Generate and publish Instagram carousels with Gemini and Google Slides

Generate and publish Instagram carousels automatically Turn a single topic into a published Instagram Carousel in minutes.

Creating educational carousel posts usually takes hours: writing the script, designing the slides in Figma/Canva, exporting images, and scheduling. This workflow automates the entire pipeline using Gemini AI, Google Slides, and the Meta Graph API.

It generates the content, designs the visuals by manipulating a template, and publishes the carousel directly to your Instagram Business account.

🚀 What this workflow does 1. Script Generation: Runs daily (or on demand) to prompt Google Gemini to write a 6-slide educational script (Hook, Mistake, Why It Matters, Value, Tip, CTA). 2. Design Automation: - Copies a master Google Slides template. - Uses a "Find & Replace" operation to insert the AI-generated text into the correct placeholders. - Generates thumbnail images for each slide. 3. Image Hosting: Uploads the slide images to ImgBB to get public URLs (required by Meta's API). 4. Publishing: - Creates a carousel container on Instagram using the Meta Graph API. - Checks the container status until it is "FINISHED". - Publishes the media to your feed. 5. Logging: Records the post details, captions, and status in Google Sheets.

💡 Key Features - True Design Automation: Doesn't just overlay text on images; it uses real Google Slides templates, allowing for complex layouts and branding. - Smart Polling: Includes a "Wait & Check" loop to ensure the media container is fully processed by Facebook before attempting to publish (prevents API errors). - Structured Content: The AI is prompted to follow a proven "Viral Educational" framework (Hook -> Value -> Action). - Asset Management: Automatically organizes generated slide images and links in Google Sheets for your archives.
