Integrate pdf noodle with n8n to automate your PDF generation workflows. Create invoices, reports, certificates, and any other documents automatically—no code required.

​
Prerequisites

Before you begin, make sure you have:

​
Setting Up the Integration

n8n connects to pdf noodle using the HTTP Request node.
1

Create a New Workflow

In n8n, create a new workflow and add your trigger (e.g., Webhook, Schedule, or any app trigger).
2

Add HTTP Request Node

Click the + button and search for HTTP Request.
3

Configure the Request

Set up the HTTP Request node:
SettingValue
MethodPOST
URLhttps://api.pdfnoodle.com/v1/pdf/sync
AuthenticationPredefined Credential Type → Header Auth
4

Set Up Authentication

Create a Header Auth credential:
SettingValue
NameAuthorization
ValueBearer YOUR_API_KEY
5

Configure the Body

Select Body → JSON and add:
{
  "templateId": "your-template-id",
  "data": {
    "customerName": "{{ $json.customer.name }}",
    "invoiceNumber": "{{ $json.order.id }}",
    "total": {{ $json.order.total }}
  }
}
Use n8n’s expression syntax to map data from previous nodes.

​
Finding Your Template ID

  1. Go to app.pdfnoodle.com
  2. Navigate to the Templates section
  3. Copy the Template ID shown in the list next to your template

​
Response

When the request succeeds, you’ll receive: 
{
  "signedUrl": "https://pdforge-production.s3.us-east-2.amazonaws.com/...",
  "metadata": {
    "executionTime": "1.805 seconds",
    "fileSize": "4.066 kB"
  }
}
Use the signedUrl in subsequent nodes to send via email, upload to storage, or attach to records.

​
Example Workflow

A typical workflow that generates an invoice when a new order is received:
  1. Webhook Trigger - Receives order data
  2. HTTP Request - Generates the PDF with pdf noodle
  3. Send Email - Sends the PDF to the customer using {{ $json.signedUrl }}

​
Error Handling

  • Verify your API key is correct
  • Ensure the Authorization header format is Bearer YOUR_API_KEY
  • Check your JSON syntax is valid
  • Ensure all required template variables are provided
  • Verify the template ID exists
  • Double-check the Template ID
  • Ensure the template exists in your pdf noodle account
