Method #01: Installing pdf noodle Node in n8n

We recommend you use our native node to make it easier for you to start generating our PDFs. It works either if you're using n8n cloud version or n8n self-hosted version (we have a guide on how to do it here).

The oficial pdf noodle node is the easiest way to integrate pdf noodle with n8n. You can find the node in our [Github repository](https://github.com/pdfnoodle/n8n-nodes-pdf noodle) but it will automatically appear for you in your search bar, inside n8n. All you need to do is click to install the node on your n8n interface, following this steps:

Search "pdf noodle" node inside any n8n workflow and click "Install node".
Select the node and enter your **API Key **
Choose the PDF template you created in pdf noodle and the **output format (PDF/PNG) **
Map input variables from previous nodes (e.g., form submissions, API responses).

Hint: You can see all the variables you need to fill on your template page
Execute the workflow to test the PDF generation.

This method ensures a low-code, hassle-free setup with native compatibility.

Method #02: Using HTTP Request Node in n8n (hosted by n8n)

If you want to, you can use our easy to use API (Heres the documentation) to connect n8n or any other software with pdf noodle. To make an API connection with pdf noodle, you'll need to use the HTTP Request node.

Here's the information that you're going to need:

Method: POST
URL: https://api.pdfnoodle.com/v1/pdf/sync
Authentication: none
Send Headers -> Authorization : Bearer {{your_api_key_here}}

Send Body -> Body Content Type: JSON:

{
  "template_id": "your_template_id_here", //Template ID here
  "convertToImage": false, //true if you want the output to be PNG
  "data":{} //your_variables_here
}

You can get all these information on the template visualization, on the "No-Code" tab, inside pdf noodle's application:

In case you need to know more about the parameters, you can access the full documentation here.

In a step-by-step process:

Add an HTTP Request node to your workflow
Set the method to POST and enter the pdf noodle API URL
Include the required headers (e.g., authentication token)
In the body, pass the JSON payload containing template ID, output format (PNG/PDF) and variables data
Execute the workflow and retrieve the generated PDF URL.

This method is useful for customized API calls, advanced error handling, or integrating pdf noodle with multiple services within n8n.

Connecting Other Nodes to Your n8n Workflow

• Storage nodes: Save the generated PDF to Google Drive, AWS S3, or a local server.

• Email nodes: Automatically send PDFs as email attachments to customers, employees, or leads.

• CRM nodes: Attach generated PDFs to client records in HubSpot, Salesforce, or Airtable.

By combining multiple nodes, complex workflows can be automated with minimal human intervention.
