How to Upload a Video to Multiple Social Media Sites

Four steps: connect your accounts via each platform's official OAuth, upload one vertical MP4, set your title and captions, publish or schedule. Every upload goes through the YouTube Data API, TikTok Content Posting API, Instagram Graph API, and Facebook's video endpoints — original file, no re-encoding.
