How to get a SharePoint Microsoft List ID (GUID) in the browser

Thanks to Salaudeen Rajack, who blogged various ways to get a SharePoint List ID, I found this the easiest one, so I am re-documenting it for myself. It simply involves crafting a URL to hit the rest API in the browser, no PowerShell or Graph Explorer needed.

Grab the URL of your list, e.g.

https://moderncomms987892.sharepoint.com/sites/M365ChangePilot/Lists/M365%20Roadmap/AllItems.aspx

We need to complete a URL in this format to get to the rest API:

https://Your-Domain/Your-Site/_api/web/lists/getByTitle(‘ListTitle’)/Id

In this case, Your-Domain/Your-Site/ is moderncomms987892.sharepoint.com/sites/M365ChangePilot/

And ListTitle is M365%20Roadmap

So the URL we need is: https://moderncomms987892.sharepoint.com/sites/M365ChangePilot/_api/web/lists/getByTitle(‘M365%20Roadmap’)/Id

Which will give us the result in the screenshot above. The ID is the Edm.Guid
