The API Apps support within Azure App Service provides additional support that enables you to easily create, consume and call APIs - both APIs you create (using a framework like ASP.NET Web API or the equivalent in other languages) as well as APIs from other SaaS and cloud providers. During the presentation we will explore the fundamentals of creating, calling & consuming REST APIs using ASP.NET Web API on Azure. We will also examine a test case of using an API from a third-party cloud provider within Azure.
