|Overview |Sample| |-|-| |This template is the first of its kind: it automatically generates both the caption and the image for your Instagram posts by analysing your existing feed, with zero spreadsheets or manual steps. Once configured, the workflow runs on a schedule, fetches your past posts, and uses a custom AI agent to craft a new caption and image prompt. Then creates the image via OpenRouter (Nano Banana) and stores everything in Airtable. A Telegram message gives you one‑tap control to confirm, regenerate or cancel; if confirmed, the post is published directly to Instagram. Perfect for creators and marketers who want fresh, on‑brand content without daily manual effort. | | Good to Know Fully hands‑off:** No need to prepare datasets or manually upload assets. The workflow reads your Instagram history via the Graph API and generate new content. AI‑powered creativity:** Uses OpenAI for caption generation and Nano Banana via OpenRouter for image synthesis. Privacy‑friendly:** Your content stays within your Airtable and n8n instance; only the AI models receive anonymised prompts. Nano Banana:** Currently the gemini-2.5-flash-image-preview model is used but you can use any available in Open Route. How It Works Scheduling: A schedule trigger initiates the workflow at your chosen time. Feed Analysis: The workflow uses your Instagram business account ID and access token to fetch past posts. AI Content Generation: A custom AI agent analyses your captions, applies category tag, and writes a new caption and a detailed image prompt. If there is no content it will be based on the category to create something new. Image Creation: The prompt is sent to the Nano Banana model on OpenRouter to generate a new image. The binary is converted to JPEG and stored in Airtable wih the caption and prompt. Approval via Telegram: A Telegram bot sends you the generated image, caption and three inline buttons: Confirm, Regenerate and Cancel. ✅ Confirm: Uploads the image to Instagram via a Graph API call. ♻️ Regenerate: Re‑runs just the AI creation steps, generating a different title and image. ❌ Cancel: Updates the Telegram message to note the cancellation and removes the buttons. Publishing: When confirmed, the workflow uses the image’s public URL (generated in Airtable and served via an n8n webhook) to create and publish the post on Instagram. How to Use Prepare your accounts: Instagram Business Account connected to a Facebook Page (get your IG Business ID and a long‑lived Graph API access token). Airtable base and table with fields: id, img_prompt, caption, data_binary, action, mime_type, created_at. Personal access token for Airtable, Telegram bot token and chat ID, OpenAI and OpenRouter API keys. Create workflows: Four workflows are included: schedule trigger, webhook to serve the image, main content‑generation workflow and Telegram response workflow. Replace placeholders: Fill in your account IDs, token values, n8n instance URL and webhook paths. Define Category: Adjust the Define Category node to steer the content theme (e.g. natural landscapes, urban fashion). Activate and test: Activate the workflows "ebhook to serve the image and Telegram response workflow. Configure Schedule Trigger workflow to call the Main Content-Generation Workflow. Run the Main Content-Generation Workflow once to create a sample post and test the Telegram buttons. Activate the schedule for the generation of automatic posts. Requirements Instagram Business account & Facebook Graph API (tokens with instagram_basic and instagram_content_publish permissions) Airtable base & personal access token Telegram bot (token & chat ID) OpenAI API key OpenRouter API key Customization Caption tone:** Modify the AI Agent prompt to change tone (flirtatious, motivational, mysterious).
