This version only uses the basic API scope that all eBay applications have access to.
Array ( [clientId] => Leebarth-listings-PRD-a07736cc6-8e372b00 [clientSecret] => PRD-07736cc658c5-270d-4268-b6f3-3389 [ruName] => Lee_bartholomew-Leebarth-listin-lbnljg [redirectUri] => https://ebaylister.ddns.net/ebay/auth.php [scope] => Array ( [0] => https://api.ebay.com/oauth/api_scope ) [sandbox] => [authHost] => https://auth.ebay.com )
This will attempt to get an application token directly from eBay using your client credentials.
Try the OAuth flow with only the basic scope:
1. If this basic scope works, you'll need to request additional scopes in your eBay Developer account.
2. Log in to your eBay Developer account and check which scopes are assigned to your application.
3. Modify your application code to only use the scopes that your application has been granted.
