Integrating with a single API can be tough, let alone multiple APIs. I see integration being about on-boarding, exploration, education, authenitcation, code samples, testing and sandboxing. This API Integration project involves everything between discovery of APIs and going into production.
The goals is to find building blocks, tools, services and other knowledge that will help developers integrate APIs into their web, mobile and internet of things applications. This area of API evangelist is brand new and will be evolving as I continue my research.
If you have tools or approaches to development of apps using APIs, please let me know. I'd love to hear more about how you approach integration.
