How it works
How it works This workflow turns any URL sent to a Telegram bot into ready-to-publish social posts: Trigger: Telegram message (checks if it contains a URL). Fetch & parse: Downloads the page and extracts readable text + title. AI writing: Generates platform-specific copy (Facebook, Instagram, LinkedIn). Image: Creates an AI image and stores it in Supabase Storage. Publish: Posts to Facebook Pages, Instagram Business, LinkedIn. Logging: Updates Google Sheets with post URLs and sends a Telegram confirmation (image + links). Setup Telegram – create a bot, connect via n8n Telegram credentials. OpenAI / Gemini – add API key in n8n Credentials and select it in the AI nodes. 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) LinkedIn – connect with OAuth2 in the LinkedIn node (leave as credential). Supabase – credential supabase with url and apiKey. Ensure a bucket exists (default used in the Set node is social-media). Google Sheets – replace YOUR_GOOGLE_SHEET_ID and Sheet1. Grant your n8n Google OAuth2 access. Notes • 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. Required credentials • Telegram Bot • OpenAI (or Gemini) • Facebook/Instagram Graph • LinkedIn OAuth2 • Supabase (url + apiKey) • Google Sheets OAuth2 Inputs • A Telegram message that contains a URL. Outputs • Social posts published on Facebook, Instagram, LinkedIn. • Row appended/updated in Google Sheets with post URLs and image link. • Telegram confirmation with the generated image + post links.
