The debate between RPC and REST APIs is a longstanding one among software developers, with each style having its own advantages and use cases. RPC, or remote procedure call, is a straightforward approach that involves executing a function on a server, while REST, or representational state transfer, is a more semantic-oriented style that presents resources to the outside world through standard conventions. RPC is well-suited for high-performance APIs, synchronous service-to-service communication, and real-time data processing, whereas REST is ideal for building easily navigable APIs, decoupling consumers from underlying systems, and supporting multiple consumers with differing needs. Ultimately, the choice between RPC and REST depends on the specific requirements of the API, and some organizations may even employ both styles to achieve their goals.
