Automation Integrations

Generate images, screenshots and PDFs inside Make, Zapier, n8n, or any automation platform with an HTTP request module.

Common connection

All platforms use the same REST API. Create an API key in the StarkRender dashboard, keep it in the platform's secure connection or credential store, and send it in the x-api-key header.

{
  "html": "<div style='width:1080px;height:1080px;display:flex;background:#111;color:#fff'>Hello</div>",
  "width": 1080,
  "height": 1080,
  "image_url": "https://example.com/photo.jpg"
}

{
  "url": "https://api.starkrender.com/v1/image/uuid",
  "id": "uuid"
}

Make

HTTP module

1. Add HTTP → Make a request to your scenario.
2. Set the URL to https://api.starkrender.com/v1/render or /v1/render/fast.
3. Select POST, add the x-api-key header, and choose application/json.
4. Map values from previous modules into html and image_url.
5. Use the returned url in the next module.

Custom app operation

{
  "url": "/v1/render/fast",
  "method": "POST",
  "body": {
    "image_url": "{{parameters.image_url}}",
    "html": "{{parameters.html}}"
  },
  "response": {
    "output": { "url": "{{body.url}}" }
  }
}

Zapier

1. Add Webhooks by Zapier → Custom Request.
2. Choose POST and enter https://api.starkrender.com/v1/render.
3. Set Data Pass-Through to false and provide a JSON body.
4. Add headers x-api-key and Content-Type: application/json.
5. Test the step, then map the response field url into your storage, social, email, or publishing action.

{
  "html": "{{HTML from previous step}}",
  "image_url": "{{Image URL from previous step}}",
  "width": 1080,
  "height": 1350
}

n8n

1. Add an HTTP Request node.
2. Set method to POST and URL to https://api.starkrender.com/v1/render.
3. Use Header Auth or add x-api-key manually.
4. Enable Send Body, select JSON, and map expressions from earlier nodes.
5. Read the image URL with {{$json.url}} in the next node.

{
  "html": "{{$json.html}}",
  "image_url": "{{$json.image_url}}",
  "width": 1080,
  "height": 1350
}

Other automation tools

The same configuration works in Pipedream, Activepieces, Node-RED, Power Automate, Retool, Bubble, Airtable automations, serverless functions, and any system that can send an authenticated HTTP request.

• Use /v1/render/fast for low-latency, Satori-compatible HTML/CSS.
• Use /v1/render for Chromium rendering and broader web compatibility.
• Use /v1/render/async when the automation platform has a short request timeout.
• Use /v1/render/batch to create up to 25 images in one operation.
• Use /v1/screenshot for public web pages and /v1/pdf for PDF documents.
