WordPress-Specific Features

📝

Posts & Pages

🖼

Featured Images

Upload and set featured images for your posts and pages. Eye-catching thumbnails drive more clicks from your site.

📄

Content Management

Manage your WordPress content programmatically. Create, schedule, and organize posts without touching the admin panel.

📅

Scheduled Publishing

🤖

AI-Powered Workflows

Let AI agents draft, format, and publish your WordPress content. From idea to published post without manual intervention.

🔄

Multi-Site Support

Connect multiple WordPress sites and publish to any of them. Manage all your sites from a single Postiz account.

How It Works

Find Your WordPress Integration

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

Discovery

# List all integrations
postiz integrations:list

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

# Get WordPress settings schema
postiz integrations:settings <wordpress-id>

Prepare Your Content

Write your content and optionally upload a featured image. WordPress supports HTML content for rich formatting.

Upload

# Upload a featured image (optional)
RESULT=$(postiz upload featured.jpg)
IMAGE_PATH=$(echo "$RESULT" | jq -r '.path')
IMAGE_ID=$(echo "$RESULT" | jq -r '.id')

echo "Featured: $IMAGE_PATH"
# https://uploads.postiz.com/featured.jpg

Create Your Post

Create a WordPress post or page with your content, title, featured image, and content type settings.

Publish

postiz posts:create \
  -c "Post content..." \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "title": "10 Tips for Better Code Reviews",
    "main_image": {
      "id": "img-id",
      "path": "https://uploads.postiz.com/featured.jpg"
    },
    "type": "post"
  }' \
  -i "wordpress-id"

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"

WordPress Publishing 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 Wordpress about our
  new feature launch, schedule for
  tomorrow at 9am"

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

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 WordPress workflows.

✓CLI-native — runs from your terminal or IDE
✓Autonomous execution in sandboxed environments
✓Parallel task support — post while coding
✓Featured images uploaded and attached automatically
✓Cross-post to WordPress + 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 WordPress integration, uploads your featured image, sets the content type, and publishes the post.

Claude Code

> Publish my code review tips article
  to WordPress as a blog post with
  a featured image

Claude will automatically run:
  postiz integrations:list
  postiz upload ./featured.jpg
  postiz posts:create \
    -c "$(cat code-review-tips.md)" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"title":
      "10 Tips for Better Code Reviews",
      "main_image":{"id":"...",
        "path":"uploaded-url"},
      "type":"post"}' \
    -i "wordpress-id"

WordPress + Other Platforms

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

Terminal

# Cross-post an article to WordPress and Medium
postiz posts:create \
  -c "$(cat article.md)" \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "title": "Building Scalable APIs",
    "main_image": {
      "id": "img-id",
      "path": "https://uploads.postiz.com/api-cover.jpg"
    },
    "type": "post"
  }' \
  -i "wordpress-id,medium-id"

# Batch schedule a week of WordPress posts
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "$(cat posts/day${day}.md)" \
    -s "2025-03-0${day}T08:00:00Z" \
    --settings '{"title":"Day '"$day"' Tips","type":"post"}' \
    -i "wordpress-id"
done
