Overview

The node provides a variety of PDF and image processing operations through the Pdf4me service. Specifically, the "Get Document From Pdf4me" operation retrieves a document from the Pdf4me platform by specifying the source PDF file name and a callback URL. This operation is useful when you want to fetch or download a processed PDF document that has been handled or generated by Pdf4me.

Common scenarios include:

  • Automating workflows where PDFs are processed externally and then retrieved back into n8n for further use.
  • Integrating with Pdf4me to get documents after applying transformations or analyses.
  • Using the callback URL to notify or trigger other systems once the document retrieval is complete.

Example: You have a PDF document named "invoice.pdf" processed on Pdf4me, and you want to retrieve it automatically in your workflow by providing its filename and a callback URL to receive notifications or results.

Properties

Name Meaning
File Name The name of the source PDF file to retrieve from Pdf4me (e.g., "document.pdf").
Callback URL A URL to be called back by the service, typically used for notifications or result delivery (e.g., "https://www.google.com").

Output

The output of this operation is an array of JSON objects representing the retrieved document(s) from Pdf4me. Each item contains the data related to the fetched PDF document. If the node supports binary data output (common for files), the binary field will contain the actual PDF file content.

  • json: Metadata or information about the retrieved document.
  • binary (if applicable): The actual PDF file content as binary data.

Dependencies

  • Requires access to the Pdf4me API service.
  • Needs proper API authentication credentials configured in n8n to connect securely to Pdf4me.
  • The callback URL must be accessible and able to receive HTTP requests if used for notifications.

Troubleshooting

  • Common issues:

    • Incorrect or missing file name may cause the document not to be found.
    • Invalid or unreachable callback URL can lead to failed notifications or callbacks.
    • Authentication errors if API credentials are not set up correctly.
  • Error messages:

    • "Document not found": Verify the file name is correct and exists on Pdf4me.
    • "Callback URL invalid": Ensure the URL is properly formatted and reachable.
    • Authentication failures: Check API key or token validity and permissions.

Resolving these usually involves verifying input parameters, ensuring network connectivity, and confirming credential configurations.
