Post to Google My Business from Codex

Codex can post to your Google Business Profile (Google My Business) through Postiz. Install the Postiz skill or add the Postiz MCP server to Codex, connect the profile in Postiz, then describe the update. Codex picks standard, event, or offer, fills dates, coupon codes, and call-to-action buttons, and schedules the post.

What is Codex?

Codex is OpenAI's coding agent. It runs as the Codex CLI in your terminal (npm install -g @openai/codex), as an IDE extension, and in the cloud, and it can run shell commands and call MCP servers, which is how it drives Postiz. Codex is not ChatGPT: ChatGPT is the chat assistant on chatgpt.com and connects to Postiz differently (see the ChatGPT guide). For the full setup, start at the Codex + Postiz hub.

💻

Terminal & IDE Native

Codex runs in your terminal or IDE. You type what you want in plain English and it handles Postiz for you — no extra configuration needed.

🔧

Autonomous Execution

Codex runs commands inside a sandbox with approval rules you control, and works through multi-step tasks like discovering channels, uploading media, and scheduling Google My Business posts.

⚡

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 two ways: the postiz skill, which it loads from .agents/skills or ~/.agents/skills and which you can invoke with $postiz, or the Postiz MCP server added with codex mcp add. Either way it learns the available tools and chains them for Google My Business workflows.

✓Install the Postiz skill with npx skills add, or add the Postiz MCP server with codex mcp add
✓Codex loads skills from .agents/skills and reads SKILL.md to learn the Postiz CLI
✓Authenticate with POSTIZ_API_KEY or postiz auth:login; the MCP route uses OAuth instead
✓Codex runs commands in its sandbox and asks for approval based on your permission settings
✓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

# Or add the Postiz MCP server instead (OAuth, no API key)
codex mcp add postiz --url https://mcp.postiz.com/mcp-oauth-dynamic
codex mcp login postiz

# Then ask, interactively or headless
codex "list my social media integrations"
codex exec "post today's changelog to Google My Business"

GMB 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.

Just Ask Codex

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

Codex: I'll handle that.
  Found your GMB integration.
  Composing and scheduling the post.

  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 Google My Business

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 GMB workflows.

✓Runs in your terminal or IDE — just type what you want
✓Autonomous execution in sandboxed environments
✓Parallel task support — post while coding
✓Automatically select STANDARD, EVENT, or OFFER based on your message
✓Cross-post to GMB + other platforms in a single session
✓Powered by OpenAI's most capable models

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 Google My Business guide, or the Postiz Agent page for any other agent.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your GMB integration, determines the right post type and CTA settings, and publishes the update.

Claude Code

> Create a Google My Business event post
  for our grand opening on March 15th
  from 10am to 6pm, with a Book CTA

Claude: Done! Scheduled on Google My Business for
  tomorrow at 9:00 AM.

Can Codex post to Google My Business and other platforms at once?

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

Example

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

Codex: Done! Scheduled:
  - Google My Business + LinkedIn: tomorrow 9:00 AM
  - Daily tips on Google My Business: Mon-Fri 10:00 AM

What can I ask Codex to post on Google My Business?

Codex takes plain-English prompts in an interactive session, as a one-off codex exec command, or through the $postiz skill. These are the kinds of prompts people type for Google My Business.

Prompts for Google My Business

> Post a 20% off offer to our Google Business Profile with coupon SEPT20,
  valid through Sunday, CTA "Get offer" linking to our pricing page

$ codex exec "Create an EVENT post on Google My Business for the workshop
  on 2026-10-03 from 18:00 to 20:00 with a Book CTA"

> $postiz Post a standard update about our new opening hours
  with the storefront photo

What Google My Business rules should Codex follow?

These are the Google My Business limits and required settings Postiz enforces. Codex reads them from postiz integrations:settings, and you can mention any of them in your prompt.

✓topicType is STANDARD, EVENT, or OFFER.
✓EVENT posts need eventTitle plus eventStartDate and eventEndDate (YYYY-MM-DD) and eventStartTime and eventEndTime (HH:MM).
✓OFFER posts can carry offerCouponCode, offerRedeemUrl, and offerTerms.
✓callToActionType is one of NONE, BOOK, ORDER, SHOP, LEARN_MORE, SIGN_UP, GET_OFFER, or CALL, with callToActionUrl for the link.
✓Photos go through postiz upload before they are attached.

Codex and Google My Business FAQ

How do I post to Google My Business from Codex?

Install the Postiz skill with npx skills add gitroomhq/postiz-agent, or add the Postiz MCP server with codex mcp add postiz --url https://mcp.postiz.com/mcp-oauth-dynamic. Connect Google My Business in Postiz once, then ask Codex in plain English what to post and when. Codex resolves the Google My Business settings, uploads any media, and schedules the post.

Can Codex create Google Business Profile event and offer posts?

Yes. Codex sets topicType to EVENT or OFFER based on your prompt. Events need eventTitle plus start and end dates in YYYY-MM-DD and times in HH:MM, which Codex formats for you. Offers can carry offerCouponCode, offerRedeemUrl, and offerTerms. Plain updates use STANDARD and need none of these.

Which call-to-action buttons can Codex add?

Google supports BOOK, ORDER, SHOP, LEARN_MORE, SIGN_UP, GET_OFFER, and CALL, or NONE for no button. Say "add a Learn more button linking to our pricing page" and Codex sets callToActionType and callToActionUrl accordingly. CALL uses the phone number on your profile, so it needs no URL.

Can Codex post to Google My Business on a schedule without me watching?

Yes. Postiz stores scheduled Google My Business posts and publishes them at the chosen time, so Codex does not need to stay open. For unattended runs, call codex exec with your prompt from a script or cron job. Keep a human reviewing the output, since Codex will publish exactly what it is told to publish.

Do I need a Postiz API key to post to Google My Business from Codex?

Not with the MCP route. Run codex mcp login postiz and Codex signs in to your Postiz account over OAuth, so it only reaches channels you already connected, including Google My Business. The CLI skill route needs either postiz auth:login or a POSTIZ_API_KEY environment variable. Your Google My Business login itself never leaves Postiz.

Is posting to Google My Business from Codex the same as posting from ChatGPT?

No. Codex is OpenAI's coding agent for your terminal and IDE, and it reaches Postiz through the Postiz skill or MCP server. ChatGPT is the chat assistant on chatgpt.com, which connects to Postiz as an app or custom MCP connector. Both can publish to Google My Business; see the ChatGPT guide for that setup.
