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:

This will:

Display a one-time code in your terminal
Open your browser to authorize
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.

Commands

Discovery & Settings

List all connected integrations

Returns integration IDs, provider names, and metadata.

Get integration settings schema

postiz integrations:settings <integration-id>

Returns character limits, required settings, and available tools for fetching dynamic data.

Trigger integration tools

postiz integrations:trigger <integration-id> <method-name>
postiz integrations:trigger <integration-id> <method-name> -d '{"key":"value"}'

Fetch dynamic data like Reddit flairs, YouTube playlists, LinkedIn companies, etc.

Examples:

# Get Reddit flairs
postiz integrations:trigger reddit-123 getFlairs -d '{"subreddit":"programming"}'

# Get YouTube playlists
postiz integrations:trigger youtube-456 getPlaylists

# Get LinkedIn companies
postiz integrations:trigger linkedin-789 getCompanies

Creating Posts

Simple scheduled post

postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -i "integration-id"

Draft post

postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -t draft -i "integration-id"

Post with media

postiz posts:create -c "Content" -m "img1.jpg,img2.jpg" -s "2024-12-31T12:00:00Z" -i "integration-id"

Post with comments (each comment can have its own media)

postiz posts:create \
  -c "Main post" -m "main.jpg" \
  -c "First comment" -m "comment1.jpg" \
  -c "Second comment" -m "comment2.jpg,comment3.jpg" \
  -s "2024-12-31T12:00:00Z" \
  -i "integration-id"

Multi-platform post

postiz posts:create -c "Content" -s "2024-12-31T12:00:00Z" -i "twitter-id,linkedin-id,facebook-id"

Platform-specific settings

postiz posts:create \
  -c "Content" \
  -s "2024-12-31T12:00:00Z" \
  --settings '{"subreddit":[{"value":{"subreddit":"programming","title":"Post Title","type":"text"}}]}' \
  -i "reddit-id"

Complex post from JSON file

postiz posts:create --json post.json

Options:

-c, --content - Post/comment content (use multiple times for posts with comments)
-s, --date - Schedule date in ISO 8601 format (REQUIRED)
-t, --type - Post type: "schedule" or "draft" (default: "schedule")
-m, --media - Comma-separated media URLs for corresponding -c
-i, --integrations - Comma-separated integration IDs (required)
-d, --delay - Delay between comments in minutes (default: 0)
--settings - Platform-specific settings as JSON string
-j, --json - Path to JSON file with full post structure
--shortLink - Use short links (default: true)

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.

Analytics

Get platform analytics

postiz analytics:platform <integration-id>
postiz analytics:platform <integration-id> -d 30

Returns metrics like followers, impressions, and engagement over time for a specific integration/channel. The -d flag specifies the number of days to look back (default: 7).

Get post analytics

postiz analytics:post <post-id>
postiz analytics:post <post-id> -d 30

Returns metrics like likes, comments, shares, and impressions for a specific published post.

⚠️ If analytics:post returns {"missing": true}, the post was published but the platform didn't return a usable post ID. You must resolve this before analytics will work:

# 1. List available content from the provider
postiz posts:missing <post-id>

# 2. Connect the correct content to the post
postiz posts:connect <post-id> --release-id "7321456789012345678"

# 3. Analytics will now work
postiz analytics:post <post-id>

Connecting Missing Posts

Some platforms (e.g. TikTok) don't return a post ID immediately after publishing. The post's releaseId is set to "missing" and analytics won't work until resolved.

List available content from the provider

postiz posts:missing <post-id>

Returns an array of {id, url} items representing recent content from the provider. Returns an empty array if the provider doesn't support this feature.

Connect a post to its published content

postiz posts:connect <post-id> --release-id "<content-id>"

Media Upload

Upload file and get URL

postiz upload <file-path>

⚠️ IMPORTANT: Upload Files Before Posting

You must upload media files to Postiz before using them in posts. Many platforms (especially TikTok, Instagram, and YouTube) require verified/trusted URLs and will reject external links.

Workflow:

Upload your file using postiz upload
Extract the returned URL
Use that URL in your post's -m parameter

Supported formats:

Images: PNG, JPG, JPEG, GIF
Videos: MP4

Example:

# 1. Upload the file first
RESULT=$(postiz upload video.mp4)
PATH=$(echo "$RESULT" | jq -r '.path')

# 2. Use the Postiz URL in your post
postiz posts:create -c "Check out my video!" -s "2024-12-31T12:00:00Z" -m "$PATH" -i "tiktok-id"

Why this is required:

TikTok, Instagram, YouTube only accept URLs from trusted domains
Security: Platforms verify media sources to prevent abuse
Reliability: Postiz ensures your media is always accessible

Features for AI Agents

Discovery Workflow

The CLI enables dynamic discovery of integration capabilities:

List integrations - Get available social media accounts
Get settings - Retrieve character limits, required fields, and available tools
Trigger tools - Fetch dynamic data (flairs, playlists, boards, etc.)
Create posts - Use discovered data in posts
Analyze - Get post analytics; if {"missing": true} is returned, resolve with posts:missing + posts:connect

This allows AI agents to adapt to different platforms without hardcoded knowledge.

JSON Mode

For complex posts with multiple platforms and settings:

postiz posts:create --json complex-post.json

JSON structure:

{
  "integrations": ["twitter-123", "linkedin-456"],
  "posts": [
    {
      "provider": "twitter",
      "post": [
        {
          "content": "Tweet version",
          "image": ["twitter-image.jpg"]
        }
      ]
    },
    {
      "provider": "linkedin",
      "post": [
        {
          "content": "LinkedIn version with more context...",
          "image": ["linkedin-image.jpg"]
        }
      ],
      "settings": {
        "__type": "linkedin",
        "companyId": "company-123"
      }
    }
  ]
}

All Output is JSON

Every command outputs JSON for easy parsing:

INTEGRATIONS=$(postiz integrations:list | jq -r '.')
REDDIT_ID=$(echo "$INTEGRATIONS" | jq -r '.[] | select(.identifier=="reddit") | .id')

Threading Support

Comments are automatically converted to threads/replies based on platform:

Twitter/X: Thread of tweets
Reddit: Comment replies
LinkedIn: Comment on post
Instagram: First comment

postiz posts:create \
  -c "Main post" \
  -c "Comment 1" \
  -c "Comment 2" \
  -i "integration-id"
