What types of APIs, besides REST, are you familiar with?

In addition to REST, I am familiar with several types of APIs:

• SOAP (Simple Object Access Protocol) — a message exchange protocol that uses XML. Often used in enterprise systems.
• GraphQL — a query language for APIs that allows clients to request exactly the data they need.
• gRPC — a high-performance remote procedure call framework that uses Protocol Buffers.
• WebSocket API — for bidirectional real-time communication.
• RPC (Remote Procedure Call) — a general approach to invoking functions on a remote server.

Each of them is suitable for different tasks and has its own features in implementation and testing.
