This skill is a CLI wrapper for the official Postiz social media scheduling API. It requires a POSTIZ_API_KEY environment variable for authentication and makes HTTPS requests to api.postiz.com (or a custom API URL). It can read local files from disk for media uploads. No shell command execution, no filesystem writes, and only two well-known runtime dependencies (node-fetch, yargs).
Postiz Social Scheduler

CLI tool for scheduling social media posts across 28+ platforms including X, LinkedIn, Reddit, YouTube, TikTok, and Instagram. Manage integrations, upload media, and track analytics from your terminal.

Important Notes
- Always upload media to Postiz before posting (platforms like TikTok and Instagram reject external URLs)
- Date parameter is required for all posts (ISO 8601 format)
- Use
integrations:settingsto discover character limits and required fields - Use JSON mode for complex multi-platform campaigns with different content per platform
- If analytics returns
{"missing": true}, resolve withposts:missing+posts:connect
Best Practices
- Always upload media files to Postiz before posting, as platforms like TikTok and Instagram reject external URLs
- Use integrations:settings to discover character limits and required fields before creating posts
- Schedule posts in ISO 8601 date format with timezone to ensure accurate timing
- Use JSON mode for complex multi-platform campaigns with different content per platform
- Check analytics regularly and resolve missing release IDs with posts:missing and posts:connect
Avoid
- Don't post with external media URLs directly, as many platforms will reject them. Always use postiz upload first.
- Don't hardcode integration IDs. Use integrations:list to discover current IDs as they may change.
- Don't skip the date parameter. Scheduling date is required for all posts.
- Don't ignore missing release IDs in analytics. Posts without a connected release ID won't show analytics data.
