How to do OAUTH CLIENTS works

I´m trying to connect Bitrix24 with Sugar via API available in Bitrix, but seems there no Sugar response.
I made OAUTH CLIENTS but it´s not working. I can´t get an active token and this error massages.
Notice: Undefined index: name in C:\xampp\htdocs\suite\include\SearchForm\SearchForm2.php on line 624

Could someone help me with this issue?

XAMPP doesn’t really work well with SuiteCRM until you turn off display_errors in php.ini and restart web server.

I don’t know if that will solve this particular issue, though, it might only clean the errors from the screen…
