I know you can't use PHP with wix code but if you place a php file in the backend can you access it from the HTML component?
I'm asking because I would like to use Square as my payment processor, but you cannot do this strickly with HTML. I realize Wix supports Square in conjunction with the Wix Store App, but I can't use the App for what I am doing. Subsequently, I can only use the Square Payment or Checkout API.
Any and all input would be greatly appreciated. Thanks!
