I have my own domain and had been using this resource on Github as the foundation for years: https://github.com/spreadshirt/shoppartnerdemos/tree/master/basketcreation.
It allowed me to fetch product and article information to populate the pages of my website using simplexml. Now with the changes to the API requiring an API key for everything, my entire site is broken.
Every product page gives an 500 error because namespaces can’t work anymore with the api key rquirement.
I’m a self-taught PHP novice. I only knew as much as I needed to get my site working. I have no idea where to begin to fix this.
