  --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)

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>

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

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')
