Have ChatGPT output structured JSON: {title, content_html, categories[], featured_image_url, publish_date (ISO)}. In Zapier: trigger from webhook or new ChatGPT reply -> parse JSON -> Upload Media (from featured_image_url) -> Create Post with Post Status = future and Post Date = publish_date; map categories. Test with one draft to confirm category/feature-image IDs. I can paste a ready JSON prompt if helpful.
