Thank you for your code snippet Aaron, but I’d really like to try and get what I had working rather than starting over again. I figured maybe I just couldn’t execute the curl from an file that I’m requiring like that, so I took all three files I’m using for the PayPal processing and combined them into one. Then, I put it into a code snippet which I call from the site and I’m still hitting the ’OR die’ on the curl_exec you’ll see below. Here is my entire code snippet:
