6 Essential API Styles to Stay Ahead of the Curve

An API style acts as a covert handshake between two computers, allowing them to communicate and interpret one another’s messages. Each type of handshake has a unique method for exchanging and receiving information! ๐ŸŒŸ๐Ÿ—ฃ๏ธ

Are you feeling lost when it comes to API styles? Don’t worry, you’re not alone! ๐ŸŒ๐Ÿค” I’ve got your back!

I’ve simplified and decrypted the mysteries of the six most crucial API styles for you so you can focus on what really matters and save time!

1. ๐—ฆ๐—ข๐—”๐—ฃ

  • Protocol using XML-based messages for communication
  • Requires strict adherence to predefined contracts
  • Operates primarily over HTTP or HTTPS
  • Commonly used in enterprise environments


  • REST API is an architectural style that emphasizes resources and statelessness.
  • It uses standard HTTP methods such as GET, POST, PUT, and DELETE.
  • REST API is simpler to implement and understand compared to SOAP.
  • It can work with different data formats, but JSON is the most commonly used.

3. GRPะก

  • GRPะก focuses on remote procedure calls (RPCs) between services.
  • It uses HTTP/2 for transport and Protocol Buffers for serialization.
  • It is ideal for microservices, where low latency and high efficiency are essential.
  • GRPะก automatically generates client and server code for multiple languages.


  • GraphQL is a query language and runtime for APIs.
  • It allows clients to request specific data, reducing over-fetching.
  • GraphQL can combine multiple data sources in a single request.
  • It was developed and open-sourced by Facebook.


  • WebSocket is a bidirectional, real-time communication protocol.
  • It maintains a single, long-lived connection over TCP.
  • WebSocket is suitable for web applications requiring live updates.
  • It is not tied to any specific serialization format.


  • Webhook is a server-side, event-driven mechanism.
  • It sends HTTP callbacks (usually POST requests) to specified URLs.
  • Webhook is triggered by specific events or actions within an application.
  • It is useful for integrating third-party services or updating data in real-time.
