Connectivity and APIs

Introduction

• Instant connectivity connects the world at our fingertips.
• Enables purchasing, posting, and interaction across devices and applications.

What is an API?

• Definition: An Application Programming Interface (API) is a set of routines and protocols in computer programming.
• Function: Acts as a messenger, taking requests and telling a system what to do, then returning responses.

API Analogy

• Restaurant Example:
  • Menu = Choices available to order from.
  • Kitchen = System that prepares the order.
  • Waiter (API) = Communicates your order to the kitchen and delivers the food back to your table.

Real-World API Example: Airline Flights

• Process:
  • Searching for flights is like ordering from a menu.
  • You input variables (departure city, date, return city, etc.) on the airline's website.
  • The airline's API allows online travel services to access the airline's database.
• Online Travel Services:
  • Aggregate information from multiple airlines using APIs.
  • Interact with airline systems to book seats and preferences.

Importance of APIs

• APIs facilitate interactions between applications, databases, and devices.
• They create the connectivity that enhances our digital experiences.

Conclusion

• Think of APIs as waiters delivering data between applications.
• For creating APIs, consider MuleSoft as a solution.
