Questions about .pem certificate file

[dmikester1]

I created a .pem certificate in my sandbox account. Now where do I put that on my server? Anywhere I want? Then do I just change this line to point to it? curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/cert/cacert.pem"); I can get the example_usage.php working using the cacert.pem file. But how do I get it working with my own file? Or can I just use the cacert.pem in production? I wish there was a bit more documentation about all this.
