n8n node to interact with WB API

Actions5

Overview

This node is designed to interact with a document management API, specifically to download all documents in bulk. It allows users to send custom parameters as JSON in the request body to filter or specify which documents to download. This functionality is useful in scenarios where you need to automate the retrieval of multiple documents at once, such as batch processing invoices, reports, or any other document types managed by the system.

Practical examples include:

  • Downloading all financial documents for a given period.
  • Retrieving all contract documents matching certain criteria.
  • Automating backup of all documents stored in the system.

Properties

Name Meaning
Params A JSON object containing parameters to customize the download request. Users can specify filters or options supported by the API to control which documents are downloaded.

Output

The node outputs JSON data representing the response from the document download API. The exact structure depends on the API but typically includes metadata about the documents and possibly links or encoded content for the downloaded files.

If the node supports binary data output (not explicitly shown in the code), it would represent the actual document files downloaded, allowing further processing or saving within n8n workflows.

Dependencies

  • Requires an API key credential for authentication with the external document management service.
  • Depends on the base URL and API schema defined in an imported JSON swagger file.
  • Uses an OpenAPI helper library to build properties and handle requests.
  • No additional environment variables are explicitly required beyond standard API credentials.

Troubleshooting

  • Invalid JSON in Params: Since the Params property expects valid JSON, malformed input will cause errors. Ensure the JSON syntax is correct.
  • Authentication Errors: Missing or invalid API credentials will result in authorization failures. Verify that the API key or token is correctly configured.
  • API Endpoint Issues: If the base URL or endpoint changes, the node may fail to connect. Confirm the API URL is up to date.
  • Empty or Unexpected Response: If no documents match the parameters, the output might be empty or contain error messages. Adjust the parameters accordingly.

Links and References

  • Refer to the external document management API documentation for details on supported parameters and response formats.
  • OpenAPI specification used for this node is located in the bundled swagger JSON file (12-finances_modified.json).
