What is install path for plugin?

I start using piwik for my e-commerce store tracking, the store is on magento. I want to track e-commerce, for that i download plugin.
There are input fields required for that. Currently i am using piwik cloud…
I know the site_id and auth_token but what is install_path for the plugin

Meant is the path to your Matomo installation, so if you use the cloud: https://thesubdomainyouchoose.matomo.cloud

Thanks for your support, yes i use that same as you mention for my cloud:
But my sales are not shown in e-commerce…
