Configure your own image creation API using OpenAI DALLE-3
How it works: Webhook URL that responds to Requests with an AI generated Image based on the prompt provided in the URL.
Setup Steps:
- Ideate your prompt
- URL Encode The Prompt (as shown in the Template)
- Authenticate with your OpenAI Credentials
- Put together the Webhook URL with your prompt and enter into a webbrowser
In this way you can expose a public url to users, employee's etc. without exposing your OpenAI API Key to them.
Configure Your Own Image Creation API Using OpenAI DALL-E 3
This n8n workflow simplifies the process of creating a custom API endpoint for generating images using OpenAI's DALL-E 3. It acts as a bridge, allowing you to trigger image generation through a simple HTTP request and receive the generated image details as a response.
What it does
- Listens for incoming requests: The workflow starts by exposing a webhook endpoint. When an HTTP POST request is sent to this endpoint, the workflow is triggered.
- Generates image with DALL-E 3: It takes the input from the incoming webhook, likely a text prompt for image generation, and sends it to the OpenAI DALL-E 3 model.
- Responds to the webhook: After the image is generated by DALL-E 3, the workflow captures the response (e.g., the URL of the generated image) and sends it back as the response to the original HTTP request that triggered the workflow.
Prerequisites/Requirements
- n8n Instance: A running instance of n8n (self-hosted or cloud).
- OpenAI Account & API Key: An OpenAI account with access to the DALL-E 3 API and a valid API key. This key will need to be configured as an n8n credential.
Setup/Usage
- Import the workflow:
- Copy the provided JSON code.
- In your n8n instance, click "New Workflow".
- Go to "File" > "Import from JSON" and paste the code.
- Configure OpenAI Credentials:
- Locate the "OpenAI" node in the workflow.
- Click on the "Credential" field and select "Create New Credential".
- Choose "OpenAI API" as the credential type.
- Enter your OpenAI API Key.
- Save the credential.
- Activate the Webhook:
- Locate the "Webhook" node.
- Copy the "Webhook URL" displayed in the node's settings. This is the URL you will send your image generation requests to.
- Test the workflow:
- Enable the workflow.
- Send an HTTP POST request to the copied Webhook URL. The request body should contain the prompt for the image you want to generate. For example, a JSON body like
{"prompt": "a futuristic city at sunset, digital art"}. - The workflow will process the request, generate the image, and return the image details (e.g., a URL to the image) in the webhook response.
This workflow provides a powerful and flexible way to integrate DALL-E 3 image generation into your applications or other workflows with minimal code.

By Daniel NkenchoSynchronizing WooCommerce inventory and creating products with Google Gemini AI and BrowserAct
Synchronize WooCommerce Inventory & Create Products with Gemini AI & BrowserAct This sophisticated n8n template automates WooCommerce inventory management by scraping supplier data, updating existing products, and intelligently creating new ones with AI-formatted descriptions. This workflow is essential for e-commerce operators, dropshippers, and inventory managers who need to ensure their product pricing and stock levels are synchronized with multiple third-party suppliers, minimizing overselling and maximizing profit. --- Self-Hosted Only This Workflow uses a community contribution and is designed and tested for self-hosted n8n instances only. --- How it works The workflow is typically run by a Schedule Trigger (though a Manual Trigger is also shown) to check stock automatically. It reads a list of suppliers and their inventory page URLs from a central Google Sheet. The workflow loops through each supplier: A BrowserAct node scrapes the current stock and price data from the supplier's inventory page. A Code node parses this bulk data into individual product items. It then loops through each individual product found. The workflow checks WooCommerce to see if the product already exists based on its name. If the product exists: It proceeds to update the existing product's price and stock quantity. If the product DOES NOT exist: An If node checks if the missing product's category matches a predefined type (optional filtering). If it passes the filter, a second BrowserAct workflow scrapes detailed product attributes from a dedicated product page (e.g., DigiKey). An AI Agent (Gemini) transforms these attributes into a specific, styled HTML table for the product description. Finally, the product is created in WooCommerce with all scraped details and the AI-generated description. Error Handling: Multiple Slack nodes are configured to alert your team immediately if any scraping task fails or if the product update/creation process encounters an issue. Note: This workflow does not support image uploads for new products. To enable this functionality, you must modify both the n8n and BrowserAct workflows. --- Requirements BrowserAct API account for web scraping BrowserAct n8n Community Node -> (n8n Nodes BrowserAct) BrowserAct templates named “WooCommerce Inventory & Stock Synchronization” and “WooCommerce Product Data Reconciliation” Google Sheets credentials for the supplier list WooCommerce credentials for product management Google Gemini account for the AI Agent Slack credentials for error alerts --- Need Help?
