Overview

This node integrates with a PDF Generator API to manage PDF templates and perform various PDF-related operations. Specifically, for the Template - Delete operation, it allows users to delete an existing PDF template by specifying its ID.

Common scenarios where this node is beneficial include:

  • Automating the cleanup of outdated or unused PDF templates in your document generation workflows.
  • Managing template lifecycle programmatically within larger automation pipelines.
  • Ensuring that only relevant templates remain accessible in your PDF generation system.

Practical example:

  • You have a workflow that periodically checks for deprecated templates and deletes them automatically using this node's Template Delete operation.

Properties

Name Meaning
Template Select the template to delete. You can choose from:
- From List: select a template from a searchable list.
- By ID: enter the numeric template ID directly (must be a number).

Output

The output JSON object after deleting a template includes:

  • success (boolean): Indicates if the deletion was successful (true).
  • message (string): Confirmation message, e.g., "Template deleted successfully".
  • templateId (string): The ID of the template that was deleted.

Example output JSON:

{
  "success": true,
  "message": "Template deleted successfully",
  "templateId": "12345"
}

No binary data is produced by this operation.

Dependencies

  • Requires an active connection to the PDF Generator API service.
  • Requires valid API credentials (an API key or token) configured in n8n for authentication.
  • The base URL for the API defaults to https://us1.pdfgeneratorapi.com/api/v4 but can be overridden via credentials.

Troubleshooting

Common Issues

  • Invalid Template ID: If the template ID is not provided or is not a number, the node will throw an error.
  • Template Not Found: Attempting to delete a non-existent template ID may result in an API error.
  • Authentication Errors: Missing or invalid API credentials will cause request failures.
  • Network Issues: Connectivity problems to the PDF Generator API endpoint will prevent operation completion.

Error Messages and Resolutions

  • "Template ID must be a number": Ensure the template ID input is numeric when entering manually.
  • "The operation "delete" is not supported for resource "template": Verify that the resource and operation parameters are correctly set.
  • Authentication errors typically indicate misconfigured or missing API credentials; verify and update credentials in n8n.
  • JSON parsing errors related to inputs usually mean malformed JSON in other operations, but for delete, this is unlikely.
