In this quick walkthrough, I show you exactly how to integrate it with n8n using an HTTP request node. Learn how to send prompts, convert base64 to binary, and automate image handling. This is a big one. Don’t miss it.\n\n🔗 Official API Overview: https://openai.com/index/image-generation-api/\n🔗 API Reference – Create Image: https://platform.openai.com/docs/api-reference/images/create\n\n### *New:  Make.com scenario here: https://drive.google.com/file/d/1Uz-mA0LnUZ_tnUWBR2AAlVxs3LBlGKfk/view?usp=sharing\n"
