I am trying to use the paypal php sdk that I downloaded from github at this link: https://github.com/paypal/PayPal-PHP-SDK. I saved the project in the correct directory on my web server. What file do I need to include so that I can use the libraries? Composer is not installed on my hosting, so I would prefer to just include the library with the require statement. The API docs are located here: https://developer.paypal.com/docs/api/
Thanks in advance!
There would be no setup files required. All the libararies are included in your downloaded SDK.
Run the PayPal-PHP-SDK/paypal/rest-api-sdk-php/sample/index.php from your project root directory.
