API (Application Programming Interface)

An Application Programming Interface (API) is a set of protocols and tools that allow different software applications to communicate. APIs enable developers to integrate third-party services, automate workflows, and extend software capabilities without reinventing the wheel. RESTful APIs, GraphQL, and WebSocket APIs are common types used across web and mobile applications.

Key Features:

• Standardized communication – Allows seamless integration between apps.

• Scalability – Supports multiple users and services.

• Security protocols – Uses authentication methods like OAuth and API keys.

• Flexibility – Works across different programming languages and platforms.

Best Use Cases:

• Third-party integrations (e.g., payment gateways, social logins).

• Cloud computing services.

• IoT applications.

• Automating business workflows.
