- Before we take a closer look at calling APIs in Java, let's talk a bit about who the course is for and what you should know ahead of time. Senior Java developers are expected to provide advanced solutions that go beyond writing simple logic or working with objects. These solutions often require systems to exchange information, which is commonly done through an API these days. APIs are one of the best ways to pass data or share capabilities between systems so it's a skill that advanced Java developers must have. So if you're a beginning Java developer who knows the basics, this course will teach you how to call APIs which will prepare you for the integration problems that you're going to face as you advance in your career. Also, if you're just interested in what's possible with an API, this course can also benefit you. There are a couple technologies and concepts that kind of layer on top of each other throughout the course. I can unpack most of that information but you're going to get the most from this course if you have a little background in a couple of areas. The only things you must know to get through the course is how to work with an IDE and some basic Java. I'll be using Eclipse but you can use any IDE of your choice. If you've never worked with Java or you want to understand the basics, there's better courses in the LinkedIn learning platform for that. Go check those out, then come back and watch this course. There are some technologies in the background that will help us throughout the course. But you don't have to know those upfront. There are bits of Maven, Spring, Jackson and Project Reactor sprinkled throughout the course but nothing that you must know ahead of time. Also, if you know a little bit about HTTP it'll go a long way in this course. The course does require you to sign up for a few accounts, all of which are free or free with a trial. So you'll need to register for Azure, Twitter and a Twilio account. The Azure account will require a credit card but they're really good about not billing you past the trial. These accounts will come with some credentials. So it's important you store them securely. But for the demo purposes, I'm going to store them in an environment variable on my workstation. So make sure you know how to create that for your system and whatever operating system you're using. Throughout the course, we'll be using these credentials and other information that's associated with the account, so make sure that you use your information and not mine. So for example, we'll be making calls to Twilio and there's a phone number associated with the account. The examples will not work if you use my Twilio phone number. That's all there is to know. I can guide you through the rest of the materials from here. Let's go ahead and get started.
