How to link your Google Tag Manager account to your Website
VIA allows you to link a Google Tag Manager (GTM) account to your website.
You can then use your GTM account to install third party applications to your website such as website chatbots, Facebook pixels, or review widgets, and specify what website pages they appear on.
Linking your GTM account to your website using VIA
Create a new GTM account at http://tagmanager.google.com , or use an existing account that you’ve already setup for your business
Login to your GTM account and copy your Google Tag Manager Container ID
Login to VIA
In the left hand menu, go to Settings > Configuration
Go to Third Party > Google > Tag Manager
Paste your Google Tag Manager Container ID into the Code field
You have now added linked your GTM account to your website. The information will automatically be saved once it has been entered so you can close this tab
Your VIA software/website will now be fully synced with your Google Tag Manager account. You can now login into your GTM account to add third party code snippets and triggers, then test them before putting them live on your site.
Your third party should be able to help you with their setting up their application using GTM
