As the WordPress API matures, this is an important moment to take stock and consider the best use-cases. We’ll briefly take a bird-eye view of the API, before deep-diving into different ways the API has been deployed. We’ll see an examples of the API as an integration tool for running dual CMSs, as a public-facing queryable dataset, as a big data visualisation tool and as a way to share large sets of data. Along the way, I’ll share ways to make your API implementation more efficient – and share some of the pitfalls and mistakes we’ve made. We’ll take a look at decoupling both the frontend and backend of WordPress – and answer the obvious question – why continuing using WordPress?
