Lectful

Overview

This node integrates with the Lectful API to manage various resources related to online courses, users, content, and more. Specifically for the Image - Delete operation, it allows you to delete an image resource by its ID from the Lectful platform.

Common scenarios where this node is beneficial include:

• Automating cleanup of unused or outdated images in your course content.
• Managing media assets programmatically as part of a larger workflow (e.g., deleting images after course updates).
• Integrating image management into custom workflows without manual intervention.

Example use case:

• You have a workflow that processes course content updates and removes obsolete images automatically by deleting them via this node.

Properties

Output

The node outputs a JSON object representing the API response from the Lectful server after attempting to delete the specified image. Typically, this will be a confirmation of deletion or an error message if the deletion failed.

• The output is structured as an array of items, each containing a json property with the API response.
• No binary data is output by this operation.

Example output JSON structure on success might look like:

{
  "message": "Image deleted successfully",
  "id": "12345"
}

Or on failure:

{
  "error": "Image not found"
}

Dependencies

• Requires access to the Lectful API.
• Requires either stored credentials configured in n8n or manual entry of Base URL and API key.
• The API key must have permissions to delete images.
• No additional external dependencies beyond standard HTTP requests.

Troubleshooting

• Missing or invalid credentials:
  Error: "Valid credentials are required..."
  Solution: Ensure you have configured valid Lectful API credentials in n8n or provide correct Base URL and API key manually.

• Missing Image ID:
  Error occurs if the Image ID parameter is empty or invalid.
  Solution: Provide a valid Image ID of the image you want to delete.

• API errors such as "Image not found" or permission denied:
  Solution: Verify the Image ID exists and the API key has sufficient permissions.

• Network or connectivity issues:
  Solution: Check network connection and Lectful API availability.

• Using Manual Configuration but missing Base URL or API key:
  Error: "Base URL Override is required..." or "API Key Override is required..."
  Solution: Provide both Base URL Override and API Key Override parameters.
