Turn one video into native TikTok, Instagram and YouTube posts with PostWire

## Turn one video into native TikTok, Instagram and YouTube posts ### Who's it for Creators, solo founders and small agencies who publish the same video to several networks and are tired of rewriting the caption three times — or of pasting the identical text everywhere and watching it underperform. ### What it does You give it one idea and one video URL. 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. ### How to set up 1. 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. 2. Copy your API key from the dashboard. 3. In n8n, create a Header Auth credential: name Authorization, value Bearer pw_live_your_key. 4. Select that credential on both HTTP Request nodes. 5. Edit the Your idea, video and platforms node with your own idea, video URL and networks. ### Requirements - A PostWire API key (free tier works). - A publicly reachable video URL (MP4). TikTok and YouTube reject text-only or photo posts. ### How to customize - Change platforms to any mix of the supported networks. - Swap the manual trigger for a Schedule, RSS or Google Sheets trigger to run it unattended. - To queue a post for later instead of publishing now, call POST /api/schedule with a run_at timestamp. - brand_voice is free text and steers every caption at once.
