Question

Hi I noticed that there are 3 example requests in examples.

authorize purchase capture

I keep getting Security Header invalid error messages so I tried to write my own code to test.

All I want to do is to set off a purchase via express checkout without sending credit card details.

My code thus far:

<?php


echo 'testing the omnipay';

require __DIR__.'/../Vendor/autoload.php';

use Omnipay\Common\GatewayFactory;

$gateway = GatewayFactory::create('PayPal_Express');
$gateway->setUsername('some_username');
$gateway->setPassword('some_password');
$gateway->setSignature('some_signature');
$gateway->setTestMode(true);

echo 'start';
$params = array(
    'amount' => '1.99',
    'currency' => 'SGD',
    'description' => 'test purchase',
    'transactionId' => '123',
    'transactionReference' => '123ref',
    'returnUrl' => 'http://localhost:8000/gateways/PayPal_Express/completeAuthorize',
    'cancelUrl' => 'http://localhost:8000/gateways/PayPal_Express/authorize',

 );


echo 'end';

$response = $gateway->capture($params);
echo 'after capture';
echo '<pre> ';
print_r ($response);
echo '</pre> ';

My output is:

Solution

I keep getting Security Header invalid error messages

Please double check your username, signature and password set to gateway.

You could find them on https://developer.paypal.com/ Applications -> Sandbox Accounts.

Choose one business account (if not exist you have to create it) and click "Profile". Then open tab "API credentials". That's it.

Note: That your code is not completed, it should contain check of response(redirect? success?) and a call of purchaseComplete method when you come back from paypal.
