Install the Tracking Template just for one specific Google Ads Campaign (or override the main one)

If you need to apply ClickSambo tracking only to specific Google Ads campaigns, or if a particular campaign requires unique tracking parameters different from your account-wide settings, you should set the tracking template directly at the Campaign level. Doing this overrides any account-level template just for that campaign.

Steps: 
In Google Ads, go to your Campaigns list.
Select the campaign you want to configure by clicking its name.
Go to the Settings for that individual campaign.
Find the Campaign URL options (this might be under an Additional settings dropdown).
Paste your specific ClickSambo tracking parameters (obtained from your ClickSambo dashboard) into the Tracking template box you see there.
