Telegram to TikTok & Reels: Claude + Postdom n8n Workflow

Send a video in Telegram—get auto captions and scheduled publishing to TikTok & Reels (with Claude approval)

This Telegram to TikTok & Reels: Claude + Postdom n8n Workflow listens for your video messages in Telegram, generates platform-specific captions using Anthropic Claude, requests your approval in Telegram, then uploads and publishes to TikTok, Instagram Reels, and YouTube Shorts via Postdom.

What this workflow does

• Triggers when your Telegram bot receives a new message and loads your configured `owner user ID` and selected target platforms.
• Accepts only messages from your Telegram user ID and only MP4/MOV videos up to 20 MB (responds with instructions to everyone else).
• Fetches your Postdom brand brief and prompts Anthropic Claude to generate:
  • One caption per selected platform
  • A YouTube title
  as structured JSON.
• Cleans and trims each caption to each platform’s character limits, then sends a preview back to Telegram for approval, waiting up to 24 hours.
• When approved, downloads the video from Telegram, reads width/height/duration, uploads it to Postdom storage, and publishes one post per platform with your caption and settings (privacy/visibility and optional scheduling).
• Posts back in Telegram with the publish status for each platform, including guidance when publishing requires approval or when an upload/publish error occurs.

Use cases

• Solo creators: send raw clips to Telegram and approve AI captions before publishing.
• SaaS operators: keep TikTok/Reels/Shorts workflows consistent using a Postdom brand brief + Claude.
• Automation engineers: streamline multi-platform posting with a single Telegram intake point.
