N8N advanced URL parsing and shortening workflow - Switchy.io integration

# Advanced URL Parsing and Shortening Workflow with Switchy.io Integration

This n8n workflow provides a robust solution for processing and shortening URLs, integrating with Switchy.io for advanced link management. It's designed to automate the creation of short URLs based on input data, offering conditional logic to handle different scenarios.

## What it does

This workflow automates the following steps:

1.  **Triggers on Form Submission**: Initiates when a form is submitted, likely containing the long URL to be processed.
2.  **Initial Data Processing**: Edits the incoming fields, potentially extracting or transforming the submitted URL.
3.  **Conditional Logic (If Node)**: Evaluates the processed data.
    *   **True Branch**: If a certain condition is met (e.g., the URL is valid, or specific parameters are present), it proceeds to shorten the URL.
        *   **HTTP Request (Switchy.io)**: Makes an API call to Switchy.io to create a short URL.
        *   **Responds to Webhook**: Sends back the shortened URL or a success message.
    *   **False Branch**: If the condition is not met (e.g., the URL is invalid or missing), it handles the error.
        *   **Stop and Error**: Stops the workflow and signals an error.
        *   **Responds to Webhook**: Sends back an error message.
4.  **Loop Over Items (Optional/Advanced)**: The workflow includes a "Loop Over Items" node, suggesting it can process multiple URLs in batches if configured. This node is currently not connected in the provided JSON, indicating it might be an unutilized feature or a placeholder for future expansion.
5.  **HTML Processing (Optional/Advanced)**: An "HTML" node is present but not connected, implying potential for parsing HTML content, which could be used for extracting URLs from web pages or generating HTML responses.
6.  **Convert to File (Optional/Advanced)**: A "Convert to File" node, also unconnected, could be used for exporting processed data into various file formats.
7.  **Aggregate (Optional/Advanced)**: An "Aggregate" node, unconnected, could be used to combine data from multiple items or branches.
8.  **GitHub Node (Optional/Advanced)**: A GitHub node is present but unconnected, suggesting potential for integration with GitHub, perhaps for logging or triggering events.

## Prerequisites/Requirements

*   **n8n Instance**: A running instance of n8n.
*   **Switchy.io Account**: An active Switchy.io account with API access.
*   **Switchy.io API Key**: A Switchy.io API key configured as an n8n credential for the HTTP Request node.
*   **Form Submission Mechanism**: A method to submit data to the "On form submission" trigger node (e.g., a web form, another n8n workflow, or a direct API call to the webhook URL).

## Setup/Usage

1.  **Import the Workflow**: Import the provided JSON into your n8n instance.
2.  **Configure Credentials**:
    *   Locate the "HTTP Request" node.
    *   Configure the necessary Switchy.io API credentials. This typically involves setting up an "API Key" credential in n8n and selecting it in the HTTP Request node.
3.  **Configure the "On form submission" Trigger**:
    *   Activate the "On form submission" node.
    *   Note down the webhook URL generated by this node. This is where your form submissions will be sent.
4.  **Configure the "Edit Fields" (Set) Node**:
    *   Adjust the "Edit Fields" node to correctly extract and prepare the URL from your incoming form submission data. Ensure the field containing the long URL is correctly mapped.
5.  **Configure the "If" Node**:
    *   Define the conditions within the "If" node that determine whether a URL should be shortened or an error should be returned. This could be based on the presence of a URL, its validity, or other criteria.
6.  **Configure the "HTTP Request" Node**:
    *   Ensure the URL and body of the HTTP request are correctly configured to interact with the Switchy.io API for creating short links. You'll need to pass the long URL from the previous nodes to Switchy.io.
7.  **Configure "Respond to Webhook" Nodes**:
    *   Customize the success and error messages returned by the "Respond to Webhook" nodes to provide meaningful feedback to the form submitter or calling application.
8.  **Activate the Workflow**: Once configured, activate the workflow to start processing form submissions.

This workflow provides a flexible foundation for advanced URL management, with room for further customization and integration with other services.
