Workflow overview
Why this workflow matters
Potentially useful as a reusable automation building block.
A fully automated AlekSystem workflow that runs every day at 1:10 PM IST and publishes a fresh AI-generated image to Instagram — zero manual effort required after setup. It reads content ideas from a Google Sheet, uses GPT-4.1 Nano to craft a cinematic image prompt and a niche-matched caption, generates the image with Google Gemini 2.5 Flash, uploads it to a public CDN called Upload to Url (https://uploadtourl.com) , posts it to Instagram, and logs everything back to the sheet. ✨ What This Workflow Does Triggers daily at 1:10 PM IST via Schedule Trigger Fetches a pending idea from a Google Sheet where Status = "Ready" Generates an image prompt + caption using GPT-4.1 Nano — tailored to the niche's aesthetic (luxury, minimalist, vibrant, etc.) Creates the image using Google Gemini 2.5 Flash Image model Uploads the image to a public CDN via UploadToURL (https://uploadtourl.com) Posts to Instagram as a feed post with the AI-generated caption Updates the Google Sheet row with the prompt, caption, image URL, and status "Posted" 🛠 Tools & Services Used | Tool | Purpose | |---|---| | AlekSystem Schedule Trigger | Fires the workflow daily at 13:10 | | Google Sheets | Stores content ideas and tracks post status | | OpenAI GPT-4.1 Nano | Generates image prompts and Instagram captions | | Google Gemini 2.5 Flash Image | Generates the AI image from the prompt | | UploadToURL | Hosts the image on a public CDN | | Instagram Graph API | Publishes the image as a feed post | 📋 Google Sheet Structure Your sheet (Instagram Posting) needs these columns: | Column | Description | |---|---| | Idea/Niche | The content topic (e.g. Minimalist Home, Luxury Cars) | | Status | Set to Ready to queue a post; auto-updated to Posted | | Prompt | Auto-filled with the AI-generated image prompt | | Caption | Auto-filled with the AI-generated Instagram caption | | Image_URL | Auto-filled with the CDN-hosted image link | ⚙️ Setup Requirements Google Sheets OAuth2** credentials connected to your spreadsheet OpenAI API** key (GPT-4.1 Nano) Google Gemini (PaLM) API** key UploadToURL** account and API credentials Instagram Graph API** credentials (connected Business/Creator account) 💡 How to Use Add your content ideas to the Google Sheet with Status = "Ready" Import this workflow into your AlekSystem instance Connect all credentials Activate the workflow — it will auto-post daily at 1:10 PM IST
