Is this the path I enter into the registration? I keep getting 400 errors when I run my app
containing an http call and want to rule out the problem that I’ve not registered the app correctly.
The redirect URL is where the user gets sent after they authorize your application. The 400 is most likely due to not sending a Client-ID header or client_id query parameter containing the Client ID of the application you registered (it’s on the same page where you set the redirect URL).
