This document discusses APIs and how they can be used to integrate different applications together. It defines what an API is and how APIs allow programs to interact with and extract data from other applications. It then outlines several common approaches for integrating systems together, including using direct API calls from one system to another, developing custom middleware that processes requests and responses between systems, or building logic into one of the integrated applications. The document emphasizes that APIs enable easy and cheap integration of data from various sources to create new applications and solutions without needing developers.

▪ Technical Details around APIs – How do APIs
work?
▪ Orchestrating APIs together – who’s in charge?
▪ Open APIs – Open Data
▪ Demos!

System
• Baked into one of the solutions.
• Uses direct API calls.
• Constrained by the features of the
vendor who implements it.
• Typically the easiest to deploy – if it
exists!
• Business logic belongs to the
integrator – not the system being
integrated with.
Logic

21. • Baked into one of the solutions.
• Uses direct API calls.
• Similar to an integration.
• Customizable, event-driven.

31. ▪ APIs let you write or COMPOSE together
applications that use other applications.
▪ Data is EVERYWHERE, ready to be used by your
systems.
▪ Public APIs make integration EASY and CHEAP.

32. ▪ NO DEVELOPERS NEEDED – with a little bit of
training you can do this yourself!
▪ The power to create is in YOUR hands.
▪ NO MORE WAITING for releases – if you need it,
DO IT.
