Orchestration is everywhere. Any application that uses more than 1 service does some kind of API orchestration – and how many experiences only use 2? On average, most apps use somewhere between 26 and 50 APIs, according to Postman in 2024.
Getting data from all of these APIs into the right shape for our users is complex. We need to consider error handling, retries, parallelization, caching, and so many more functional and non-functional requirements. We’ve historically handled this orchestration logic in a bunch of different ways – and they’re all costly. Costly to those of us writing the apps, and even our users. But what would happen if we could reduce the cost of API orchestration to basically $0?

In this talk, we’ll explore different approaches to API orchestration from the client to the server, imperative to declarative, and see what happens when the time it takes to integrate an API goes from months to days.
