How It Works

Find Your Facebook Integration

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

Discovery

# List all integrations
postiz integrations:list

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

# Get Facebook settings schema
postiz integrations:settings <facebook-id>

Prepare Your Content

Write your post content and optionally upload media. For link posts, just include the URL in settings — Facebook generates the preview automatically.

Prepare

# Upload an image (optional)
RESULT=$(postiz upload photo.jpg)
IMAGE_URL=$(echo "$RESULT" | jq -r '.path')

echo $IMAGE_URL
# https://uploads.postiz.com/photo.jpg

# Or just use a link URL in settings
# for rich link previews

Create Your Post

Schedule a Facebook post with your content, optional media, and platform-specific settings like link URL for rich previews.

Post Creation

postiz posts:create \
  -c "We just launched our new feature!" \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "url": "https://example.com/launch"

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"

Facebook Posting 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 Facebook about our
  new feature launch, schedule for
  tomorrow at 9am"

Codex: I'll handle that.
  Running: postiz integrations:list
  Found your Facebook 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 Facebook

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 Facebook workflows.

✓CLI-native — runs from your terminal or IDE
✓Autonomous execution in sandboxed environments
✓Parallel task support — post while coding
✓Link previews generated automatically when a URL is provided
✓Cross-post to Facebook + 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 Facebook integration, composes your post with a link preview if needed, and schedules the post.

Claude Code

> Share our new blog post on Facebook
  with a link preview, schedule for
  tomorrow morning

Claude will automatically run:
  postiz integrations:list
  postiz posts:create \
    -c "New on our blog: How to..." \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"url":
      "https://example.com/blog/
      how-to-automate"}' \
    -i "facebook-id"

Facebook + Other Platforms

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

Terminal

# Post to Facebook and Instagram simultaneously
postiz posts:create \
  -c "Big announcement! Check out our latest update." \
  -m "$IMAGE_URL" \
  -s "2025-03-01T10:00:00Z" \
  --settings '{"url":"https://example.com/update"}' \
  -i "facebook-id,instagram-id"

# Batch schedule a week of Facebook content
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "Day $day tip for growing your business!" \
    -s "2025-03-0${day}T10:00:00Z" \
    --settings '{}' \
    -i "facebook-id"
done
