This workflow turns any URL sent to a Telegram bot into ready-to-publish social posts:
1. Trigger: Telegram message (checks if it contains a URL).
2. Fetch & parse: Downloads the page and extracts readable text + title.
3. AI writing: Generates platform-specific copy (Facebook, Instagram, LinkedIn).
4. Image: Creates an AI image and stores it in Supabase Storage.
5. Publish: Posts to Facebook Pages, Instagram Business, LinkedIn.
6. Logging: Updates Google Sheets with post URLs and sends a Telegram confirmation (image + links).
1. Telegram – create a bot, connect via n8n Telegram credentials.
2. OpenAI / Gemini – add API key in n8n Credentials and select it in the AI nodes.
3. Facebook/Instagram (Graph API) – create a credential called facebookGraph with:
• accessToken (page-scoped or system user)
• pageId (for Facebook Page photos)
• igUserId (Instagram Business account ID)
• optional fbApiVersion (default v19.0)
4. LinkedIn – connect with OAuth2 in the LinkedIn node (leave as credential).
5. Supabase – credential supabase with url and apiKey. Ensure a bucket exists (default used in the Set node is social-media).
6. Google Sheets – replace YOUR_GOOGLE_SHEET_ID and Sheet1. Grant your n8n Google OAuth2 access.
• No API keys are stored in the template. Everything runs via n8n Credentials.
• You can change bucket name, image size/quality, and AI prompts in the respective nodes.
• The confirmation message on Telegram includes direct permalinks to the published posts.
