Google is actively rolling out non-numeric “custom” URLs for it’s users and pages.
yes, we’ve got one too: https://google.com/+Nextscripts
This +NextScripts is not our page ID and it cannot be used in our API.
Here is how to get the numeric page ID:
1. Login to your account, go to “pages” and select your page.
2. You will see the front of your page with the new URL. Click “Manage this page” button.
3. You will get to the dashboard and dashboard will show the numeric ID in the URL.
Alternately you can just click “Manage this page” right from the pages selection.
