API design and integration involve creating and integrating APIs that enable communication between different software components. It ensures that the system is modular and interoperable.

• Process:
  • API Design: Designers define the API’s endpoints, methods, and data formats.
  • Implementation: Developers implement the API and ensure it meets performance and security requirements.
  • Integration: Developers integrate the API with other system components and third-party services.
• Purpose:
  The goal of API design and integration is to create a modular and interoperable system that supports seamless communication between components.
• Outcome:
  A well-designed and integrated API that enhances system functionality and interoperability.
• Challenges:
  Ensuring API security and performance can be challenging. Additionally, managing versioning and backward compatibility requires careful planning.
• Best Practices:
  • Use RESTful principles to design APIs that are easy to use and maintain.
  • Implement robust security measures, such as authentication and rate limiting.
  • Regularly test and monitor API performance.
