Post to Instagram in Seconds

Terminal

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

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Find your Instagram integration
postiz integrations:list

# Upload an image
RESULT=$(postiz upload photo.jpg)

Instagram-Specific Features

📷

Feed Posts

Publish photo and video posts to your Instagram feed with captions, hashtags, and location tags. Schedule for optimal engagement times.

📱

Stories

Share ephemeral content with Instagram Stories. Upload images or videos that disappear after 24 hours.

🎬

Trial Reels

Test content with trial reels that have limited initial reach. Graduate to full distribution manually or automatically based on performance.

🤝

Collaborator Tags

Tag collaborators on your posts to co-author content. The post appears on both profiles, doubling your reach.

📊

Graduation Strategy

Control how trial reels graduate to full reach. Choose MANUAL for hands-on control or SS_PERFORMANCE for automatic promotion.

📅

Scheduled Posting

Schedule posts and stories with precise timestamps. Plan your Instagram content calendar and let Postiz handle the publishing.

How It Works

Find Your Instagram Integration

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

Discovery

# List all integrations
postiz integrations:list

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

# Get Instagram settings schema
postiz integrations:settings <instagram-id>

Upload Your Media

Upload your photo or video to get a public URL. Instagram requires media to be accessible via HTTPS. Supports JPG, PNG, MP4, and more.

Upload

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

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

Create Your Post

Schedule an Instagram post with your media, caption, hashtags, and platform-specific settings like post type, trial reels, and collaborators.

Post Creation

postiz posts:create \
  -c "Sunset vibes #photography #nature" \
  -m "$IMAGE_URL" \
  -s "2025-03-01T18:00:00Z" \
  --settings '{
    "post_type": "post",
    "collaborators": [
      {"label": "photographer_friend"}
    ]
  }' \
  -i "instagram-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"

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

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

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 Instagram workflows.

✓CLI-native — runs from your terminal or IDE
✓Autonomous execution in sandboxed environments
✓Parallel task support — post while coding
✓Trial reels and graduation strategies applied automatically
✓Cross-post to Instagram + 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 Instagram integration, uploads your photo, applies post type and collaborator settings, and schedules the post.

Claude Code

> Post my product photo to Instagram
  as a feed post with collaborator tags,
  schedule for tomorrow evening

Claude will automatically run:
  postiz integrations:list
  postiz upload ./product.jpg
  postiz posts:create \
    -c "Launching something new!" \
    -m "uploaded-url" \
    -s "2025-03-02T18:00:00Z" \
    --settings '{"post_type":"post",
      "collaborators":[
        {"label":"cofounder"}
      ]}' \
    -i "instagram-id"

Instagram + Other Platforms

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

Terminal

# Post to Instagram and Facebook simultaneously
postiz posts:create \
  -c "New product photo! #launch #startup" \
  -m "$IMAGE_URL" \
  -s "2025-03-01T18:00:00Z" \
  --settings '{"post_type":"post"}' \
  -i "instagram-id,facebook-id"

# Batch schedule a week of Instagram content
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "Day $day of our launch week! #countdown" \
    -m "day${day}-image-url" \
    -s "2025-03-0${day}T18:00:00Z" \
    --settings '{"post_type":"post"}' \
    -i "instagram-id"
done
