What is an API?
An API (Application Programming Interface) is a "bridge" for communication between different software, allowing programs to call functions or access data from other programs through predefined rules—without needing to understand underlying details.
Core Functions
- Function Reuse：Avoid redundant development.
- Data Sharing：Open partial functions to external users.
Common Types
- REST API：Based on HTTP, with a simple interface.
- SOAP API：Based on XML, with high security.
Workflow
- The client sends a request.
- The server processes and verifies permissions.
- Data is returned.
Key Elements
- API Key：Authenticates identity to prevent unauthorized calls.
- Request Methods：Such as GET (retrieve data) and POST (submit data).
- Data Formats：Commonly JSON/XML.
