PostWire's Smart Distribute writes a **native caption for each network** — the right length, hashtags, SEO and format per platform — and then publishes the video to every connected account in a single call. TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Bluesky, Mastodon, Telegram, Discord and Reddit are supported.\n\n### How to set up\n1. Create a free PostWire account at https://postwire.io/dashboard.html (1 brand, 30 posts/month, no card) and connect your social accounts there with OAuth.\n2. Copy your API key from the dashboard.\n3. In n8n, create a **Header Auth** credential: name `Authorization`, value `Bearer pw_live_your_key`.\n4. Select that credential on both HTTP Request nodes.\n5. Edit the **Your idea, video and platforms** node with your own idea, video URL and networks.\n\n### Requirements\n- A PostWire API key (free tier works).\n- A publicly reachable video URL (MP4). TikTok and YouTube reject text-only or photo posts.\n\n### How to customize\n- Change `platforms` to any mix of the supported networks.\n- Swap the manual trigger for a Schedule, RSS or Google Sheets trigger to run it unattended.\n- To queue a post for later instead of publishing now, call `POST /api/schedule` with a `run_at` timestamp.\n- `brand_voice` is free text and steers every caption at once."
