APIs are not always an "easy button" for headless commerce solutions, as they can be poorly designed and lead to increased complexity and frustration for developers. While many professional headless commerce platforms offer enhanced developer API options, not all APIs are the same, and some may require multiple calls just to fill a user's shopping cart. A well-designed headless commerce API delivers logical data for use in a single call, providing seamless integration of data and processes. In contrast, poorly designed APIs can hide important functions or limit developer access behind plugins and paywalls. It's essential to find an API that meets your business needs and not rely on generic assumptions about all headless commerce solutions being the same.
