YouTube-Specific Features

🎬

Video Uploads

Upload videos directly via the CLI. Supports all major formats including MP4, MOV, AVI, MKV, and WEBM.

👁

Visibility Control

Set videos to public, unlisted, or private. Control who can discover and watch your content from the start.

🧒

Kids Content

Add tags to improve discoverability. Each tag has a value and label for flexible categorization and SEO.

📅

Scheduled Publishing

Schedule video uploads with precise timestamps. Videos are uploaded and set to publish at your chosen time.

How It Works

Find Your YouTube Integration

List your connected accounts and grab your YouTube integration ID. You can also fetch available settings to see what options are supported.

Discovery

# List all integrations
postiz integrations:list

# Filter for YouTube
postiz integrations:list | jq \
  '.[] | select(.identifier=="youtube")'

# Get YouTube settings schema
postiz integrations:settings <youtube-id>

Upload Your Video & Thumbnail

Upload your video file and optionally a custom thumbnail. YouTube requires media to be accessible via HTTPS. Supports MP4, MOV, AVI, MKV, WEBM, and more.

Upload

# Upload video and extract URL
RESULT=$(postiz upload video.mp4)
VIDEO_URL=$(echo "$RESULT" | jq -r '.path')

# Upload custom thumbnail
THUMB=$(postiz upload thumbnail.jpg)
THUMB_ID=$(echo "$THUMB" | jq -r '.id')
THUMB_PATH=$(echo "$THUMB" | jq -r '.path')

echo $VIDEO_URL
# https://uploads.postiz.com/your-video.mp4

Create Your Post

Schedule a YouTube upload with your video, description, title, visibility settings, tags, and optional thumbnail.

What is Codex?

Codex is OpenAI's autonomous coding agent that handles software engineering tasks — writing features, fixing bugs, and answering questions about your codebase. It works via CLI and IDE integrations, and can execute shell commands like Postiz.

💻

CLI & IDE Native

Codex runs from your terminal or IDE. It executes shell commands directly, making Postiz integration seamless — no extra configuration needed.

🔧

Autonomous Execution

Codex works in sandboxed cloud environments, autonomously running commands, reading output, and chaining multi-step workflows like social media posting.

⚡

Parallel Tasks

Run multiple Codex tasks simultaneously. Schedule posts to different platforms in parallel while Codex handles other coding work.

How Postiz Works with Codex

Codex discovers Postiz when you install it globally. It reads the SKILL.md to understand available commands and can autonomously chain them for social media workflows.

✓Install Postiz Agent globally with npx skills add
✓Codex reads the SKILL.md and learns all Postiz commands
✓POSTIZ_API_KEY must be set in environment
✓Codex executes commands in sandboxed environments
✓Works alongside your coding tasks in parallel

Install Postiz

# Install the Postiz skill
npx skills add gitroomhq/postiz-agent

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Codex discovers Postiz commands
# from the SKILL.md automatically
codex "list my social media integrations"

YouTube Uploading with Codex

Tell Codex what to post from your terminal or IDE — it discovers your integrations via Postiz and handles the entire publishing workflow.

💻

CLI Workflow

Terminal and IDE integration

Tell Codex what to post from your terminal or IDE — it discovers your integrations via Postiz and handles the entire publishing workflow.

Codex CLI

$ codex "Post to Youtube about our
  new feature launch, schedule for
  tomorrow at 9am"

Codex: I'll handle that.
  Running: postiz integrations:list
  Found your Youtube integration.
  Running: postiz posts:create ...

  Done! Your post is scheduled.
  Post ID: abc-123

💻

Parallel Tasks

Multiple tasks at once

Codex can handle multiple tasks in parallel. Schedule posts to different platforms while it works on other coding tasks simultaneously.

Codex Parallel Tasks

# Run multiple posting tasks in parallel
$ codex "Schedule a post about our
  launch to X for tomorrow 9am" &

$ codex "Write a LinkedIn article
  about our new feature and schedule
  for tomorrow noon" &

$ codex "Fix the bug in auth.ts"

# All three tasks run simultaneously

Why Codex + Postiz for YouTube

Codex's autonomous execution makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for YouTube workflows.

✓CLI-native — runs from your terminal or IDE
✓Autonomous execution in sandboxed environments
✓Parallel task support — post while coding
✓Thumbnails and tags applied automatically based on your instructions
✓Cross-post to YouTube + other platforms in a single session
✓Powered by OpenAI's most capable models

Also Works with Claude Code

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including Anthropic's Claude Code.

Claude Code

by Anthropic

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your YouTube integration, uploads your video and thumbnail, applies tags and visibility settings, and schedules the upload.

Claude Code

> Upload my tutorial video to YouTube
  as public with tags "coding" and
  "tutorial", schedule for tomorrow

Claude will automatically run:
  postiz integrations:list
  postiz upload ./tutorial.mp4
  postiz upload ./thumbnail.jpg
  postiz posts:create \
    -c "Full tutorial description" \
    -m "uploaded-video-url" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"title":
      "My Tutorial Video",
      "type":"public",
      "selfDeclaredMadeForKids":"no",
      "tags":[{"value":"coding",
        "label":"Coding"},
        {"value":"tutorial",
        "label":"Tutorial"}]}' \
    -i "youtube-id"

YouTube + Other Platforms

Schedule the same video to YouTube and other platforms in a single command. Each platform gets its own settings.

Terminal

# Post a video to YouTube and TikTok simultaneously
postiz posts:create \
  -c "New tutorial is live! #coding #tutorial" \
  -m "$VIDEO_URL" \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "title": "Build a REST API in 10 Minutes",
    "type": "public",
    "selfDeclaredMadeForKids": "no",
    "tags": [
      {"value": "tutorial", "label": "Tutorial"},
      {"value": "api", "label": "API"}
    ]
  }' \
  -i "youtube-id,tiktok-id"

# Batch schedule a week of YouTube uploads
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "Episode $day of our coding series" \
    -m "episode${day}-video-url" \
    -s "2025-03-0${day}T15:00:00Z" \
    --settings '{"title":"Coding Series Ep '$day'","type":"public","selfDeclaredMadeForKids":"no"}' \
