Press the “Generate Key” button and copy the API key to the clipboard by pressing the “Copy To Clipboard” button.

Go to your site, unroll the Crocoblock > JetPlugins settings, and select the plugin to which you need to add the API key.

Once added, the API key is available for other plugins. For example, when added to the JetElements’ settings, the API key is also accessible for the JetPopup plugin, and vice versa. Unroll the appropriate tab (the Integration tab of the JetElements or the JetPopup settings) and paste the copied API key into the “MailChimp” field.
