I tested recurring payments in sandbox. I created customer paypal account with zero ballance and without Bank accounts. When I made recurring payment from this account. I created profile with some initial payment (setup_fee). And set max_fail_attempts to 1. By default, PayPal does not activate the profile if the initial payment amount fails. But my profile successful activated and has status ACTIVE instead PENDING. And I received on WebHook PAYMENT.SALE.COMPLETED event type. I expected get some FAIL event type (PAYMENT.SALE.PENDING or PAYMENT.SALE.DENIED), because customer account have not enough money. Why it happened? I need to Cancel recurring payment profile if does not enough money in customer account.
