How does Grok Bot post to Facebook?

Find Your Facebook Integration

Ask Grok Bot whether your Facebook account is connected. It also checks which options the platform supports.

Grok Bot: Yes — your Facebook account is connected
  and ready. Want me to post something?
2

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.

  feature launch

Grok Bot: Here's a draft for Facebook:
  "We just shipped something big..."
  Want me to add media and schedule it?
3

What is Grok Bot?

Grok Bot is the always-on AI teammate product from xAI and Cursor. You create named Bots, give each one a job, and they work 24/7 on their own persistent cloud computer — with a browser, a filesystem, and a terminal — pinging you only when they need approval.

Grok Bot is not the Grok chatbot. Grok is the assistant you chat with on X and grok.com. Grok Bot is a separate app for delegating real, multi-step work — like running your Facebook presence with Postiz.

💻

Own Cloud Computer

Every Bot gets a persistent cloud machine with a terminal. Postiz runs there, so your Facebook posts go out even when your laptop is closed.

🔁

Routines

Turn any task into a routine that runs on a schedule. Your Bot drafts, schedules, and reports on Facebook content without being asked twice.

🛡️

Approvals Built In

Bots ask before changing external systems. Review the Facebook posts your Bot prepared in Postiz, approve, and it publishes.

How Postiz Works with Grok Bot

Postiz is listed on the Grok Bot plugin marketplace. Add it to a Bot and the Postiz skill, CLI, and command reference are installed on its cloud computer — the Bot can then manage your Facebook workflow on its own.

  • ✓Type /add-plugin postiz in a Bot chat, or add it from the Plugins sidebar
  • ✓Store your POSTIZ_API_KEY as a Bot secret when prompted
  • ✓The Bot reads the bundled SKILL.md and learns every Postiz command
  • ✓Works in every Bot on your shared workspace, on desktop and iPhone
  • ✓Approvals keep a human in the loop before anything is published

Grok Bot

# 1. Add the plugin to your Bot
/add-plugin postiz

# 2. Store your Postiz API key
#    as a secret when prompted

# 3. Ask your Bot to verify
You: Find my Facebook channel in Postiz

How Grok Bot runs Facebook on a routine

Your Bot reads the Postiz skill, discovers your Facebook integration, and handles the entire posting workflow — from content creation to scheduling — on its own cloud computer.

🧠

Message Your Bot

Desktop, iPhone, or a group chat

Send a message to your Bot from the desktop app or your iPhone. It runs on its own cloud computer, so it picks up your message, discovers your Facebook account via Postiz, uploads your media, and schedules the post — then asks you to approve before it goes live.

Grok Bot

You: Post to Facebook about our new
  feature launch, schedule for tomorrow
  at 9am

Bot: Got it! Here's the plan:
  1. Find your Facebook integration
  2. Compose your post content
  3. Schedule for tomorrow 9:00 AM

  Done! Post scheduled successfully.
  Post ID: abc-123
🧠

Routines

Recurring work on a schedule

Save the task as a routine. Your Bot runs it on a schedule from the cloud, checks for new content, and posts it to Facebook automatically — no manual trigger needed.

Also Works with Claude Code

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code. See the Claude Code guide for Facebook, the guide for any AI agent, or connect over the Postiz MCP server.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, 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: Done! Scheduled on Facebook for
  tomorrow at 9:00 AM.

Cross-post Facebook content to other platforms

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

Example

> Post "Excited to announce our new feature!" to
  Facebook and LinkedIn tomorrow at 9am, then schedule
  a daily tip on Facebook every weekday at 10am

Grok Bot: Done! Scheduled:
  - Facebook + LinkedIn: tomorrow 9:00 AM
  - Daily tips on Facebook: Mon-Fri 10:00 AM

Facebook rules Grok Bot follows

Grok Bot reads the Facebook rules from postiz integrations:settings before scheduling. These are the ones that most often change what gets published.

  • ✓Postiz posts to Facebook Pages you manage, not personal profiles. Connect the Page in Postiz before asking the Bot.
  • ✓Use the url field for rich link previews. If you paste a link in the text only, Facebook may not render the preview card.
  • ✓Images and video must be uploaded with postiz upload first; the Bot cannot attach a raw local path or external URL.
  • ✓Run postiz integrations:settings before scheduling. Postiz returns the current Facebook rules and Grok Bot honors them.

Grok Bot and Facebook: frequently asked questions

How do I post to Facebook from Grok Bot?

Add the Postiz plugin with /add-plugin postiz and store your POSTIZ_API_KEY as a Bot secret. Ask the Bot to post to your Facebook Page. It finds the Page in Postiz, writes the copy, attaches a link preview or media, and schedules it. You approve before it publishes.

Can Grok Bot post to a Facebook Page or only a profile?

Postiz connects Facebook Pages, so Grok Bot posts to Pages you manage. Connect each Page in Postiz and it shows up in integrations:list. If you run several Pages, name the one you mean and the Bot targets it, or post the same update to all of them.

Can Grok Bot add a link preview to Facebook posts?

Yes. Give the Bot a URL and it sets the url field so Facebook renders a rich link card with the page title and image. This is more reliable than pasting the link inside the text. You can still add your own intro copy above the preview.

Can Grok Bot attach photos or video to Facebook posts?

Yes. Point the Bot at a file on its cloud computer or in your workspace. It runs postiz upload first, then attaches the returned media to the post. Supported formats include PNG, JPG, MP4, and MOV. Raw paths and external URLs are not accepted by Postiz.

Can Grok Bot post to Facebook on a schedule while I am away?

Yes. Save the task as a routine and the Bot runs it from its own cloud computer, drafting the post, scheduling it through Postiz, and reporting back. It asks for approval before publishing, so a human stays in the loop even when the routine runs unattended.
