Workflow Description:

Turn a simple text idea into production-ready icons in seconds. With this workflow, you input a subject (e.g., “Copy”, “Banana”, “Slack Mute”), select a style (Flat, 3D, Cartoon, etc.), and off it goes.

Here’s what happens:

  1. A form trigger collects your icon subject, style and optional background.
  2. The workflow uses an LLM to construct an optimised prompt.
  3. An image-generation model (OpenAI image API) renders a transparent-background, 400×400 px PNG icon.
  4. The icon is automatically uploaded to Google Drive, and both a download link and thumbnail are generated.
  5. A styled completion card displays the result and gives you a “One More Time” option.

Perfect for designers, developers, no-code creators, UI builders and even home-automation geeks (yes, you can integrate it with Home Assistant or Stream Deck!). It saves you the manual icon-hunt grind and gives consistent visual output across style variants.

🔧 Setup Requirements:

  • n8n instance (self-hosted or cloud)
  • OpenAI API access (image generation enabled)
  • Google Drive credentials (write access to a folder)
  • (Optional) Modify to integrate Slack, Teams or other file-storage destinations

✅ Highlights & Benefits:

  • Fully automated prompt creation → consistent icon quality
  • Transparent background PNGs size-ready for UI use
  • Saves icons to Drive + gives immediate link/thumbnail
  • Minimal setup, high value for creative/automation workflows
  • Easily extendable (add extra sizes, style presets, share via chat/bot)

⚠️ Notes & Best-Practices:

  • Check your OpenAI image quota and costs - image generation may incur usage.
  • Confirm Google Drive folder permissions to avoid upload failures.
  • If you wish a different resolution or format (e.g., SVG), clone the image node and adjust parameters.

Generate Custom Icons with OpenAI GPT Image & Google Drive Auto-Storage

This n8n workflow automates the process of generating custom icons using OpenAI's DALL-E model and then automatically storing the generated images in a specified Google Drive folder. It's triggered by a simple form submission, making it easy for anyone to request new icons.

What it does

  1. Triggers on Form Submission: The workflow starts when a user submits a form, providing a text description for the desired icon.
  2. Generates Icon Description with OpenAI Chat Model: It uses an OpenAI Chat Model (GPT) to refine or expand the user's icon description, ensuring it's suitable for image generation.
  3. Generates Image with OpenAI DALL-E: It then uses the refined description to generate an image (icon) using OpenAI's DALL-E model.
  4. Uploads Image to Google Drive: The generated image is automatically uploaded to a designated folder in Google Drive.
  5. Provides Form Output: The workflow concludes by providing output back to the form, likely including a link to the generated image or a confirmation message.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • OpenAI API Key: An OpenAI account with an API key configured for DALL-E image generation and Chat Model usage.
  • Google Drive Account: A Google account with Google Drive enabled and credentials configured in n8n.
  • Google Drive Folder ID: The ID of the Google Drive folder where you want to store the generated icons.

Setup/Usage

  1. Import the workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • OpenAI: Set up your OpenAI API key credential in n8n.
    • Google Drive: Set up your Google Drive OAuth2 credential in n8n.
  3. Configure Nodes:
    • "OpenAI Chat Model" Node: Ensure your OpenAI credential is selected. You might want to adjust the prompt for refining the icon description based on your needs.
    • "OpenAI" Node: Ensure your OpenAI credential is selected.
    • "Google Drive" Node:
      • Select the correct Google Drive credential.
      • Specify the Folder ID where the generated images should be uploaded.
      • Map the incoming image data from the OpenAI node to the Google Drive upload operation.
    • "n8n Form Trigger" Node: This node will automatically create a public form URL once the workflow is activated. You can customize the form fields if needed, but by default, it expects a text input for the icon description.
    • "Form" Node: This node defines the output that will be displayed to the user after form submission. You'll likely want to include the URL of the uploaded Google Drive image here.
  4. Activate the workflow: Once configured, activate the workflow.
  5. Use the Form: Access the URL provided by the "n8n Form Trigger" node, enter your icon description, and submit the form. The workflow will then generate and store your custom icon.

Automate Dutch Public Procurement Data Collection with TenderNed

TenderNed Public Procurement What This Workflow Does This workflow automates the collection of public procurement data from TenderNed (the official Dutch tender platform). It: Fetches the latest tender publications from the TenderNed API Retrieves detailed information in both XML and JSON formats for each tender Parses and extracts key information like organization names, titles, descriptions, and reference numbers Filters results based on your custom criteria Stores the data in a database for easy querying and analysis Setup Instructions This template comes with sticky notes providing step-by-step instructions in Dutch and various query options you can customize. Prerequisites TenderNed API Access - Register at TenderNed for API credentials Configuration Steps Set up TenderNed credentials: Add HTTP Basic Auth credentials with your TenderNed API username and password Apply these credentials to the three HTTP Request nodes: "Tenderned Publicaties" "Haal XML Details" "Haal JSON Details" Customize filters: Modify the "Filter op ..." node to match your specific requirements Examples: specific organizations, contract values, regions, etc. How It Works Step 1: Trigger The workflow can be triggered either manually for testing or automatically on a daily schedule. Step 2: Fetch Publications Makes an API call to TenderNed to retrieve a list of recent publications (up to 100 per request). Step 3: Process & Split Extracts the tender array from the response and splits it into individual items for processing. Step 4: Fetch Details For each tender, the workflow makes two parallel API calls: XML endpoint - Retrieves the complete tender documentation in XML format JSON endpoint - Fetches metadata including reference numbers and keywords Step 5: Parse & Merge Parses the XML data and merges it with the JSON metadata and batch information into a single data structure. Step 6: Extract Fields Maps the raw API data to clean, structured fields including: Publication ID and date Organization name Tender title and description Reference numbers (kenmerk, TED number) Step 7: Filter Applies your custom filter criteria to focus on relevant tenders only. Step 8: Store Inserts the processed data into your database for storage and future analysis. Customization Tips Modify API Parameters In the "Tenderned Publicaties" node, you can adjust: offset: Starting position for pagination size: Number of results per request (max 100) Add query parameters for date ranges, status filters, etc. Add More Fields Extend the "Splits Alle Velden" node to extract additional fields from the XML/JSON data, such as: Contract value estimates Deadline dates CPV codes (procurement classification) Contact information Integrate Notifications Add a Slack, Email, or Discord node after the filter to get notified about new matching tenders. Incremental Updates Modify the workflow to only fetch new tenders by: Storing the last execution timestamp Adding date filters to the API query Only processing publications newer than the last run Troubleshooting No data returned? Verify your TenderNed API credentials are correct Check that you have setup youre filter proper Need help setting this up or interested in a complete tender analysis solution?
