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.
Important notes
Create new GTM Container for direct integration with iClosed as Google wont allow you to use the same container that you've connected your website with.
How to connect GTM with iClosed
Here's the step-by-step guide:
Go to your Google Tag Manager
create new Container for integration with iClosed
Copy Container ID
Navigate to
Integrations page → Google Tag ManagerClick the "Connect" button
Initiate integration by clicking on the "Connect Google Tag Manager" button and new window will appear from where you'll:
Name of your iClosed - GTM integration
Paste GTM container ID
Click on "Save Changes" button to finish integration
Startup subscription plan users will have the ability to add one Google Tag Manager ID, while Business and Enterprise will be able to add up to three Google Tag Manager ID's. (learn more about iClosed pricing and feature breakdown here).
GTM Container Configuration
Once you have connected your Google Tag Manager with iClosed, it's time to configure integration from Google's side. Follow the next steps:
Picking up iClosed Events
Navigate back to Google Tag Manager → click "Submit" to publish changes
Click Preview to troubleshoot
Tag assistant will open scheduler in different browser window
Run a test by filling out all information and booking a call so you can capture all events. Tag Assistant activates Google debug mode. This tool allows you to debug your website, including iFrame, within a single session, providing detailed diagnostics to help you validate, diagnose, and resolve your implementation ( learn more on how to troubleshoot it here).
Click Finish in Tag Assistant once you're done
Once you're back in Google Tag Manager, you'll see that
You will see that events are showing on the left
Page View - iclosed_view
Potential - iclosed_potential
Qualified - iclosed_qualified
Disqualified - iclosed_disqualified
Call booked - iclosed_call_scheduled
Pro tips
Kindly note that if you have both email and phone number included on your event form, GTM will trigger twice, once phone number and email are entered both.
That said, for every lead that books a call you will receive 2 x Potential, 1 x qualified and 1 x call booked (iclosed_call_scheduled).
Creating Tags
After you've finished testing, you should create tags for events you'd like to push further to tracking tools (e.g. GA4, Google Ads, etc...).
Select Workspace tab
Click on the Tags on the left → and then New button at the top right corner of the section
Choose tag type
Choose Tag type per your preference
Configure tag → the most important part is to tie event exactly as it's delivered in Tag Assistant (or copy from here):
Save, and hit Preview again to run another test and you'll see Tags included along with events.
Pro tips
When configuring the custom trigger for a tag, make sure to select "All custom events" as shown below.
When adding GA4 to your GTM, make sure to set the parameters below in the configurations
cookie_domain=auto
cookie_flags=SameSite=None;Secure
Editing and removing Google Tag Container ID
In case you need to edit your Google Tag Container ID, you can do it easily by clicking on the "Edit" button on the right side of the screen.
Additional options are to:
Deactivate integration on the toggle button
Remove GTM Container ID
Click on the three dots on the far right of the screen
Click on the "Remove GTM" button
As soon as you click on it, warning message will appear for you to confirm the removal.
Kindly note that deactivating connection will not allow you to add additional Google Tag Manager Container ID's than it's available according to your subscription plan.
