PHP Fatal error

When I try to connect to quickbook using php server to make my accounting app using the accounting api I get :

fatal error: uncaught quickbooksonline\api\exception\sdkexception: [0]: the code is not set. can't exchange for oauth 2 access token. thrown in /applications/xampp/xamppfiles/htdocs/helloworld-php/vendor/quickbooks/v3-php-sdk/src/core/oauth/oauth2/oauth2loginhelper.php on line 218.

I entered my keys correctly and didn't touch anything else, I also installed the v3-php-sdk

Do you see error=invalid_scope in the callback URL?

Edit config.php and remove com.intuit.quickbooks.payment from the scope. Save your changes (this removes the Payments API from the scope).

Refresh the page before clicking "Connect to QuickBooks" again.

Are you using a Production company and you require Payments API?

Make sure that Payments is turned on and properly configured for your company.
