Slim and Stripe namespaces

Is the following call possible in slim with stripe ?
I seem to be boinking on anything to do with stripe Namespaces?
This would be a super shame, Stripe is becoming the giant in on line payments very rapidly…

 case 'checkout': 
                    \Stripe\Stripe::setApiKey('sk_test_7PlIUekk4t8rngfmXhiWnnza');
                    $session = \Stripe\Checkout\Session::create([
                        'payment_method_types' => ['card'],
                        'line_items' => [[
                        'name' => $run->DriveFromName,
                        'amount' => $run->Charge * 100,
                        'currency' => 'usd',
                        'quantity' => 1,
                        ]],
                        'payment_intent_data' => [
                        'application_fee_amount' => $run->Charge * 3.9,
                        ],
                        'success_url' => "https://easymoneycheaprides.com/?session_id={$session->Id}",
                        'cancel_url' => "https://easymoneycheaprides.com/?session_id=failure",
                    ], [
                        'stripe_account' => $run->DriveAcct,
                    ]);
                    break;
