NOT_ENABLED_FOR_CARD_PROCESSING Paypal authorize order

$res = $client->sendAsync($request)->wait();
echo $res->getBody();

When I want to approve the payment, it gives me an error, so I don’t know what to do since the same example executed is the same as the api.

Answer

Receiving and transmitting card numbers through your own server poses a very high risk, has a high compliance burden, and it is very likely that you should not be attempting to do this.

Consider an integration that uses hosted card fields, such as Advanced Credit and Debit Cards. There are also gateways such as Braintree.

You must enable the account for processing before you can integrate them. See the documentation.
