What the author says it does

Many themes and plugins load Google Maps without an API key, or without a setting to enter one. Google requires an API key for every Maps JavaScript API request, so these maps fail with “This page can’t load Google Maps correctly” or show a “For development purposes only” watermark.

API KEY for Google Maps fixes this without touching theme or plugin code. Enter your key once and the plugin adds it to every Google Maps JavaScript API script enqueued on the site.

Features

Adds your API key to Google Maps JavaScript API scripts enqueued by any theme or plugin.
Replaces an outdated or different key already present in the script URL with your own.
Adds the callback parameter Google has required since January 2023, fixing the JavaScript error Loading the Google Maps JavaScript API without a callback is not supported.
Works on the front end of your site and in the WordPress admin.
One-click Generate API Key button that opens the Google Cloud Console with the Maps APIs selected.
Quick link to a free tool that checks your site for Google Maps API key errors.
Lightweight: a single settings field and a tiny inline script. The saved key is removed when you delete the plugin.

How to use

Activate the plugin and go to Settings > Google API KEY.
Click Generate API Key (you must be signed in to your Google account), or paste a key you already have.

The opening of the plugin's own description. The full text, installation notes and changelog are on its WordPress.org page.

Read from the WordPress.org plugin API on October 31, 2026, when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin. The author takes donations at their donate page.
