes — a real-Chrome before/after visual diff. Route the change into a Zap to alert Slack, log a row, or open a ticket. Watch runs on Free (1 watch, a daily check, email alerts); faster checks and more watches come with Starter and Pro.

Test a watch before you start monitoring

The Test a Website Watch action tries a watch on a page once, right now, without creating it. Rendex captures the page a single time and tells you whether it could read it and what it saw — so you can confirm the page works and your settings are right before you commit to scheduled monitoring. Nothing is saved and no alerts are set up.

Retries, logging, and errors

Failed renders surface as clear, structured errors that Zapier can retry or branch on, and every run is logged in your Zap history for easy debugging.

Map data into templates

Pass values from earlier steps into Rendex's Mustache data fields to populate dynamic HTML or Markdown templates — personalized cards, receipts, and reports per run.

Create Render Link — hosted og:image links

Need a permanent og:image link instead of a file to pass between steps? The Create Render Link action turns a URL, HTML, or Markdown into a hosted, auto-caching image or PDF link. Rendex renders it once on the first view, then serves the edge-cached copy on every share — write the returned URL straight into a CMS og:image field, a SharePoint/Sheets column, or a Slack post.

No infrastructure

No headless browser, no servers, no Puppeteer to maintain. Rendex handles the rendering; you just connect the action. Start free with 100 renders/month, no card required.

Popular Zaps — one-click templates

Pre-built and published — copy one into your account in a click, no steps to wire. Open the walkthrough if you'd rather build it by hand.

Zapier
