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.

Managing Posts

List posts

postiz posts:list
postiz posts:list --startDate "2024-01-01T00:00:00Z" --endDate "2024-12-31T23:59:59Z"
postiz posts:list --customer "customer-id"

Defaults to last 30 days to next 30 days if dates not specified.

Delete post

postiz posts:delete <post-id>

Change post status (draft ↔ schedule)

postiz posts:status <post-id> --status draft
postiz posts:status <post-id> --status schedule

Move a scheduled post back to a draft, or promote a draft into the publishing queue. Switching to draft also terminates any workflow that's already running for the post, so it won't publish. Switching to schedule queues the post for publishing at its stored date.
