Menu
I'm trying to integrate the PayPal SDK into my site but have run into a problem which I cannot find a solution for in the documentation or via Stackoverflow.
I use a standard set-up:
start.php:
<?php
//require 'vendor/autoload.php';
require __DIR__ . '/../vendor/autoload.php';
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;
define('BASE_URL', 'http://localhost:80/paypaltut/');
if(!defined("PP_CONFIG_PATH")){
define('PP_CONFIG_PATH', '../vendor/paypal/rest-api-sdk-php/tests/');
}
$clientid = 'ARe54bHOzRcn13nRglDpIst46bWOp6pyBRYlP4nulwwTL2ivIuKlIJrUp5LdgZfuC0qPbqIuGdVFsmeK';
$clientsecret = 'EJarieZ8B_6WEZ__gZl0uS-Dmc-ypa1RH1joF1u4_XlJje2IINBRCsARhNyZk-dJG7kBJS8ceQF5GNVr';
$apiContext = new ApiContext(new OAuthTokenCredential($clientid, $clientsecret));

When I attempt to process the payment using the paypal sandbox version of my app, I get the error:

I have gone through the process of creating the app through the paypal developer's dashboard, I've tried adding a new ApiContext to teh pay (return url ) file and still get the same error. anybody know how to fix this one?
oh an I'm using the v1.5.0 sdk and php 5.6.1

Found the root cause.
You forgot to pass $apiContext object to execute call in your pay.php code.
try {
$result = $payment->execute($execute);
}
catch(Exception $e) {
die($e);
}
Change it to this, and it should work:
try {
$result = $payment->execute($execute, $apiContext);
}
catch(Exception $e){
die($e);
}
