Course details

APIs have become ubiquitous. It's not an exaggeration to say that the web runs on APIs. If you're looking to advance as a web designer or even just talk tech as a project manager, then it's imperative that you have a basic understanding of APIs. In this course filled with useful information and hands-on challenges, Andrew Probert offers you a gentle introduction to APIs that removes many of the barriers to getting started. Find out what an API is, what JSON is, and how you can use APIs and JSON to work with objects and parse data. Learn how to connect to an API, navigate API documentation, make a request, use parameters to filter the response, and more. Deep dive into working with the Giphy API, then go over how to handle errors and security. Plus, learn about the basics of GraphQL and how to query data from a GraphQL API.
