Automate Image Generation with OpenAI DALL-E 3 via Webhook
Create an API endpoint that generates images using OpenAI's DALL-E 3 based on URL-encoded prompts, without exposing your API key.
This workflow sets up a public API endpoint using n8n's webhook capabilities, allowing users to generate images with OpenAI's DALL-E 3. By appending a URL-encoded prompt to the webhook URL, the workflow triggers image generation and returns the result directly to the user's browser. This setup ensures your OpenAI API key remains secure while providing a seamless image generation service.
