Artikel und Branchen aus der Wawi abrufen

Actions2

Overview

This node connects to a Wawi (merchandise management) system API to retrieve either articles or industry sectors data. It is useful for workflows that need to integrate product or business sector information from the Wawi system into n8n for further processing, reporting, or synchronization with other systems.

Practical examples:

  • Automatically fetching updated product lists to sync with an e-commerce platform.
  • Retrieving industry categories to classify customer data or generate reports.

Properties

Name Meaning
API Key Your API key used for authenticating requests to the Wawi API.
Operation The type of data to retrieve: "Artikel Abrufen" (Get Articles) or "Branchen Abrufen" (Get Industries).

Output

The node outputs a single JSON array containing the data retrieved from the Wawi API endpoint corresponding to the selected operation. The structure of the JSON depends on the API response for either articles or industries.

No binary data output is produced by this node.

Example output structure (simplified):

[
  {
    "id": "...",
    "name": "...",
    "otherFields": "..."
  },
  ...
]

Dependencies

  • Requires access to the Wawi API endpoints at http://wawi24.test/api/artikel or http://wawi24.test/api/branchen.
  • An API key credential must be provided for authentication via the Authorization header.
  • No additional external libraries beyond standard HTTP request helpers are needed.

Troubleshooting

  • Common issues:

    • Invalid or missing API key will likely cause authentication errors.
    • Network connectivity problems or incorrect base URL may result in request failures.
    • Selecting an unsupported operation value could lead to empty or failed requests.

  • Error messages and resolutions:

    • Authentication errors: Verify the API key is correct and has necessary permissions.
    • Request timeouts or connection refused: Check network access to the API server and ensure the URL is reachable.
    • Unexpected response format: Confirm the API endpoint is returning valid JSON and matches expected schema.

Links and References

  • Wawi API documentation (if available) should be consulted for detailed data schemas and authentication requirements.
  • n8n HTTP Request node documentation for understanding request options and error handling.
