Overview

This node integrates with the TailURL API to perform URL shortening, QR code generation, webhook management, and analytics retrieval. Specifically, the "Generate QR Code" operation creates a QR code image for a given URL, which can be used in marketing materials, product packaging, event tickets, or any scenario where quick access to a URL via scanning is desired.

Practical examples:

  • Generate a QR code for a shortened URL to print on flyers.
  • Create QR codes of different sizes for embedding in emails or websites.
  • Automate QR code creation as part of a workflow that shortens URLs and shares them.

Properties

Name Meaning
Target URL The URL for which the QR code will be generated.
QR Code Size The size of the QR code image. Options: Small (200x200), Medium (400x400), Large (800x800)

Output

The node outputs JSON data containing the response from the TailURL API after generating the QR code. This typically includes details about the created shortened URL along with embedded QR code information such as the image data or URL to the QR code image.

If binary data is returned (e.g., the QR code image itself), it would represent the QR code image in the specified size and colors, ready for use or download.

Dependencies

  • Requires an API key credential for authenticating with the TailURL API.
  • Network access to https://tailurl.com/api/ endpoints.
  • Proper configuration of the TailURL API credentials within n8n.

Troubleshooting

  • Common issues:

    • Invalid or missing API key credential will cause authentication failures.
    • Providing an invalid or empty URL for QR code generation will result in errors.
    • Network connectivity issues may prevent successful API calls.

  • Error messages:

    • "Failed to get analytics: ..." or similar messages indicate API request failures; check the error details for causes.
    • "Unknown operation: generateQr" would occur if the operation parameter is incorrect or unsupported.
    • Authentication errors often mention unauthorized access; verify API key validity and permissions.

  • Resolutions:

    • Ensure the API key credential is correctly set up and has necessary permissions.
    • Validate input URLs before running the node.
    • Check network connectivity and firewall settings.
