Description

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.

🛠️ Prerequisites

• Google Cloud: Enabled APIs for Drive, Slides, Sheets, and Gemini.
• Meta Developer App: An Instagram Business account connected to a Facebook Page, with a System User token (instagram_basic, instagram_content_publish, pages_read_engagement).
