Integrations
Third-party keys and services Kalium connects to, starting with Google Maps.
Appearance -> Customize -> General -> Integrations is where Kalium stores keys for outside services.

Google Maps API Key
Google requires every website that displays a Google Map to have its own API key. Without one, a map shows as a gray box with a warning across it rather than your location.
Paste your key here and every map on your site uses it, the Map element in WPBakery, and anything else that draws a Google map.
Getting a key
Go to the Google Maps Platform
Create a project and enable the Maps JavaScript API
Create an API key and copy it
Paste it into this field and publish
Restrict your key to your own domain in the Google Cloud console. An unrestricted key can be used by anyone who views your page source, and Google bills the key's owner.
Google also requires billing details on the account, though normal traffic for a small site typically falls within their free monthly allowance.
If your map shows a gray box
Work down this list:
Is a key entered here? This is the usual answer.
Is the Maps JavaScript API enabled for that key's project? A key with the wrong API enabled fails the same way.
Are the key's domain restrictions right? A key restricted to
example.comwon't work onstaging.example.com.Is billing set up on the Google Cloud account? Google disables keys without it.
The exact reason is usually printed on the gray box itself, or in your browser's developer console.
WPBakeryOther integrations
Not everything Kalium works with lives on this screen, most integrations need no key at all and simply activate when their plugin does:
WooCommerce
The entire shop option group, header cart elements, product cards
WPML
The Language Switcher element, and translation of builder content
Breadcrumb NavXT
Breadcrumbs, with Kalium's styling
Elementor and WPBakery
Kalium's own widgets and elements
ACF Pro
The Parameters and Options panel
If a setting looks like it's doing nothing, an inactive plugin is a common cause. Some settings stay visible regardless, the Breadcrumb screen among them, and builder elements stay in the list grayed out. The whole WooCommerce option group is the exception: without the plugin it does not appear at all.
