paypal php rest api. response codes? - php

Question

This whole paypal process has been one nightmare after the next. I've managed to complete the application all except for one small problem. the response object from paypal Payment::execute() has no documentation. My front end is client side, so i really have no way of knowing what this response array contains.
here's what i've got so far:
$paymentId = $this->ppconf; //stores paymentId
if(empty($paymentId)){Throw New \Exception('missing payment id'); }
$payment = Payment::get($paymentId, $apiContext);
$execution = new PaymentExecution();
$execution->setPayerId($z);
$response = $payment->execute($execution, $apiContext); // i need to know what this response array looks like and what the response codes are, so i can generate my $result array for my application.
$state = $response->getState();
$failures = ['failed','canceled','expired'];
if(in_array($state,$failures)){
$result = ['type'=>'error'];
}else{
$result = ['type'=>'success'];
$this->finished = true;
}
return $result;

Answer 1

As per the docs: https://developer.paypal.com/webapps/developer/docs/api/#execute-an-approved-paypal-payment
Returns a payment object for the completed PayPal payment.
So presumably an instance of an PayPal\Api\Payment Object.
You should be able to grab the state property of the payment using the following:
$response->getState();
Returning one of the following strings:
created, approved, failed, canceled, expired
