    Is an API Always Necessary for Server-Client Communication?

    It is clear that a server and a client are programs communicative iwth each other using one or more protocols (HTTP, TCP, etc.) I conceptually understand what an API is: it is like an intermediary between two programs that makes integration easy. For example, we build app A and want to connect...
