# Post Telegram videos to TikTok, Instagram and YouTube with Claude and Postdom

> Quick overview This workflow listens for videos sent to your Telegram bot, uses Anthropic Claude to generate platform-specific captions based on your notes and a Postdom brand brief, requests approval in Telegram, then uploads and publishes the video to TikTok, Instagram Reels, and YouTube Shorts via Postdom. How it works 1. Triggers when a new Telegram message is received by your bot and loads your configured owner user ID and target platforms. 2. Accepts only messages from your Telegram user ID and only MP4/MOV videos up to 20 MB, replying with instructions to everyone else. 3. Fetches your brand brief from Postdom and prompts Anthropic Claude to generate one caption per selected platform (plus a YouTube title) as structured JSON. 4. Cleans and trims captions to each platform’s character limits and sends a preview back to Telegram for approval, waiting up to 24 hours. 5. If approved, downloads the video from Telegram, reads its width/height/duration, and uploads it to Postdom storage
