Hello,
I am using the code example from Square Connect API OAuth Ruby Example, but I am encountering an issue. The page returns a 400 Bad Request error, and the screen is empty
The URL I used is:
https://squareupsandbox.com/oauth2/authorize?client_id=sandbox-sq0idb-c4UHQJ4HVi2OnAyxKJMfzA
I’ve tried it in the past and it worked without any issue.
Could you please help me identify what I might be missing or misconfiguring?
Thank you.
