n8n-nodes-rendex

n8n community node for Rendex — capture screenshots, generate PDFs, and render HTML to images via the Rendex rendering API.

This is a community node for n8n, the fair-code workflow automation platform. It lets your workflows talk to api.rendex.dev to render web pages and raw HTML into high-quality PNG, JPEG, WebP, or PDF output.

Features

• Capture screenshots of live URLs or raw HTML (up to 5 MB of HTML)
• Generate PDFs with configurable page size, margins, landscape, and scale
• Async mode — submit a capture and receive an HMAC-signed webhook when it's done
• Batch mode — submit up to 500 URLs in a single request (plan-dependent)
• Geo-targeted captures — render pages as seen from a specific country, city, or state (Pro/Enterprise)
• Element capture — screenshot a specific CSS selector instead of the full page
• Ad blocking, resource blocking, CSS/JS injection, cookie injection, custom headers, dark mode emulation, full-page auto-scroll

Rendex is built on Cloudflare Workers with Browser Rendering and backs a live v1.0.0 production API. See rendex.dev/docs for full API documentation.

Installation

n8n Cloud & self-hosted

1. Open your n8n instance → Settings → Community Nodes
2. Click Install and paste: n8n-nodes-rendex
3. Accept the community-node warning and click Install
4. Once installed, add a Rendex node to any workflow

Manual (npm)

npm install n8n-nodes-rendex

Authentication

1. Sign in to rendex.dev/dashboard (free plan available)
2. Go to API Keys and click Create Key
3. Copy the key — it starts with rdx_
4. In n8n, create a new Rendex API credential and paste the key into the API Key field

Rendex keys are bearer tokens sent as Authorization: Bearer rdx_.... The node handles the header automatically.

Operations

Screenshot

| Operation | What it does | |---|---| | Capture | Sync request that returns an image or PDF. Output is written to the node's binary property (default data) plus a JSON metadata object. | | Capture Async | Submits a job and returns immediately with a jobId. Optional webhookUrl is called with an HMAC-signed payload when the capture completes. |

Job

| Operation | What it does | |---|---| | Get Status | Polls an async job by jobId and returns its current status + signed result URL once ready. |

Batch

| Operation | What it does | |---|---| | Submit | Submits up to 500 URLs for parallel capture. Accepts per-URL defaults and an optional completion webhook. | | Get Status | Polls a batch by batchId and returns status + all child job results. |

Example: sync capture

1. Add a Rendex node after any trigger
2. Set Resource = Screenshot, Operation = Capture
3. Set Source = URL and enter https://example.com
4. Leave Format = png
5. Click Execute Node — the output tab shows the metadata JSON and the binary data property holds the PNG. Wire it into Write Binary File, Upload to S3, HTTP Request (to forward it), or any other binary-capable node.

Example: async + webhook trigger

1. Add a Rendex node, set Operation = Capture Async
2. Paste a webhook URL in the Webhook URL field (use another workflow's Webhook node production URL)
3. Execute. The first workflow returns immediately with the jobId.
4. In the receiving workflow, verify the HMAC signature on the rendex-signature header, then download the signed result URL from the payload.

Example: batch of URLs

1. Add a Rendex node, set Resource = Batch, Operation = Submit
2. Paste one URL per line in the URLs field
3. Fill Defaults (JSON) with shared options, e.g. {"format":"png","fullPage":true}
4. Execute — you get back a batchId and the list of queued jobs
5. Wire a Schedule Trigger or Wait node to another Rendex node with Resource = Batch, Operation = Get Status to poll completion.
