What is an API?

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines how software components should interact, making it easier to integrate services and share data.

  • Key Features:
    • Enables seamless integration between systems
    • Supports multiple data formats (JSON, XML, etc.)
    • Provides standardized methods for requests and responses
    • Allows for secure communication through authentication mechanisms

Common API Types

  1. REST API 📡

    • Uses HTTP methods (GET, POST, PUT, DELETE)
    • Stateless and client-server architecture
    • Example: REST API in Action

  2. GraphQL API 📊

    • Allows clients to request exact data needs
    • Reduces over-fetching and under-fetching issues
    • Example: GraphQL API Guide

  3. SOAP API 🧾

    • Uses XML for messaging
    • Emphasizes strict standards and security
    • Example: SOAP API Overview

Best Practices for Using APIs

  • Always check the rate limits and authentication requirements
  • Use versioning to manage API changes
  • Implement error handling for robustness
  • Refer to the API Development Standards for guidelines
