API Protocols
API Protocols
1. REST (Representational State Transfer)
– An architectural style for designing networked applications.
– It emphasizes stateless communication, the use of standard HTTP methods (GET, POST, PUT, DELETE), and resources identified by URLs.
2. GraphQL
– A query language for APIs that allows clients to request exactly the data they need, nothing more and nothing less.
– This efficiency is a major advantage over REST, where endpoints often return fixed data structures.
3. SOAP (Simple Object Access Protocol)
– A protocol for exchanging structured information in the form of XML messages over a network.
4. gRPC (Google Remote Procedure Call)
– A high-performance, open-source framework for remote procedure calls (RPCs).
– It uses Protocol Buffers (a compact binary format) for data serialization.
5. Webhooks
– A mechanism for real-time communication between applications.
– A webhook is essentially an HTTP callback triggered by a specific event in one system, which sends a notification to another system.
6. WebSockets
– A protocol providing full-duplex communication channels over a single TCP connection.
– WebSockets enable real-time data exchange between a client and a server.
7. MQTT (Message Queuing Telemetry Transport)
– A lightweight publish-subscribe messaging protocol designed for low-bandwidth, high-latency, or unreliable networks.
– It is commonly used in IoT (Internet of Things) applications.
8. AMQP (Advanced Message Queuing Protocol)
– An open standard protocol for message-oriented middleware.
– AMQP provides features like reliable message delivery, routing, and queuing, making it suitable for enterprise integration scenarios.
9. EDA (Event-Driven Architecture)
– A software architecture pattern where applications react to events (e.g., user actions, sensor readings).
– EDA promotes loose coupling and scalability.
10. EDI (Electronic Data Interchange)
– A set of standards for exchanging business documents (e.g., purchase orders, invoices) electronically between organizations.
– EDI is widely used in supply chain management and logistics.
11. SSE (Server-Sent Events)
– A server-push technology that allows a server to send updates to a client over an HTTP connection in a unidirectional manner.
