Overview

This node checks if a specific URL exists in the Wallabag read-it-later service. It is useful for workflows that need to verify the presence of an article or URL in Wallabag before performing further actions, such as avoiding duplicate saves or managing existing entries. For example, a user can input a URL and the node will return whether that URL is already saved in Wallabag, optionally returning the entry ID if it exists.

Use Case Examples

  1. Check if a news article URL is already saved in Wallabag before adding it to avoid duplicates.
  2. Verify the existence of a blog post URL in Wallabag to decide whether to update or create a new entry.

Properties

URL The URL to check if it exists in Wallabag, required for the existence check operation.

Output

JSON

  • exists - Indicates if the URL exists in Wallabag.
  • entry_id - The ID of the entry if the URL exists and the option to return it is enabled.

  • Common issues include authentication failures due to invalid or missing API credentials. The node will return an authentication error message in such cases.

  • Network or API endpoint issues can cause request failures; ensure the Wallabag service is reachable and the API endpoint is correct.
