About this plugin
GMB Poster turns your WordPress posts into a steady stream of Google Business Profile (GBP) updates. New posts join a queue, the scheduler picks a slot from your cadence, and at slot time GMB Poster either:
- Auto-publishes the post directly to your GBP location via the official Google Business Profile API (v2.0+), or
- Prepares the caption, image and tracked link and hands it off to you for a one-click publish in the GBP web interface (the original semi-manual mode).
You pick the mode in Settings. You can switch any time.
Auto-publish (recommended, v2.0+)
- Create a free Google Cloud project, enable the My Business APIs, paste your OAuth Client ID + Secret into GMB Poster Settings. (Step-by-step guide is built into the setup wizard.)
- Click Connect Google account — Google’s consent screen opens, you pick the Google account that manages your GBP, click Allow.
- Pick your GBP location from the dropdown.
- Flip the Auto-publish toggle on.
From then on, every time a queued post hits its scheduled slot, GMB Poster posts it directly to your GBP location automatically. Posted items show a green “Posted” pill and the Google post ID. Failed items show a red “Failed” pill with the Google API error and a one-click Retry publish button.
Why “per-install” OAuth credentials? org and risk Google revoking it for everyone. Instead, each install uses its own free Google Cloud project; the OAuth Client Secret and the refresh token are stored encrypted-at-rest in your WordPress database using a key derived from your site’s AUTH_KEY constant.
Semi-manual mode (original)
If you don’t want to set up a Google Cloud project, the original semi-manual handoff still works:
- New WordPress posts are added to the GMB Poster queue automatically (configurable per post type and category).
- The scheduler picks a posting slot using either time-of-day slots or a cooldown window.
- When a slot is due, the next item appears in your Dashboard widget and on the GMB Poster Queue screen.
- Click Prepare & open GBP. GMB Poster:
- copies the formatted caption to your clipboard,
- downloads the featured image to your computer,
- opens your GBP composer in a new browser tab.
- In GBP: paste the caption, drop in the image, set the call-to-action, click Publish.
- Click Mark posted back in WordPress.

External services
GMB Poster communicates with the official Google Business Profile API when (and only when) you’ve connected a Google account and turned on Auto-publish:
- Google OAuth 2.0 ( https://accounts.google.com/o/oauth2/v2/auth, https://oauth2.googleapis.com/token, https://oauth2.googleapis.com/revoke ) — used to obtain, refresh and revoke the access token GMB Poster uses on your behalf.
- My Business Account Management API ( https://mybusinessaccountmanagement.googleapis.com/ ) — to list the GBP accounts your Google login can manage.
- My Business Business Information API ( https://mybusinessbusinessinformation.googleapis.com/ ) — to list the locations under each account so you can pick one.
- Google My Business API v4 ( https://mybusiness.googleapis.com/ ) — to create local posts on the location you selected. This is the actual “publish” call.
When and what is sent:
* The OAuth handshake sends nothing about your WordPress posts — only your chosen Google account’s permission to act on its behalf.
* For each post we publish on your behalf, we send the caption text, the URL of your featured image, the call-to-action button text + URL, and the post’s language code. We do not send any visitor data, analytics, or anything else.
If you do not connect a Google account, GMB Poster never contacts Google. The semi-manual mode opens GBP in your browser as a normal page navigation (your browser, your session — exactly as if you had clicked a regular link).
