Google Tag Manager is a tag management system that allows you to set up and manage tags on your site without changing your website's code.
It acts as a centralized "media connector" for managing and deploying tracking tags across multiple platforms from a single interface, and as such it will be a bridge between your 
iClosed scheduler and multiple platforms and services (e.g. Google Analytics and Ads, Meta Pixel, LinkedIn insight tag, etc...), providing you valuable and precise engagement and conversion insights.

Integrations page and click the "Connect" button to start.

You can test the flow by using using Google Tag Assistant Chrome Extension.
Tag Assistant helps you install and troubleshoot your Google tags, including Google Analytics, Google Ads and Tag Manager on your webpage.
