I downloaded the php sample code for Google Checkout, (from https://code.google.com/p/google-checkout-php-sample-code/downloads/list) and am attempting to get pollingdemo.php to work.
My issue is the following:
$merchant_id = "XXXXXXXX";
$merchant_key = "XXXXXXXXX";
$environment = "sandbox";
$certificate_path = "?????????"; // set your SSL CA cert path
I do not know what to enter for the certificate path. I do own an SSL certificate and it is enabled for my site. I called my hosting provider, and they did not know what I should enter there either.
Alternatively, I would like to implement Polling without an SSL, which should be possible according to this. However, I do not know how to do this with pollingdemo.php.
Thanks in advance
