Welcome to the API introduction tutorial! APIs (Application Programming Interfaces) are essential for building modern web applications and enabling communication between different systems. Let's explore the basics together.
What is an API?
An API is a set of rules and protocols that allows applications to interact with each other. It acts as a bridge, enabling data exchange and functionality sharing without requiring developers to understand the underlying implementation.
- Key Characteristics:
- Standardized 🔄
- Modular 📦
- Scalable 📈
Why Use APIs?
- Integration 🌐: Connect services like weather services, payment gateways, or social media platforms.
- Reusability 🔄: Share components across projects.
- Security 🔒: Abstract sensitive logic from direct exposure.
Example Use Cases
- Fetching data from a database 🗄️
- Authenticating users 🔐
