Other methods of data transfer — REST API, gRPC, SSE, Webhooks, etc.?

There are several popular methods for data transfer between systems:

• REST API — an architectural style that uses HTTP requests (GET, POST, PUT, DELETE) for interaction. Simple, widely used, well-suited for CRUD operations.

• gRPC — a modern high-performance remote procedure call protocol that uses HTTP/2 and Protocol Buffers for serialization. Suitable for microservices and high-load systems.

• SSE (Server-Sent Events) — a technology for one-way data transfer from server to client in real-time via HTTP. Used for data updates without constant requests.

• Webhooks — a callback mechanism where one system notifies another about an event via HTTP request. Allows for asynchronous integration.

Each method has its advantages and use cases; the choice depends on performance, reliability, and system architecture requirements.
