Key Roles of APIs:
- Facilitate integration between platforms.
- Enable real-time data sharing.
- Support scalable and modular software development.
Types of APIs

|--------------------|-----------------------------------------------------------------------------|----------------------------|
| Web APIs | Accessed via HTTP/HTTPS; used for web-based services. | RESTful APIs, SOAP APIs |
| Open APIs | Publicly available with minimal restrictions. | Google Maps API, Twitter API |
| Internal APIs | Used within organizations to streamline systems. | Enterprise resource tools |
| Partner APIs | Shared selectively with business partners. | Vendor integrations |
| Composite APIs | Combine multiple APIs into a single call. | Microservices aggregation |
