Overview

This node interacts with a user-related API to check if the current authenticated user is following another specified user. It is useful in scenarios where you want to verify social connections or relationships between users, such as in social networks, collaboration platforms, or any system that supports user following functionality.

For example, you might use this node to:

  • Determine if the logged-in user follows a particular username before showing personalized content.
  • Automate notifications or actions based on follow status.
  • Build dashboards displaying follow relationships dynamically.

Properties

Name Meaning
Username The username of the user to check if the current user is following. This is a required string input.

Output

The node outputs JSON data indicating whether the current user follows the specified username. The exact structure is not fully detailed in the provided code, but typically it would include a boolean or status field confirming the follow relationship.

If the node supports binary data output, it is not evident from the source code provided.

Dependencies

  • Requires an API key or authentication token credential to access the user API securely.
  • Needs the base URL of the API endpoint configured in credentials.
  • Depends on the external API service that manages user follow relationships.

Troubleshooting

  • Common issues:

    • Invalid or missing API credentials will cause authentication failures.
    • Providing a non-existent username may result in errors or empty responses.
    • Network connectivity problems can prevent API calls from succeeding.

  • Error messages and resolutions:

    • Authentication errors: Verify that the API key or token is correctly set up and has necessary permissions.
    • User not found: Confirm the username exists and is spelled correctly.
    • Timeout or network errors: Check internet connection and API server status.

Links and References

  • Refer to the API documentation of the user service for details on the "check following" endpoint.
  • n8n documentation on creating and using credentials for API authentication.
