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

Setup

Required: Set your Postiz API key

export POSTIZ_API_KEY=your_api_key_here

Optional: Custom API endpoint

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

Commands

Discovery & Settings

List all connected integrations

postiz integrations:list

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"}'

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>

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"

FLAIR_ID=$(echo "$FLAIRS" | jq -r '.output[0].id')
