Developers use application programming interfaces to hide complexity, organize code, design reusable components, and connect different systems, applications, or services.

ESRI will offer a complimentary Web seminar this month on how to use the new ArcGIS JavaScript APIs to build high-performance, easy-to-use online mapping applications.

Microsoft is opening up Excel to developers with a new JavaScript API. It will let developers use custom data types like images, cards, and arrays.

Microservices also make it easy to expose services to external users using APIs, perhaps relying on rich JavaScript clients to generate web pages and views on the client device.

APIs can eliminate the need to collect, validate, and organize content and data. Applications can be developed much faster and at a lower cost using CareerOneStop’s standardized, tested datasets.

Take advantage of API key authentication to control the access of applications and services to your Web APIs in ASP.NET Core.
