Generate PDFs in n8n Workflows

Generate PDFs directly in your n8n workflows using HTML2PDFAPI. Just 3 steps: add an HTTP Request node, copy a cURL command, and import it. No manual configuration needed.

Why Use HTML2PDFAPI with n8n?

No-Code PDF Generation

Import a cURL command and you're done, no manual configuration required.

Dynamic Templates

Use n8n expressions to inject data from previous nodes directly into your PDF content.

Reliable Rendering

Chromium-based rendering ensures your PDFs look exactly like they do in the browser.

Fast Processing

Optimized for automation workflows with quick response times and high availability.

3-Step Setup

Step 1: Add HTTP Request Node

In your n8n workflow, click the + button and add an HTTP Request node.

Step 2: Get Your cURL Command

Sign up and use the playground to configure your PDF options and copy the cURL command. Or use this default test command:

curl -X POST https://html2pdfapi.com/api/render \
  -H "Content-Type: application/json" \
  -d '{
    "apiKey": "YOUR_API_KEY",
    "async": false,
    "html": "<html><body><h1>Hello World</h1></body></html>",
    "format": "pdf",
    "pdf": {
      "format": "A4",
      "printBackground": true
    }
  }'

Note: async: false means the request waits for the PDF before responding. Recommended for n8n.

Step 3: Import cURL and Run

In the HTTP Request node, click "Import cURL" and paste your command. Execute the node to test, then connect any downstream nodes (email, storage, Slack, etc).

Request Body Examples

Dynamic HTML Template

Use n8n expressions to inject data from previous nodes:

{
  "apiKey": "YOUR_API_KEY",
  "async": false,
  "html": "<html><body><h1>Invoice #{{ $json.invoiceNumber }}</h1><p>Amount: {{ $json.amount }}</p></body></html>",
  "format": "pdf",
  "pdf": {
    "format": "A4",
    "margin": { "top": "20mm", "bottom": "20mm" }
  }
}

Convert URL to PDF

Convert any webpage to PDF by passing a URL:

{
  "apiKey": "YOUR_API_KEY",
  "async": false,
  "url": "https://your-app.com/report/{{ $json.reportId }}",
  "format": "pdf",
  "pdf": { "format": "A4", "printBackground": true }
}

Common Workflow Examples
