API (Application Programming Interface) is an interface that enables different software applications to communicate with each other. Through API integration, automatic data flow between your systems is ensured.

Types of APIs

• REST API: The most widely used web API standard
• SOAP API: Protocol preferred in enterprise systems
• GraphQL: Flexible data querying
• WebSocket: Real-time communication

API Security

For API security, mechanisms like OAuth 2.0, JWT tokens and rate limiting should be used.

Integration Process

For a successful API integration, documentation analysis, test environment setup and error management are critical steps.
