"content": "## Turn one video into native TikTok, Instagram and YouTube posts\n\n### Who's it for\nCreators, solo founders and small agencies who publish the same video to several networks and are tired of rewriting the caption three times \u2014 or of pasting the identical text everywhere and watching it underperform.\n\n### What it does\nYou give it one idea and one video URL. PostWire's Smart Distribute writes a **native caption for each network** \u2014 the right length, hashtags, SEO and format per platform \u2014 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.",
