The simplest way to add the plugin to your site is to use WordPress' *Add Plugin* screen to search the plugins in the WordPress.org repository. Once on the add *Add Plugin* page, search for **CallTracker** and click install. Alternatively, you can download the plugin from [here](https://wordpress.org/plugins/calltracker/).

Once you've added the plugin, **Activate** it so we can configure it in the next steps.

### Retrieve Your Call Tracker DNI API Key

You'll now need to get your **Dynamic Number Insertion API Key** from **Dynamic Number Insertion** settings. Go to your Call Tracker dashboard > Settings > Integrations > Dynamic Number Insertion, and you'll see your Company DNI API Key. Click **Copy** to add it to your clipboard.
