Designing Web APIs

Prerequisites:

• Familiarity with APIs
• Web programming experience (Javascript, ASP.NET, PHP, C#, etc.)

Audience

• Developers

Overview:

Web API is an application programming interface for connecting applications. It enables the exchange of information and interoperability between applications through the web.

This instructor-led, live training (online or onsite) is aimed at developers who wish to design, write, and build web APIs while taking advantage of existing technologies to develop high-value products.

By the end of this training, participants will be able to:

• Set up the necessary development environment to start developing web APIs.
• Understand the core concepts, architecture, and common uses of web APIs.
• Build a strategy on developing highly valuable web APIs.
• Learn how to define the web API architecture and specifications.
• Apply the best practices of API security, design, and scaling throughput.
• Learn how to build, test, debug, and publish web APIs.
