Estou tentando vincular o Paypal Express Checkout em PHP no meu site, ele gera o link certinho e redireciona o usuário à tela de pagamento. Porém, quando clica em continuar para pagar, ele redireciona ao return_url do site e não faz a transação
public function checkout()
{
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'https://api-m.paypal.com/v2/checkout/orders');
curl_setopt($curl, CURLOPT_HTTPHEADER, [
'Content-Type: application/json',
'Authorization: ' . $this->getAccessToken(),
'Prefer: return=representation'
]);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode([
'brand_name' => 'yStore Plugins',
'intent' => 'CAPTURE',
'landing_page' => 'BILLING',
'user_action' => 'PAY_NOW',
'purchase_units' => $this->getItems(),
'application_context' => [
'notify_url' => $this->getNotificationURL(),
'cancel_url' => $this->getCancelURL(),
'return_url' => $this->getReturnURL()
]
]));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = json_decode(curl_exec($curl));
curl_close($curl);
return $response->links[1]->href;
}
private function getAccessToken()
{
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'https://api-m.paypal.com/v1/oauth2/token');
curl_setopt($curl, CURLOPT_HTTPHEADER, [
'Content-Type: application/x-www-form-urlencoded',
'Authorization: Basic ' . base64_encode($this->getClientId() . ':' . $this->getClientSecret())
]);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, 'grant_type=client_credentials');
$response = json_decode(curl_exec($curl));
curl_close($curl);
return $response->token_type . ' ' . $response->access_token;
}
