private function auth()
    {
        $postvals = "grant_type=client_credentials";

    }

Ce que je veux

Obtenir le statut terminer sur paypal.

Ce que j'obtiens

J'obtien le statut Non récupéré.

Je ne vois quel étape il me reste a faire.
J'utilise les liens checkout V2.
Et j'ai tenté d'utilisé l'api fourni par paypal mais je me retrouve au même résultat.
Je suis obligé de confirmer le paiement manuellement sur l'interface paypal.
