I am trying to use the Square SDK with a WordPress website. I installed Composer and the Square SDK. I created a WP_Rest_API, but when trying to use the Square classes inside of the .php file, I get an error.
- I created a new plugin in my wordpress plugins folder.
- In the .php file inside my plugin, I require the "autoload.php" file of Composer from my root directory.
- When trying to use the classes from the Square SDK I get an error.
