Yes. Once the API token is created you can reuse it on any site. What’s important here is parameter Unique URLs and Sessions. The total amount of reports can’t exceed limits defined for Unique URLs and Sessions. A session is a single report sent from the client. However, the reports are sent only when there are changes on the page. If the page doesn’t change then the report is not being sent. The sessions counter is connected to the Workspace so you can have any amount of sites, but total sessions are limited by your subscription plan.
