APIs are the backbone of modern applications, but they are often overcomplicated. This simple visual breaks down the main API types: REST, SOAP, GraphQL, Internal APIs, and Partner APIs, with real-world use cases like login systems, payments, and live data. Whether you're a beginner or a seasoned developer, understanding these distinctions is essential.
- REST – The most common, used for web services and CRUD operations.
- SOAP – A protocol with strict standards, often used in enterprise environments.
- GraphQL – Allows clients to request exactly the data they need, reducing over-fetching.
- Internal APIs – Used within an organization to connect internal systems.
- Partner APIs – Exposed to specific business partners for integration.
