Postiz CLI

Social media automation CLI for AI agents - Schedule posts across 28+ platforms programmatically.

The Postiz CLI provides a command-line interface to the Postiz API, enabling developers and AI agents to automate social media posting, manage content, and handle media uploads across platforms like Twitter/X, LinkedIn, Reddit, YouTube, TikTok, Instagram, Facebook, and more.

Installation

From npm (Recommended)

npm install -g postiz
# or
pnpm install -g postiz

---

Authentication

Option 1: OAuth2 (Recommended)

Authenticate using the device flow — no client ID or secret needed:

postiz auth:login

This will:

1. Display a one-time code in your terminal
2. Open your browser to authorize
3. Automatically save credentials to ~/.postiz/credentials.json

# Check current auth status (verifies credentials are still valid)
postiz auth:status

# Remove stored credentials
postiz auth:logout

Self-Hosting the Auth Server

By default, postiz auth:login uses the hosted auth server at cli-auth.postiz.com. If you want to self-host the OAuth2 device flow server, follow the guide in server/SERVER.md.

Option 2: API Key

export POSTIZ_API_KEY=your_api_key_here

Optional: Custom API endpoint

export POSTIZ_API_URL=https://your-custom-api.com

Note: OAuth2 credentials take priority over the API key when both are present.
