To retrieve your Site ID from SharePoint, visit your site, log in, and modify your URL to include your specific domain, site name, and subsite. For example, if your domain is “orecons,” your site name is “test,” and your subsite is “test_subsite,” the URL will look like this: `https://orecons.sharepoint.com/sites/test/test_subsite/_api/web`.

Scroll down to the content section and look for the element `` to find the Site ID, or, if you have admin rights, locate the Site ID in the SharePoint admin console by navigating to the list of all active sites and selecting the desired site.
